How to install GeoIP and mod_geoip2 on centos for apache

1) yum install GeoIP GeoIP-devel GeoIP-data zlib-devel

2) mkdir /usr/local/share/GeoIP

3) Download the latest Country and City database files from maxmind

cd /usr/local/share/GeoIP
wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCountry/GeoIP.dat.gz
wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz
gunzip GeoIP.dat.gz
gunzip GeoLiteCity.dat.gz

4) yum install httpd-devel apr-devel

5) wget http://geolite.maxmind.com/download/geoip/api/mod_geoip2/mod_geoip2_1.2.5.tar.gz

6) tar xvzf mod_geoip2_1.2.5.tar.gz && cd mod_geoip2_1.2.5

7) apxs -i -a -L/usr/lib64 -I/usr/include -lGeoIP -c mod_geoip.c

8) Enabling mod-geoip
Nothing’s going to work unless mod-geoip is enabled in your apache configuration. You’ll need the following lines in your httpd.conf file (located on CentOS systems at /etc/httpd/conf/httpd.conf)

<IfModule mod_geoip.c>
GeoIPEnable On
GeoIPDBFile /usr/local/share/GeoIP/GeoIP.dat Standard
GeoIPDBFile /usr/local/share/GeoIP/GeoLiteCity.dat Standard
</IfModule>

9) Restart Apache so your changes will take effect by entering the following command.

#/etc/init.d/httpd restart

10) /usr/local/bin/geoipupdate

How to configure multi master MySQL replication

How to configure multi master MySQL replication

By | | Comments 2 comments

Introduction ~

I was planning to write article on Multi Master MySQL replication since long time; Finally started now!. Please refer the the article on “How to configure MySQL replication with one Master” URL ~ http://www.indiangnu.org/2007/mysql-replication-one-master-multiple-slave/

* Let me inform you all that Multi Master replication in MySQL is purely based on following two variables. It has nothing to do with replication technology used in MySQL replication….

mysql> show variables  like  ‘%increment_%’;

+—————————————+——-+
| Variable_name                                   | Value |
+—————————————+——-+
| auto_increment_increment    |  1    |
| auto_increment_offset               |  1    |
+—————————————+—–+
2 rows in set (0.00 sec)

mysql>

** Requirements ~

a) Master Hosts (2 master in my case) ~

master-1 => 10.66.66.194
master-2 => 10.66.90.135
b) Replication Slave (1 slave) ~
slave => 10.66.75.137

c) MySQL server (with replication support)

** Let us understand how it works ?

* Master-1 Server =>

Set following variables…

mysql> set auto_increment_increment=5;
mysql> set auto_increment_offset=1;

mysql> show variables like ‘%increment_%’;
+————————–+——-+
| Variable_name            | Value |
+————————–+——-+
| auto_increment_increment | 2     |
| auto_increment_offset    | 1     |
+————————–+——-+
2 rows in set (0.00 sec)

mysql>

** Create Table ~

mysql> create table class ( rollno INT(5) NOT NULL PRIMARY KEY AUTO_INCREMENT , name VARCHAR(30) );

** Add Record now ~

mysql> INSERT INTO class VALUES (”,’Arun Bagul’);
mysql> INSERT INTO class VALUES (”,’Ravi Bhure’);
mysql> INSERT INTO class VALUES (”,’Karthik Appigita’);
mysql> INSERT INTO class VALUES (”,’Ameya Pandit’);

mysql> SELECT * FROM class;
+——–+——————+
| rollno | name             |
+——–+——————+
|      1 | Arun Bagul       |
|      3 | Ravi Bhure       |
|      5 | Karthik Appigita |
|      7 | Ameya Pandit     |
+——–+——————+
4 rows in set (0.00 sec)

mysql>

* Master-2 Server =>

Set following variables…

mysql> set auto_increment_increment=2;
mysql> set auto_increment_offset=2;

mysql> show variables like ‘%increment_%’;
+————————–+——-+
| Variable_name            | Value |
+————————–+——-+
| auto_increment_increment | 2     |
| auto_increment_offset    | 2     |
+————————–+——-+
2 rows in set (0.00 sec)

mysql>

** Create Table ~

mysql> create table class ( rollno INT(5) NOT NULL PRIMARY KEY AUTO_INCREMENT , name VARCHAR(30) );

** Add Record now ~

mysql> INSERT INTO class VALUES (”,’Nilkanth Parab’);
mysql> INSERT INTO class VALUES (”,’Nishit Shah’);
mysql> INSERT INTO class VALUES (”,’Ram Krishna’);
mysql> INSERT INTO class VALUES (”,’Suhail Thakur’);

mysql> SELECT * FROM class;
+——–+——————+
| rollno | name             |
+——–+——————+
|      2 | Nilkanth Parab   |
|      4 | Nishit Shah      |
|      6 | Ram Krishna      |
|      8 | Suhail Thakur    |
+——–+——————+
4 rows in set (0.00 sec)

mysql>

** What is the importance of “auto_increment_increment” and “auto_increment_offset” ~

mysql> desc class;
+——–+————-+——+—–+———+—————-+
| Field  | Type        | Null | Key | Default | Extra          |
+——–+————-+——+—–+———+—————-+
| rollno | int(5)      | NO   | PRI | NULL    | auto_increment |
| name   | varchar(30) | YES  |     | NULL    |                |
+——–+————-+——+—–+———+—————-+

auto_increment_offset => This is BASE value for column with “auto_increment” attribute (please refer the above example)
auto_increment_increment => This is the increment value for column with “auto_increment” attribute

** If you combine the both tables (master-1 and master-2) the final table will look like this ~

mysql> SELECT * FROM class;
+——–+——————+
| rollno | name             |
+——–+——————+
|      1 | Arun Bagul       |
|      2 | Nilkanth Parab   |
|      3 | Ravi Bhure       |
|      4 | Nishit Shah      |
|      5 | Karthik Appigita |
|      6 | Ram Krishna      |
|      7 | Ameya Pandit     |
|      8 | Suhail Thakur    |
+——–+——————+
8 rows in set (0.00 sec)

mysql>

** This is how Multi master replication works….

auto_increment_offset=Nth master server
auto_increment_increment=M

Where –
N => nth number of master server (on master-1 keep it 1 and on master-2 keep it 2 and so on..)
M => Total number of Master Server (2 in our case but better to keep this value high so that we can add new master server easily)

log-slave-updates => Slave server does not log to its own binary log any updates that are received from a Master server. This option tells the slave to log the updates performed by its SQL thread to its own binary log.

** Make sure that MySQL is running and up on all master servers and slave server-

How to setup Multi Master MySQL replication ? –

Step 1] Create Database/Tables on  Master  & Slave Servers –

You can create DB on all master & slave server or  create on one server and export that DB on  rest of all servers…

Master-1 => Create DB and Table

mysql> create database student;

mysql> use student;

mysql> create table class ( rollno INT(5) NOT NULL PRIMARY KEY AUTO_INCREMENT , name VARCHAR(30) );

mysql> show tables;
+——————-+
| Tables_in_student |
+——————-+
| class             |
+——————-+
1 row in set (0.00 sec)

mysql> desc class;
+——–+————-+——+—–+———+—————-+
| Field  | Type        | Null | Key | Default         |      Extra          |
+——–+————-+——+—–+———+—————-+
| rollno | int(5)      | NO   | PRI | NULL    | auto_increment |
| name   | varchar(30) | YES  |     | NULL    |                |
+——–+————-+——+—–+———+—————-+
2 rows in set (0.00 sec)

mysql> SELECT * FROM class;
Empty set (0.00 sec)
mysql>

* Now take dump of “student” DB and export it on all master and Slave server…

[root@master-1~]# mysqldump -u root -p  -d student > /home/arunsb/student.sql

* SCP the dump file on master-2 and slave server ~
[root@master-1~]# scp /home/arunsb/student.sql arunsb@10.66.90.135:/tmp/student.sql
[root@master-1~]# scp /home/arunsb/student.sql arunsb@10.66.75.137:/tmp/student.sql

Login on master-2 and slave ~

mysql> create database student;

[root@master-2~]# mysql -u root -p student < /tmp/student.sql
Enter password:
[root@master-2~]#

[root@master-2~]# mysql -u root -p
Enter password:

mysql> use student

mysql> SELECT * FROM class;
Empty set (0.00 sec)
mysql>

** Please repeat the same steps on Slave server as well…

Step 2] Update “my.cnf” config file on master-1,master-2 and slave server –

[root@master-1~]# cat /etc/my.cnf

###########################
##MySQL replication setting

#Master setting(1)
server-id = 1
log-bin = /var/log/mysql/binary/mysql-bin.log
binlog-do-db = student
binlog-ignore-db = mysql
log = /var/log/mysql/mysql.log
auto_increment_offset=1
auto_increment_increment=5
log-slave-updates

##slave setting
master-port=3306
master-host=10.66.90.135
master-user=replication
master-password=mypwd
master-connect-retry=60
replicate-do-db=student
###########################

[root@master-1~]#

[root@master-2~]# cat /etc/mysql/my.cnf

###########################
##MySQL replication setting

#Master setting(2)
server-id = 2
log-bin = /var/log/mysql/binary/mysql-bin.log
binlog-do-db=student
binlog-ignore-db = mysql
log = /var/log/mysql/mysql.log
auto_increment_offset=2
auto_increment_increment=5
log-slave-updates

##slave setting
master-port=3306
master-host=10.66.66.194
master-user=replication
master-password=mypwd
master-connect-retry=60
replicate-do-db=student
###########################

[root@master-2~]#

* please create directory for binary log and set permission…

[root@master-1~]# mkdir -p /var/log/mysql/binary/
[root@master-1~]# chown mysql:adm  /var/log/mysql/ /var/log/mysql/binary/

[root@master-2~]# mkdir -p /var/log/mysql/binary/
[root@master-2~]# chown mysql:adm  /var/log/mysql/ /var/log/mysql/binary/

** MySQL Replication Slave ~

[root@slave~]# cat  /etc/my.cnf

[mysqld]

########################################
##slave setting
server-id=4
master-port=3306
master-host=10.66.90.135
master-user=replication
master-password=mypwd
master-connect-retry=60
replicate-do-db=student
########################################

[root@slave~]#


Step 3] Give Replication permission on both masters ~

** Master (1 & 2) ~

mysql> GRANT REPLICATION SLAVE ON *.* TO ‘replication’@’10.66.%.%’ IDENTIFIED BY ‘mypwd’;
Query OK, 0 rows affected (0.00 sec)

mysql>

Step 4] Restart MySQL on both master as well as replication slave server ~

** Please verify setting on master-1 and master-2 server…

* Master-1

mysql> show variables like ‘%increment_%’;
+————————–+——-+
| Variable_name            | Value |
+————————–+——-+
| auto_increment_increment | 5     |
| auto_increment_offset    | 1     |
+————————–+——-+
2 rows in set (0.00 sec)

* Master-2

mysql> show variables like ‘%increment_%’;
+————————–+——-+
| Variable_name            | Value |
+————————–+——-+
| auto_increment_increment | 5     |
| auto_increment_offset    | 2     |
+————————–+——-+
2 rows in set (0.00 sec)

** Please verify ‘master’ & ‘slave’ status on both masters(1 & 2) and slave –

mysql> show master status;
mysql> show slave status;

** Multi Master replication is started…

Step 5] Add few records on Master-1 & Master-2 server at same time ~

Add records on both master server at same time and check master and replication slave status as shown above….

** Add following on master-1

mysql> INSERT INTO class VALUES (”,’Arun Bagul’);
mysql> INSERT INTO class VALUES (”,’Ravi Bhure’);
mysql> INSERT INTO class VALUES (”,’Karthik Appigita’);
mysql> INSERT INTO class VALUES (”,’Ameya Pandit’);

** Add following on master-2

mysql> INSERT INTO class VALUES (”,’Nilkanth Parab’);
mysql> INSERT INTO class VALUES (”,’Nishit Shah’);
mysql> INSERT INTO class VALUES (”,’Ram Krishna’);
mysql> INSERT INTO class VALUES (”,’Suhail Thakur’);

** Please verify the numbers of records on both masters and slave….

mysql> SELECT * FROM class;
+——–+——————+
| rollno | name             |
+——–+——————+
|      1 | Arun Bagul       |
|      2 | Nilkanth Parab   |
|      6 | Ravi Bhure       |
|     11 | Karthik Appigita |
|     16 | Ameya Pandit     |
|     17 | Nishit Shah      |
|     22 | Ram Krishna      |
|     27 | Suhail Thakur    |
+——–+——————+
8 rows in set (0.00 sec)

mysql>

* So we all learned to configure multi-master MySQL replication. Enjoy!!

How to create or build RPM Package

How to create or build RPM Package

By | | Comments 17 comments

Introduction –

* “rpmbuild” tool is used to build both…

1) Binary Package ~ used to install the software and supporting scripts. It contains the files that comprise the application, along with any additional information needed to install and erase it.
2) Source Package ~ contains the original compressed tar file of source code, patches and Specification File.

* What is RPM & RPM package Manager?

The RPM Package Manager (RPM) is a powerful command line package management system capable of installing, uninstalling, verifying, querying, and updating software packages.

RPM package consists of an archive of files and meta-data used to install and erase the archive files. The meta-data includes helper scripts, file attributes, and descriptive information about the package.

* To build RPM package you need to specify three things ~

1) Source of application – In any case, you should not modify the sources used in the package building process.

2) Patches – RPM gives you the ability to automatically apply patches to them. The patch addresses an issue specific to the target system. This could include changing makefiles to install the application into the appropriate directories, or resolving cross-platform conflicts. Patches create the environment required for proper compilation.

3) Specification File – The specification file is at the heart of RPM package building process. It contains information required by RPM to build the package, as well as instructions telling RPM how to build it. The specification file also dictates exactly what files are a part of the package, and where they should be installed.

** Specification File ~ is divided in to 8 sections as shown below

a) Preamble ~ contains information that will be displayed when users request information about the package. This would include a description of the package’s function, the version number of the software etc.

b) Preparation ~ where the actual work of building a package starts. As the name implies, this section is where the necessary preparations are made prior to the actual building of the software. In general, if anything needs to be done to the sources prior to building the software, it needs to happen in the preparation section. The contents of this section are an ordinary shell script. However, RPM does provide two macros to make life easier. One macro can unpack a compressed tar file and cd into the source directory. The other macro easily applies patches to the unpacked sources.

c) Build ~ This section consists of a shell script. It is used to perform whatever commands are required to actually compile the sources like single make  command, or be more complex if the build process requires it. There are no macros available in this section.

d) Install ~ This section also containing a shell script, the install section is used to perform the commands required to actually install the software.

e) Install and Uninstall Scripts ~ It consists of scripts that will be run, on the user’s system, when the package is actually installed or removed. RPM can execute a script pre/post installation/removal of package.

f) Verify Script ~ script that is executed on the user’s system. It is executed when RPM verifies the package’s proper installation.

g) Clean Section ~ script that can clean things up after the build. This script is rarely used, since RPM normally does a good job of clean-up in most build environments.

h) File List ~ consists of a list of files that will comprise the package. Additionally, a number of macros can be used to control file attributes when installed, as well as to denote which files are documentation, and which contain configuration information. The file list is very important.

*** RPM’s requirement for build environment ~

A] RPM requires a set of directories to perform the build. While the directories’ locations and names can be changed. Default layout is shown below –

root@arunsb:~# ls -l /usr/src/redhat/

drwxr-xr-x 2 root root 4096 Aug 25  2007 SOURCES => Contains the original sources, patches, and icon files
drwxr-xr-x 2 root root 4096 Aug 25  2007 SPECS => Contains the specification files
drwxr-xr-x 2 root root 4096 Aug 25  2007 BUILD => Directory in which the sources are unpacked, & software is built
drwxr-xr-x 8 root root 4096 May 28  2008 RPMS => Contains the binary package files created by the build process
drwxr-xr-x 2 root root 4096 Aug 25  2007 SRPMS => Contains the source package files created by the build process

root@arunsb:~#

B] Need to export few global variables used by RPM –

root@arunsb:~# export  RPM_BUILD_DIR=/usr/src/redhat/BUILD/
root@arunsb:~# export  RPM_SOURCE_DIR=/usr/src/redhat/SOURCES/

Step 1] Create Specification (spec) File ~

root@arunsb:~# head -n 50  /usr/src/redhat/SPECS/openlsm.spec
# Authority: Arun Bagul

#RPM_BUILD_DIR    /usr/src/redhat/BUILD/
#RPM_SOURCE_DIR    /usr/src/redhat/SOURCES/

* “rpmbuild” tool is used to build both…

1) Binary Package ~ used to install the software and supporting scripts. It contains the files that comprise the application, along with any additional information needed to install and erase it.
2) Source Package ~ contains the original compressed tar file of source code, patches and Specification File.

* What is RPM & RPM package Manager?

The RPM Package Manager (RPM) is a powerful command line package management system capable of installing, uninstalling, verifying, querying, and updating software packages.

RPM package consists of an archive of files and meta-data used to install and erase the archive files. The meta-data includes helper scripts, file
attributes, and descriptive information about the package.

* To build RPM package you need to specify three things ~

1) Source of application – In any case, you should not modify the sources used in the package building process.

2) Patches – RPM gives you the ability to automatically apply patches to them. The patch addresses an issue specific to the target system. This could include changing makefiles to install the application into the appropriate directories, or resolving cross-platform conflicts. Patches create the environment required for proper compilation.

3) Specification File – The specification file is at the heart of RPM package building process. It contains information required by RPM to build the package, as well as instructions telling RPM how to build it. The specification file also dictates exactly what files are a part of the package, and where they should be installed.

** Specification File ~ is divided in to 8 sections as shown below

a) Preamble ~ contains information that will be displayed when users request information about the package. This would include a description of the package’s function, the version number of the software etc.

b) Preparation ~ where the actual work of building a package starts. As the name implies, this section is where the necessary preparations are made prior to the actual building of the software. In general, if anything needs to be done to the sources prior to building the software, it needs to happen in the preparation section. The contents of this section are an ordinary shell script. However, RPM does provide two macros to make life easier. One macro can unpack a compressed tar file and cd into the source directory. The other macro easily applies patches to the unpacked sources.

c) Build ~ This section consists of a shell script. It is used to perform whatever commands are required to actually compile the sources like single make  command, or be more complex if the build process requires it. There are no macros available in this section.

d) Install ~ This section also containing a shell script, the install section is used to perform the commands required to actually install the software.

e) Install and Uninstall Scripts ~ It consists of scripts that will be run, on the user’s system, when the package is actually installed or removed. RPM can execute a script pre/post installation/removal of package.

f) Verify Script ~ script that is executed on the user’s system. It is executed when RPM verifies the package’s proper installation.

g) Clean Section ~ script that can clean things up after the build. This script is rarely used, since RPM normally does a good job of clean-up in most build environments.

h) File List ~ consists of a list of files that will comprise the package. Additionally, a number of macros can be used to control file attributes when installed, as well as to denote which files are documentation, and which contain configuration information. The file list is very important.

*** RPM’s requirement for build environment ~

A] RPM requires a set of directories to perform the build. While the directories’ locations and names can be changed. Default layout is shown below –

root@arunsb:~# ls -l /usr/src/redhat/

drwxr-xr-x 2 root root 4096 Aug 25  2007 SOURCES        => Contains the original sources, patches, and icon files
drwxr-xr-x 2 root root 4096 Aug 25  2007 SPECS            => Contains the specification files
drwxr-xr-x 2 root root 4096 Aug 25  2007 BUILD            => Directory in which the sources are unpacked, and the software is built
drwxr-xr-x 8 root root 4096 May 28  2008 RPMS            => Contains the binary package files created by the build process
drwxr-xr-x 2 root root 4096 Aug 25  2007 SRPMS            => Contains the source package files created by the build process

root@arunsb:~#

B] Need to export few global variables used by RPM –

root@arunsb:~# export RPM_BUILD_DIR=/usr/src/redhat/BUILD/
root@arunsb:~# export RPM_SOURCE_DIR=/usr/src/redhat/SOURCES/

Step 1] Create Specification (spec) File ~

root@arunsb:~# head -n 50  /usr/src/redhat/SPECS/openlsm.spec
# Authority: Arun Bagul

#RPM_BUILD_DIR    /usr/src/redhat/BUILD/
#RPM_SOURCE_DIR    /usr/src/redhat/SOURCES/

%define MY_PREFIX    /usr/local/openlsm/

## Preamble Section-

tar xvfz ${RPM_SOURCE_DIR}/openlsm-0.99-r45.tar.gz -C ${RPM_BUILD_DIR}

## Build Section-
%build

cd ./openlsm-0.99-r45/
./configure –prefix=/usr/local/openlsm –with-mysql=/usr/bin/mysql_config –enable-internal-pcre –with-geoip=/usr –with-ldap=/usr –enable-trace

….. list of files installed by pkg
root@arunsb:~#

* How do you create the File List?

Creating the file list is manual process. What I did is I took the file list from my manual installed prefix directory with find command as shown below…

root@arunsb:~# find /usr/local/openlsm/ -type f -or  -type d

Step 2] Starting the Build ~

root@arunsb:~# cd /usr/src/redhat/SPECS
root@arunsb:/usr/src/redhat/SPECS# ls -l  openlsm.spec
-rw-r–r– 1 root root 12938 Dec  2 17:21 openlsm.spec

How to configure Jabber (jabberd2) with MySQL,PAM as auth database

How to configure Jabber (jabberd2) with MySQL,PAM as auth database

By | | Comments 20 comments

Introduction –

Jabberd2 is XMPP protocol based Instants Messaging (IM) server. Jabberd2 is highly scalable,high performance jabber server. The beauty of the Jabberd2 architecture lies in the fact that its component architecture distributes services across six components, each of which communicates over TCP/IP.

1) Router – is the backbone of Jabber server. It accepts connections from Jabberd components and passes XML packets between components
2) Server to Server (S2S) – component handles communications with external servers. S2S passes packets between other components and external servers, and it performs dial-back to authenticate remote Jabber servers.

3) Resolver  – acts in support of the S2S component. It resolves hostnames for S2S as part of dialback authentication.
4) Session Manager (SM)  – component implements instant messaging features like message passing,presence,roster and subscription etc. + DB connection
5) Client to Server (C2S) – component handles communication with Jabber clients like connection,passing packets to SM, authenticate and register users.
6) Jabber core  – logging and third party plugin communication.

** To compile/install Jabberd-2.2.9 we need following packages on Debian/Ubuntu (similar on Redhat/Fedora or other OS)

– libpam0g  libpam0g-dev (PAM support)
– openssl libssl-dev (TLS/SSL support)
– libudns0 libudns-dev (DNS Resolver Library)
– libidn11  libidn11-dev libnet-libidn-perl (libidn provides necessary string manipulation functionality for Jabberd2)
– mysql-common libdbd-mysql-perl  mysql-server-5.1  mysql-client-5.1 libmysqlclient16-dev (MySQL DB authentication)

**  Jabberd2 supports five authentication (user) mechanism –

* PAM
* MySQL Database
* Berkeley DB
* PostgreSQL Database
* SQLite DB
* OpenLDAP

** Following ports are used by jabberd2 –
* port 5222 – non-SSL client connection
* port 5223 – SSL client connection
* port 5269 – server to server connection
* port 5347 – jabberd2 router

Step 1] Create system User and Group for Jabberd 2  Server (http://codex.xiaoka.com/wiki/jabberd2:start) –

root@laptop:~# addgroup  –system  jabber
Adding group `jabber’ (GID 61) …
Done.
root@laptop:~#

root@laptop:~# adduser  –system  –home /usr/local/jabberd-2.2.9/ –shell /bin/false  –gid 61 jabber

* Verify system User and Group…  (steps for Ubuntu)

root@laptop:~# id jabber
uid=125(jabber) gid=61(jabber) groups=61(jabber)
root@laptop:~#

Step 2] Download the latest version of  Jabberd2 –

* Extract the source then compile/install it as shown below with PAM/MYSQL DB for authentication with SSL

root@laptop:/var/src/# wget -c http://codex.xiaoka.com/pub/jabberd2/releases/jabberd-2.2.9.tar.bz2

root@laptop:/var/src# tar xvfj  jabberd-2.2.9.tar.bz2

root@laptop:/var/src# cd jabberd-2.2.9

root@laptop:/var/src/jabberd-2.2.9# ./configure –prefix=/usr/local/jabberd-2.2.9/ –enable-debug  –enable-mysql  –enable-ssl –enable-pam  –enable-ssl
…
…..
checking for Libidn version >= 0.3.0… yes
checking for dns_init in -ludns… yes
checking gsasl.h usability… yes

checking for GnuSASL version >= 0.2.27… no
configure: error: no SASL backend available out of: gsasl
root@laptop:/var/src/jabberd-2.2.9#

Step 3] Facing problem  like “configure: error: no SASL backend available out of: gsasl” ~

Don’t worry download latest version of gsasl library from URL ~ http://alpha.gnu.org/gnu/gsasl/

* Download latest version of GNU SASL (gsasl) …

root@laptop:/var/src/# wget -c  http://alpha.gnu.org/gnu/gsasl/gsasl-0.2.29.tar.gz

* Extract the source then compile/install it …

root@laptop:/var/src# tar xvfz  gsasl-0.2.29.tar.gz
root@laptop:/var/src# cd gsasl-0.2.29/
root@laptop:/var/src/gsasl-0.2.29# ./configure –prefix=/usr/local/gsasl/
root@laptop:/var/src/gsasl-0.2.29# make
root@laptop:/var/src/gsasl-0.2.29# make  install
root@laptop:/var/src/gsasl-0.2.29#

* Verify the “gsasl” version

root@laptop:/var/src/gsasl-0.2.29# /usr/local/gsasl/bin/gsasl –version
gsasl (GNU SASL) 0.2.29

Step 4]  Go back to Jabberd2  source and start compiling/installing as shown in below –

root@laptop:/var/src/jabberd-2.2.9# ./configure –prefix=/usr/local/jabberd-2.2.9/  –enable-debug  –enable-mysql  –enable-ssl –enable-pam  –enable-ssl  –with-extra-include-path=/usr/local/gsasl/include/ –with-extra-library-path=/usr/local/gsasl/lib/
root@laptop:/var/src/jabberd-2.2.9# make
root@laptop:/var/src/jabberd-2.2.9# make install

**  Create log and runtime directories ~

root@laptop:/usr/local/jabberd-2.2.9# mkdir /usr/local/jabberd-2.2.9/var
root@laptop:/usr/local/jabberd-2.2.9# mkdir /usr/local/jabberd-2.2.9/var/run

root@laptop:/usr/local/jabberd-2.2.9#

Step 5] Configure jabberd-2.2.9 ~

* Setup (jabberid@laptop.ubuntu.me) Domain Name (hostname of server),IP address,port and log setting in client (c2s.xml) & server (sm.xml) configuration file –

NOTE ~ Domain Name not necessary to be hostname of server. But it should be resolvable (DNS) to one of the IP of server.

root@laptop:/usr/local/jabberd-2.2.9# hostname
laptop.ubuntu.me
root@laptop:/usr/local/jabberd-2.2.9#

root@laptop:/usr/local/jabberd-2.2.9# vi /usr/local/jabberd-2.2.9/etc/sm.xml

root@laptop:/usr/local/jabberd-2.2.9# vi /usr/local/jabberd-2.2.9/etc/s2s.xml

<pidfile>/usr/local/jabberd-2.2.9/var/run/s2s.pid</pidfile>
<log type=’file’>
<file>/usr/local/jabberd-2.2.9/var/log/s2s.log</file>

Step 6 ] Configure Jabberd-2.2.9 for Storage and Authentication 9using MySQL DB) –

* Make sure that database “Jabberd2” doesn’t exist (if exist either drop db or change DB name in db-setup.mysql file). If not export MySQL DB dump from Jabberd2 source…..

root@laptop:/usr/local/jabberd-2.2.9# mysql -u root -p  <  /var/src/jabberd-2.2.9/tools/db-setup.mysql
Enter password:
root@laptop:/usr/local/jabberd-2.2.9# mysql -u root -p
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 176
Server version: 5.1.31-1ubuntu2 (Ubuntu)

Type ‘help;’ or ‘\h’ for help. Type ‘\c’ to clear the buffer.

mysql> show databases;

+——————–+
15 rows in set (0.00 sec)

mysql>

*  Creating mysql user for jabberd2 ie ‘jabberd2’ with access to DB “jabberd2” –

mysql> GRANT select,insert,delete,update ON jabberd2.* to ‘jabber’@’localhost’ IDENTIFIED by ‘mypassword’;
Query OK, 0 rows affected (0.00 sec)

mysql>quit
Bye
root@laptop:/usr/local/jabberd-2.2.9#

* Now verify access to DB ~

root@laptop:/usr/local/jabberd-2.2.9# mysql -u jabberd2 -p
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 178
Server version: 5.1.31-1ubuntu2 (Ubuntu)

Type ‘help;’ or ‘\h’ for help. Type ‘\c’ to clear the buffer.

mysql> show databases;
+——————–+
| Database           |
+——————–+
| information_schema |
| jabberd2           |
+——————–+
2 rows in set (0.00 sec)

mysql> quit
Bye
root@laptop:/usr/local/jabberd-2.2.9#

Step 7] Change c2s.xml and sm.xml config file for MySQL DB support –

root@laptop:/usr/local/jabberd-2.2.9# vi /usr/local/jabberd-2.2.9/etc/c2s.xml

<!– Authentication/registration database configuration –>
<authreg>

<!– Backend module to use –>
<module>mysql</module>

<!– MySQL module configuration –>
<mysql>
<!– Database server host and port –>
<host>localhost</host>
<port>3306</port>

<!– Database name –>
<dbname>jabberd2</dbname>
<!– Database username and password –>
<user>jabberd2</user>
<pass>mypassword</pass>

root@laptop:/usr/local/jabberd-2.2.9# vi /usr/local/jabberd-2.2.9/etc/sm.xml

<!– Storage database configuration –>
<storage>
<!– Dynamic storage modules path –>
<path>/usr/local/jabberd-2.2.9/lib/jabberd</path>

<!– By default, we use the SQLite driver for all storage –>
<driver>mysql</driver>

<!– MySQL driver configuration –>
<mysql>
<!– Database server host and port –>
<host>localhost</host>
<port>3306</port>

<!– Database name –>
<dbname>jabberd2</dbname>
<!– Database username and password –>
<user>jabberd2</user>
<pass>mypassword</pass>

** To auto enable registration (in sm.xml file)

<auto-create/>

———————————-

NOTE ~ It is not enough to add users to the ‘authreg’ table because this only introduces users to the c2s component, but not to the sm component. Correct entries are required in the ‘active’ table as well. It is best to use a Jabber client to register users.

Step 8] Let’s start Jabberd-2 server (Test configuration) –

root@laptop:~# su -l jabber -s /bin/bash -c “/usr/local/jabberd-2.2.9/bin/jabberd -b”
root@laptop:~#

* check whether ports are open or not

root@laptop:~# netstat -nlp

Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
tcp        0      0 0.0.0.0:5347            0.0.0.0:*               LISTEN      31662/router

…
…..

root@laptop:~#

** Now Register the user “jabberd@laptop.ubuntu.me” and password “secret” using Jabber IM client

root@laptop:/usr/local/jabberd-2.2.9# tail -f var/log/c2s.log
…
Mon Oct 12 00:43:15 2009 [notice] [8] registration succeeded, requesting user creation: jid=jabberd@laptop.ubuntu.me

Mon Oct 12 00:44:20 2009 [notice] [9] [192.168.0.1, port=48307] connect

* Checking DB entry –

mysql> SELECT * FROM  active;
+————————–+—————–+————+

+———-+——————+———-+
| jabberd  | laptop.ubuntu.me | secret   |
+———-+——————+———-+
1 row in set (0.00 sec)

mysql>

=> Testing completed successfully….

Step 9] Configuring Jabberd2 for SSL/TLS Connections –

Let’s configure jabberd2 for SSL/TLS connection. Jabberd2 is designed to provide for SSL/TLS connections not only between Jabber clients and the server, but also between the Jabberd server components (sm, s2s and c2s) and the Jabberd router. A single SSL certificate may be used for these two functions (Jabber client to Jabberd and Jabberd component to router), or two separate keys may be used.

* Generate Self signed SSL Certificate…

root@laptop:/usr/local/jabberd-2.2.9# openssl req -new -x509 -newkey rsa:1024 -days 365 -keyout privkey.pem -out server.pem
Generating a 1024 bit RSA private key
.++++++
…..++++++
writing new private key to ‘privkey.pem’
Enter PEM pass phrase:
….
Common Name (eg, YOUR name) []:laptop.ubuntu.me
root@laptop:/usr/local/jabberd-2.2.9#

* Remove Passphrase from private key

root@laptop:/usr/local/jabberd-2.2.9# openssl rsa -in privkey.pem -out privkey.pem

** Combine the Private and Public Key and delete private key

root@laptop:/usr/local/jabberd-2.2.9# cat privkey.pem >> server.pem

root@laptop:/usr/local/jabberd-2.2.9# rm privkey.pem

* Change permission…

root@laptop:/usr/local/jabberd-2.2.9# chown jabber:jabber /usr/local/jabberd-2.2.9/server.pem
root@laptop:/usr/local/jabberd-2.2.9# ls  -l   /usr/local/jabberd-2.2.9
total 24
drwxr-xr-x 2 jabber jabber 4096 2009-10-11 22:17 bin
drwxr-xr-x 3 jabber jabber 4096 2009-10-12 01:03 etc
drwxr-xr-x 3 jabber jabber 4096 2009-10-11 20:16 lib
-rw-r–r– 1 jabber jabber 2217 2009-10-12 01:17 server.pem
drwxr-xr-x 3 jabber jabber 4096 2009-10-11 20:16 share
drwxr-xr-x 4 jabber jabber 4096 2009-10-12 00:20 var
root@laptop:/usr/local/jabberd-2.2.9#

root@laptop:/usr/local/jabberd-2.2.9# vi /usr/local/jabberd-2.2.9/etc/c2s.xml
<ssl-port>5223</ssl-port>
<pemfile>/usr/local/jabberd-2.2.9/server.pem</pemfile>

root@laptop:/usr/local/jabberd-2.2.9# vi /usr/local/jabberd-2.2.9/etc/s2s.xml

<pemfile>/usr/local/jabberd-2.2.9/server.pem</pemfile>

root@laptop:/usr/local/jabberd-2.2.9# vi /usr/local/jabberd-2.2.9/etc/sm.xml

<pemfile>/usr/local/jabberd-2.2.9/server.pem</pemfile>

<pemfile>/usr/local/jabberd-2.2.9/server.pem</pemfile>

** Now restart the server and check log …

root@laptop:/usr/local/jabberd-2.2.9# tail -f var/log/c2s.log

Mon Oct 12 01:28:57 2009 [notice] connection to router established
Mon Oct 12 01:28:57 2009 [notice] [0.0.0.0, port=5222] listening for connections
Mon Oct 12 01:28:57 2009 [notice] [0.0.0.0, port=5223] listening for SSL connections

* While registering user ~

1) Required SSL/TLS
2) Force old SSL (5223 port)

Please enable above two setting and uncheck “Allow plaintext auth unecrypted streams”

NOTE ~ While login first time (auto registration mode) make sure to check “Create this new account on the server” checkbox in pidgin (bottom)

** It works !!

Step 10] Init.d startup script for Jabberd2 and Mu-Conference –

root@laptop:~# /etc/init.d/jabberd2 start
Starting the Jabberd2 IM Server…
router 11095 | sm 11099 | s2s 11102 | c2s 11106 |mu-conf 11149
…
Done.
root@laptop:~# /etc/init.d/jabberd2 status

router – 11095 | sm – 11099 | s2s – 11102 | c2s – 11106 | mu-conf 11149
root@laptop:~#

* Now check network setting…

root@laptop:~# netstat -nlp

Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name

…..
[root@desktop ~]# lspci -n

03:00.0 Class 0200: 1969:1048 (rev b0)
…
…..
[root@desktop ~]#

* Make sure to download drivers for above  venderID & deviceId “1969:1048″….

Step 2] download and extract the source  –

First, download vendor* driver from here

ftp://ftp.hogchain.net/pub/linux/attansic/vendor_driver/l1-linux-v1.2.40.3.tar.gz

OR

How to configure TATA Indicom/BSNL/Reliance Broadband+ Netconnect ( EDVO usb modem ) on Ubuntu Linux

How to configure TATA Indicom/BSNL/Reliance Broadband+ Netconnect ( EDVO usb modem ) on Ubuntu Linux

By | | Comments 3 comments

Introduction ~

This article is about how to configure TATA Indicom,BSNL and Reliance Broadband+ Netconnect ( EDVO usb modem ) on Ubuntu Linux.

To configure Reliance,BSNL and Tataindicom epi valley usb modem please refer the following article ~

http://www.indiangnu.org/2008/tata-indicom-usb-modem-epi-valley-on-ubuntu-linux/

To configure Tataindicom,Reliance Huawei datacard refer the following article ~

http://www.indiangnu.org/2008/tata-indicom-datacard-huawei-cdma-on-linuxubuntu/

** EVDO ?

EVolution-Data Optimized (EVDO) is a telecommunications standard for the wireless transmission of data through radio signals, typically for broadband Internet access. It uses multiplexing techniques including code division multiple access (CDMA) as well as time division multiple access (TDMA)
to maximize both individual user’s throughput and the overall system throughput. It is standardized by (3G) 3rd Generation Partnership Project 2 (3GPP2) as part of the CDMA2000 family of standards and has been adopted by many mobile phone service providers around the world – particularly those previously employing CDMA networks.

How to configure Reliance Broadband+ Netconnect –

Step 1] Mount USB file system to “/proc/bus/usb” –

root@laptop:~# ls  /proc/bus/usb/
root@laptop:~#

* It shows that usbfs is not mounted on “/proc/bus/usb”. To mount run following command….

root@laptop:/var/src/usb_modeswitch-1.0.5# mount -t usbfs  none /proc/bus/usb
root@laptop:/var/src/usb_modeswitch-1.0.5# ls /proc/bus/usb/
001  002  003  004  005  006  007  devices
root@laptop:/var/src/usb_modeswitch-1.0.5#

Step 2] Get the status of Reliance Broadband+ USB device ~

* lsusb list USB devices connected to PC as well as information about USB buses in the system and the devices connected to them.

* Output before connecting Reliance Broadband+ Netconnect usb modem –

root@laptop:~# lsusb
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
…..
root@laptop:~#

* Let’s connect Reliance Broadband+ Netconnect! usb modem –

root@laptop:~# lsusb
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 004: ID 19d2:fff5
Bus 005 Device 003: ID 08ff:2580 AuthenTec, Inc. AES2501 Fingerprint Sensor
…..
root@laptop:~#

* Bus 005 Device 004: ID 19d2:fff5  – This shows that the Reliance (EVDO) usb device is detected with Vendor_id  19d2  and product_id fff5

root@laptop:~# cat /proc/bus/usb/devices

*** Reliance Broadband+ EVDO USB is detected as “USB storage device” as shown above…

Step 3] How to use Reliance Broadband+ Netconnect as USB Modem –

To use Reliance Broadband+ usb as USB Modem. We need to switch the usb mode of this device with the help of “usb_modeswitch” tool.

Download ~ http://www.draisberghof.de/usb_modeswitch/usb_modeswitch-1.0.5.tar.bz2

Help – http://www.draisberghof.de/usb_modeswitch/

* Download and extract the “usb_modeswitch” –

root@laptop:/var/src# wget -c  http://www.draisberghof.de/usb_modeswitch/usb_modeswitch-1.0.5.tar.bz2

root@laptop:/var/src# tar xvfj usb_modeswitch-1.0.5.tar.bz2

* Now compile and install –

root@laptop:/var/src/usb_modeswitch-1.0.5# gcc -l usb -o usb_modeswitch usb_modeswitch.c
root@laptop:/var/src/usb_modeswitch-1.0.5# make install
mkdir -p /usr/sbin
install ./usb_modeswitch /usr/sbin
mkdir -p /etc
install –mode=644 ./usb_modeswitch.conf /etc
root@laptop:/var/src/usb_modeswitch-1.0.5#

**** Now configure USB mode switching –

a) Edit configuration file “/etc/usb_modeswitch.conf” –

Just search for vendor and product id eg (19d2 and fff5) in config “/etc/usb_modeswitch.conf” file….
This file contains most of the details. I choose following setting and that work’s for me

root@laptop:~# cat  /etc/usb_modeswitch.conf

###################
# ZTE AC8710
#

DefaultVendor=  0x19d2
DefaultProduct= 0xfff5

TargetVendor=   0x19d2
TargetProduct=  0xfff1

MessageContent=”5553424312345678c00000008000069f030000000000000000000000000000″

root@laptop:~#

b) Now run “usb_modeswitch” command to switch the mode of USB device –

root@laptop:~# usb_modeswitch -c /etc/usb_modeswitch.conf

Step 4] Load “usbserial” module

* Remember in Ubuntu 09.04 the “usbserial” is buildin kernel. To load that module we need to modify “grub.conf” or “menu.lst” GRUB config file

root@laptop:~# cat /boot/grub/menu.lst

title        Ubuntu 9.04, kernel 2.6.28-11-generic

How to build RPM of PHP for apache with mpm-worker

How to build RPM of PHP for apache with mpm-worker

By | | Comments 0 Comment

In my last post, we have seen how we build rpm package for apache with default mpm-worker now it this tutorial we will see how we build rpm of php that can work with apache with mpm-worker.

Download php source rpm from mirror.centos.org

http://mirror.centos.org/centos-5/5.2/os/SRPMS/php-5.1.6-20.el5.src.rpm

To resolve the dependancies to build RPM package for PHP installing the require some lib packages

[root@testbed2:/tmp]# yum install bzip2-devel curl-devel gmp-devel aspell-devel libjpeg-devel libpng-devel pam-devel openssl-devel sqlite-devel pcre-devel krb5-devel libc-client-devel mysql-devel postgresql-devel unixODBC-devel libxml2-devel net-snmp-devel libxslt-devel libxml2-devel ncurses-devel gd-devel freetype-devel

install source rpm using
[root@testbed2:/tmp]# rpm -i php-5.1.6-20.el5.src.rpm

[root@testbed2:/tmp]# cd /usr/src/redhat/SPECS

vi php.spec and find “%configure” (without quote) where you can put the “–enable-maintainer-zts \” (without quote)

then rebuild rpm using below command

[root@testbed2:/usr/src/redhat/SPECS]# rpmbuild -bb php.spec

after creating rpm you will find all rpm in /usr/src/redhat/RPMS/{your arch folder} folder
in my condition the rpm’s in /usr/src/redhat/RPMS/x86_64

now change the httpd mpm to worker

[root@testbed2:/usr/src/redhat/X86_64]# /etc/init.d/httpd stop

edit file /etc/sysconfig/httpd

just uncomment the HTTPD=/usr/sbin/httpd.worker line

save and exit then start the httpd service

Now install php rpms from /usr/src/redhat/RPMS/{your arch folder}

[root@testbed2:/tmp]# /etc/init.d/httpd start
[root@testbed2:/tmp]# httpd -V
[root@testbed2:/tmp]# php -v

This is the way that I have done this. I know people are many way and good idea’s to do this.

So keep commenting that update that the things.

How to build rpm for http with mpm worker (on x86_64)

How to build rpm for http with mpm worker (on x86_64)

By | | Comments 0 Comment

Guy’s since I started working on apache, I found that apache is most use ful web technology over network.
Everyone knows that (multi-processing module) MPM Prefork is default included in apache rather than MPM Worker.

MPM Prefork = This Multi-Processing Module (MPM) implements a non-threaded, pre-forking web server that handles requests in a manner similar to Apache 1.3. It is appropriate for sites that need to avoid threading for compatibility with non-thread-safe libraries. It is also the best MPM for isolating each request, so that a problem with a single request will not affect any other.
MPM Worker = This Multi-Processing Module (MPM) implements a hybrid multi-process multi-threaded server. By using threads to serve requests, it is able to serve a large number of requests with fewer system resources than a process-based server. However, it retains much of the stability of a process-based server by keeping multiple processes available, each with many threads.

More information is available on apache.org manuals

http://vr-zone.com/manual/en/mod/prefork.html
http://vr-zone.com/manual/en/mod/worker.html

On RPM based OS’s, apache is default with MPM-Prefork so we will build apache RPM (with default MPM-worker) for our own, don’t know this will be useful or now but will have know everyone with this 🙂

Download the source rpm packages from http://mirror.centos.org

[root@testbed2:/tmp]# wget http://mirror.centos.org/centos-5/5.3/os/SRPMS/httpd-2.2.3-22.el5.centos.src.rpm

install http source rpm

[root@testbed2:/tmp]# rpm -ivh httpd-2.2.3-22.el5.centos.src.rpm

[root@testbed2:/tmp]# cd /usr/src/redhat/SPECS

edit httpd.spec with vi editor

[root@testbed2:/usr/src/redhat/SPECS]# vi httpd.spec

find the –with-mpm and enter below config parameter under the –with-mpm

–enable-headers –enable-uniqueid \
–enable-deflate \
–enable-mime-magic \
–enable-so –enable-rewrite \
–enable-http \
–enable-log-config \
–with-libexpat=built-in \

Now find the “mpmbuild prefork”  and replace with “mpmbuild worker”

Now find the “mpmbuild worker” and replace with “mpmbuild prefork”
(you may find this, just few line below)

and most important thing is that you have to comment some lines i.e. (./prefork/httpd -l | grep -v prefork > prefork.mods to done)

find and comment from “./prefork/httpd -l | grep -v prefork > prefork.mods” to “Done” (i.e. just total 8 lines)

Now time to build http with mpmworker for that some dependancies are comes that we will resolve using yum

yum install xmlto db4-devel expat-devel libselinux-devel  apr-devel apr-util-devel pcre-devel openssl-devel distcache-devel

[root@testbed2:/usr/src/redhat/SPECS]# rpmbuild -bb httpd.spec

you have wait for few min and watch whats going on screen ……

your rpm build is created and placed into /usr/src/redhat/RPMS/x86_64

Now install the packages and check with ‘httpd -V’

N’joy
