1] Watchdog installation on Linux Plesk Server –
Introduction – Plesk is one of the leading control panel for Web hosting on both Linux and Windows Server. This article only focus on Plesk Server on Linux platform. Default setting for Plesk control panel is stored in file “/etc/psa.conf” from where you can find out the document root of Plesk server and other default setting etc…
Problem 1) when trying to login to Plesk as an admin user, a popup says “Access Denied”
Reason :- Plesk has an built-in security feature with account logins (basically only 3 login attempts are allowed). If you enter wrong user name or password 3 times, the server will lock you out. Plesk store MySQL admin or admin user’s password in file “/etc/psa/.psa.shadow”
root@arunbagul:~# mysql -u admin -p
Welcome to the MySQL monitor. Commands end with ; or \g.
Type ‘help;’ or ‘\h’ for help. Type ‘\c’ to clear the buffer.
mysql> use psa;
mysql> DELETE FROM lockout WHERE login = ‘admin’;
Enjoy you Plesk Server!!
