ERROR! MySQL manager or server PID file could not be found!

Some times you may get mysql error on the page. And on checking the status of the mysql, if you are getting following error 

# /etc/init.d/mysqld status
ERROR! MySQL manager or server PID file could not be found!

Then the Fix is below.

Check the file /etc/my.conf and see any thing mentioned as " basedir= ". If nothing mentioned in the file, by default it would be /var/lib. Then, check the permission for /var/lib/mysql and make sure all are having user and group " mysql ". If not do

#chown -R mysql.mysql /var/lib/mysql

Then, restart mysql

#/etc/init.d/mysql restart

This should fix the issue.
