Dear Support,

My operating system which installed on my server is : CentOS 5.5


LOGs

The suggestion from those error messages is that the MySQL daemon is already running. If you type

# ps ax | grep -i mysql

at the command line what kind of output do you get? You could also try

# service --status-all | grep -i mysql

Also, whenever the MySQL daemon is stopped the mysql.sock file in the

/var/lib/mysql

directory isn't present.

You could also try running

# netstat -tulnp

to see what services are bound to which ports - the default MySQL port is 3306.

If the MySQL daemon appears to be running but isn't working then you may want to manually kill the process it's associated with, or (perhaps) manually delete the mysql.sock file - although I'm not sure what the effect of this would be so don't do this without seeking the opinion of a better informed person first as instability may result! Can you connect to MySQL from the command line, or through a web application like phpMyAdmin?
