FIX - Another MySQL daemon already running with the same unix socket.

To start the MySQL service, you can remove '/var/lib/mysql/mysql.sock' and start the MySQL service again:

1. Remove the socket file:

   [root@server ~]# rm /var/lib/mysql/mysql.sock
   rm: remove socket `/var/lib/mysql/mysql.sock'? yes
   

2. Start the MySQL service:

   [root@server~]# service mysqld start
   Starting mysqld:                                           [  OK  ]
