120825 15:07:10  mysqld ended

----------------------------------------------------------------------------------------------------------------------------------------------------
I checked all services but Mysql wont work:

[root@sulat ~]# /etc/init.d/mysqld status
mysqld is stopped
[root@sulat ~]# /etc/init.d/mysqld start
Timeout error occurred trying to start MySQL Daemon.
Starting MySQL:                                            [FAILED]

-----------------------------------------------------------------------------------------------------------------------------------------------------
Here's my /etc/my.cnf configuration

[mysqld]
#bind-address            = 127.0.0.1

[mysqld_safe]

pid-file    = /var/run/mysqld/mysqld.pid
-------------------------------------------------------------------------------------------------------------------------------------------------------

I think this is the error:

[root@sulat log]# mysqladmin version
mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)'
Check that mysqld is running and that the socket: '/var/lib/mysql/mysql.sock' exists!

Thank you in advance for those will help me...
