MySQL Daemon Failed to Start - centos 6

EDIT: Look at the checkmarked answer comments to get your issue solved.

Whenever I try to start the SQLD service I get MySQL Daemon Failed to Start. I infact tried to "start" the service by doing the following:

service mysqld start

Also

When I type: mysql

I get:

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

I know that there should be a mysql.sock file in that directory, so I create one. But the file just auto removes its self and I continue to get the error 2002.

I am also unable to log into PHPMyAdmin due to the error. I can access phpmyadmin page but when logging in I get: #2002 Cannot log in to the MySQL server

EDIT:

Here is my mysql.log file:

Try restarting apache sudo service httpd restart. Worked for me.
