Fix MySQL server problem on LINUX CENTOS web server

I am having some trouble with starting Mysqld on my VPS. It is a production server, so I need it up and running ASAP. On this server I normally allow run MySQL connections on port 3306 to other sites. Permissions seem ok, but maybe i am overlooking something. Below the logs. Who can help me with this?? 140402 17:51:07 mysqld_safe mysqld from pid file /var/run/mysqld/[login to view URL] ended 140402 17:55:32 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql 140402 17:55:32 [Warning] '--default-character-set' is deprecated and will be removed in a future release.
