When trying to start MySQL server, are you facing this error :

“Timeout error occurred trying to start”

Check for the MySQL logs to see if you can track something.

# /var/log/mysqld.log or /var/lib/mysql/hostname.err

( whichever is the log location ) and see if you can trace :

==============

[ERROR] /usr/libexec/mysqld: Disk is full writing ‘ (Errcode: 122). Waiting for someone to free space… Retry in 60 secs
…………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………..

==============

Check for the server disk-space # df -h.

Clear any unwanted logs/files and make sure there is enough free space and restart your service.
