In order to do anything with your VPS or Dedicated we need you to open a support ticket with ...
- server/vps ip address
 - root password
 - admin user and password if root logins disabled
 - exactly what you need done ( e.g.g please reinstall and start mysql daemon )
 
If you want to investigate the issue further yourself first, we recommend:
- stop and kill the existing MySQL process completely
 - stop and kill the PHP intepreter and Apache
 - from SSH update operating system and control panel to the latest stable builds
 - turn off auto updates of o/s and cpanel software
 - try and start the service from SSH
 - examine the logs if the service doesnt start.
 
Common reasons for MySQLd not starting are ...
- stuck processes
- ps auxf and kill anything unnecessary or restart the vps/server - ownership/permissions
- check the owner and mode of the files - version mismatch
- turn off "auto update" of control panel software, check version compatibilities with the software authors - out of process handles
- see what else is running, you may need a higher specification machine to perform all the tasks - not enough memory
- upgrade the vps or request additional ram for your dedicated server - insufficient disk space
- upgrade the vps or request a new disk for your dedicated server
