i was just checking somethings and noticed mysqld is not running in parallels power panel control panel...but my websites on the server were all working fine, which use mysql databases...so really strange

So i tried to restart mysqld but got errors and can't restart and now all my websites are all offline now saying error connecting to database.

logged in as root and tried

/etc/init.d/mysqld start

and got this error

ERROR! Manager of pid-file quit without updating file

What do i do next?

What do i do? Please help!

  • look at MySQL log, normally in /var/log/mysql.log or /var/log/mysql/mysql.log

Is your hard drive out of space? Run:

df -h

Or try renaming /etc/my.cnf to /etc/my.cnf.old and it'll rebuild a new my.cnf.

It may also be in the /etc/mysql/my.cnf directory


After chatting, we figured out that mysql was still running. Apparently, some people have reported this error message is caused when mysql doesn't shut down properly, but thinks it's shut down.

So we ran

ps aux | grep mysqld

To see running processes, then,

kill 23445 34255

To stop the processes...

Then /etc/init.d/mysqld start

to start the server back up.
