Manager of pid-file quit without updating file. http://linux.bgsnow.com/starting-mysql-error-manager-of-pid-file-quit-without-updating-file.php http://linux.bgsnow.com/starting-mysql-error-manager-of-pid-file-quit-without-updating-file.php#comments Sat, 14 Nov 2009 21:11:40 +0000 admin http://linux.bgsnow.com/?p=195 I got that nasty error after moving around different directories in /var/lib/mysql:

root@server:/var/lib/mysql# /etc/init.d/mysql start

Starting MySQL. ERROR! Manager of pid-file quit without updating file.

There were all kind of suggestions about it on the net, most of which had something to do with incorrect shutdown or incorrect permissions for the pid file.

One of the suggestions reminded me to read the mysql error log :) Here is what the error log said:

Obviously I have forgotten to move back the mysql directory which is responsible for the database for all privileges, databases and so on :)  So moving it back along with the rest of the core files solved the problem:

root@server:/var/lib/mysql# mv ../mysqlOLD/* ./

mv: overwrite `./host.server.bgsnow.com.err'? y

mv: overwrite `./ibdata1'? n

mv: overwrite `./ib_logfile0'? n

mv: overwrite `./ib_logfile1'? n

mv: overwrite `./mysql-slow.log'? y

root@server:/var/lib/mysql# /etc/init.d/mysql restart

Shutting down MySQL. SUCCESS!

Starting MySQL. SUCCESS!

Thus if you have similar problems, the first thing is to check the MySQL error log and don't believe the misleading error about the PID :)
