Your MySQL server is down
please add it to autostart and/or check why it wasn't started

Hi, i am install OM2 on CentOS in VMware. Everything is OK until i restart server.
I get error :

The server is not yet completely initialized. Please try again in a couple of seconds.
If this message persists for several minutes contact your Sys-Administration.

I'm sure mysql info is correct.

I run /ect/init.d/restart or /ect/init.d/start or /data/openmeeting/red5.sh, but OM don't run.

This is red5-debug:
