    What is the exact error being returned by MySQL when trying to restart it? Also, do you have any entries in /usr/local/cpanel/logs/error_log or in /var/lib/mysql/hostname.err log when you try to restart it? Please replace hostname.err with the server's full hostname for that log file.

    I have tried to force a cpanel update, I have tried to force a mysql update. I also change the reset the root password to the server as well as tried to reset the mysql password.

    One tip I saw was to move and rename /var/lib/mysql to /var/lib/mysql.bak and for an mysqlupdate, then I freaked when all my databases disappeared. So I moved the mysql.bak to mysql


    Here is the error message:
    Starting MySQL. ERROR! Manager of pid-file quit without updating file.

    I just restarted my server and here is what is in the /usr/cpanel/log/error_log file:

    Did you make a full backup of MySQL or do you have a backup of MySQL prior to the password change? Right now, the issue isn't the password change but that InnoDB ib_logfiles don't match the ibdata content, which indicates a crash. It's pretty difficult to fix InnoDB corruption, so restoring from a backup would be preferred.

    I am leery of providing any recommendations for InnoDB recovery, since you can majorly mess up your databases if done incorrectly. It would be better to have your datacenter, NOC or provider help with any corruption, or to hire someone to fix it if you do not have sound backups.

    Also, always make backups for MySQL especially when using InnoDB before stopping it, restarting it, changing the password, or upgrading it. I've seen too many instances of InnoDB corruption preventing MySQL to restart, and that is exactly what you are showing right now as the issue.

    I do not have full backups of each of the databases for the various sites on the server. I could check with the NOC to see if they have a backup of the VPS server from the last day and use that to restore. could I take the databases from the /var/lib/mysql directory and backup those and use those after a reinstall?

    You cannot use the existing data in /var/lib/mysql because that data contains corrupted InnoDB data. Please contact your NOC about any VPS backups that exist. You will need the backup to be before the password was changed. You might even want to find out if they have multiple days of backups in case the corruption existed and wasn't apparent until the MySQL restart.

    Thanks. I am using Wordpress for most of my sites. I use the db-manager plugin for each, and that does a weekly backup of the sites and saves those .sql files. That might be the worse case scenario.

    Also I would like to say that once I did the mv /var/lib/mysql to mysql.bak and did a force update of mysql (when I saw all my db where gone) mysql still did not restart. Does that make a difference? Should it have started?

    MySQL would not restart on moving /var/lib/mysql to /var/lib/mysql.bak unless you created /var/lib/mysql with mysql:mysql ownership and ran /scripts/mysqlup --force, since moving the folders with only a restart doesn't recreate MySQL to exist.

    The NOC does not have any backups. So, can you tell me what I need to do to try and get this working again.

    Once I have mysql working again can I use one of the previous databases (one at a time) to see if it has problems which cause mySQL not to start, if so I can remove it and them move to the next one. Maybe I get lucky and fine only one or two that have issues and the others are good?

    I can't believe that this all happened from just resetting the password in WHM...

    You can try disabling innodb to begin with and see if it starts up before moving anything. In your /etc/my.cnf file, put the following entry:

    Code:
    skip-innodb
    Then try to restart MySQL. If it starts up, then it was definitely InnoDB. Do you know which specific databases were using InnoDB?

    OK something buzzer has happened. MySQl started working again... Let me explain what I did. When I first got this VPS I setup the host name to use hostname.net (because I owned the .net version of my domain name). However I forgot that I no longer used that one so I would go into channel and change it to .com. I rebooted the server yesterday and it still came back with .net. and I had not gone to fix it again.

    However while waiting for you to reply I went into the VPS control panel and changed it, then I went into cpanel and changed it and verified the new hostname license.

    Then I noticed that mysql was working again.... coincidence?

    I also noticed that the general.log file within mysql is 2.3 GB. That to me seems large, is that okay or should I do something with that?

    Another update: in WHM it still shows mysql as down and I keep getting mysql failed @ Mon Mar 28 17:26:13 2011. A restart was attempted automagically.

    Glad that MySQL is now working, although it's strange there were InnoDB errors otherwise on startup attempts unless those were prior errors.

    At this point since MySQL itself is running, can you open up a ticket for us to troubleshoot this further? You can open one in WHM > Support Center > Contact cPanel or using the link in my signature. If you have a ticket ID after opening the ticket, please feel free to post it here.

    Of note, I've replied to the ticket. The issue with MySQL working itself was due to the password change not having properly changed likely due to the fact InnoDB corruption does still exist on that machine (and likely prevented a proper change previously). I had to do the following steps while keeping "skip-innodb" in /etc/my.cnf to get the MySQL root password properly changed:

    1. Stopped MySQL

    Code:
    /etc/init.d/mysql stop
    2. Started MySQL in safe mode with skip-grant-tables

    Code:
    mysqld_safe --skip-grant-tables &
    3. Went into MySQL command line:

    Code:
    mysql
    4. Reset password in MySQL command line for mysql table

    Code:
    mysql> \u mysql 
mysql> update user set password=PASSWORD("passwordhere") where User='root'; 
mysql> flush privileges; 
mysql> quit
    Of note, I've replaced the actual password used from /root/.my.cnf with a phony password. You can find your password by running a cat on /root/.my.cnf file if you don't know what it happens to be:

    Code:
    cat /root/.my.cnf
    5. Stopped MySQL from safe mode and started it

    Code:
    /etc/init.d/mysql stop
/etc/init.d/mysql start
    At that point, mysql command line did work without any further issues. I've kept the skip-innodb option in /etc/my.cnf due to the fact that commenting it out won't let MySQL start still due to the existing InnoDB engine table corruption.
