If you ever run into a situation that MariaDB (mysql) isn't running and doesn't want to start anymore, the script mysql_repair.sh can save your day.

First of all, verify that mysqld is indeed not working by using go ps, which will show the following if the process is offline.

If indeed offline, the mysql_repair.sh script can be run, which will troubleshoot and try to fix the situation. The error log can be viewed as well, which is found at /var/opt/mysql/<hostname.domain>.err.

Once the repair script is finished the daemon will be started automatically and other demons that depend on it will be started as well by yce_psmon.

The script is located in: /opt/yce/system/mysql_repair.sh
