I was not using my machine for a while. After turning it on again and updating everything I saw, that the status of MySQL was "red" even if the service was still started. Logging in to Management Site was not possible, too. So I reinstalled it, but this didn't solve the issue. Then I completely reinstalled my OMV and MySQL was working for a few hours. I run a new search with Kody and afterwards MySQL stopped again.
Today I tried purging the package (like I read in several topics here), reinstalling it several times and in the end deleted the MySQL user.
Now if I reinstall the package the MySQL user is still missing. But all in all I don't think that reinstalling the package now would solve the issue.
Could you please advice how to get MySQL installed again (with the user) and up and running? Which logs do you need from me?
Thanks in advance.
Edit: Error message by starting the plugin
Failed to execute command 'export LANG=C; invoke-rc.d 'mysql' stop 2>&1': Stopping MySQL database server: mysqldWarning: World-writable config file '/etc/mysql/conf.d/pw.cnf' is ignored failed! invoke-rc.d: initscript mysql, action "stop" failed.
Edit2 (27.12.16): I did now again a complete fresh install of OMV, but im still not able to start MySQL. Could there be something wrong with privileges/ACL?
So I deleted my old database folder and its content and tried starting from scratch but even with empty folders mysql won't start up.
