After some terrible actions, I had to reinstall my Fedora (was 20, became 22). Unfortunately, I was unable to made mysqldump, so I backuped /var/lib/mysql folder. Now, I'm trying to put in on the fresh install and it can't start mariadb.service. Probably, the problem in mysql.sock. If it is also copied - systemctl show messages:
mysql.sock exists
No process is using /var/lib/mysql/mysql.sock, which means it is a garbage, so it will be removed automatically
But nothing happens. Also, mariadb simply failed to start and I can't find out the reason. But if I delete mysql.sock it definitely says, that file is missing and errored. So, how I can restore my database, at least data? Or... Does exist any other solution to make this all stuff work?
journalctl? After restoring your backup, did you set file contexts correctly? (Try runningtouch /.autorelabeland rebooting.)
