Initially i was thinking the problem is with Ubuntu 18.04 mysql package. So i set up another fresh Ubuntu 18.04 server, installed MySQL 5.7 and it worked prefectly fine.

We need to tell AppArmour to allow MySQL to use /mnt/log/mysql folder for logging. To do this, edit file.

Added following to it.

Now restart AppArmor.

Now MySQL will work properly.
