mysql service fails to start/hangs up - timeout (Ubuntu, MariaDB)

Question

I set up my first Ubuntu Server with Ubuntu 16.04, nginx, php7.0, MariaDB, nextcloud and external DynDNS using this tutorial here: Install Nextcloud 9 on Ubuntu 16.04

Answer 1

This is what worked for me:

The correction didn't work for me.

$ sudo aa-complain /usr/sbin/mysqld Setting /usr/sbin/mysqld to complain mode.

ERROR: /etc/apparmor.d/usr.sbin.mysqld contains no profile So I disabled the profile (with aa-disable which seems to be equivalent to plutocrat's solution)

$ sudo aa-disable /usr/sbin/mysqld Disabling /usr/sbin/mysqld. I disabled mysqld-akonadi and mysqld-digikam as well.

An apparmor reload was not enough, so I had to reboot and mariadb started perfectly well.
