MariaDB: Shutdown right after start

So when i try to start mariadb this happens:

Job for mariadb.service failed because a timeout was exceeded.
See "systemctl status mariadb.service" and "journalctl -xe" for details.

systemctl status mariadb.service shows this:

    * mariadb.service - MariaDB database server

Either I am blind or there just isn't any error and mariadb is just not working. Maybe one of you guys have an idea. Thanks.

Edit:

I found a "solution" for now, mariadb is shutting down because of a timeout when starting, so for now I set the timeout to 0. For now this solution is enough but there must be a real solution.

Please note that since 10.1.10, MariaDB uses systemd to start the service. The /etc/init.d/mysql script is no longer used, so MYSQLD_STARTUP_TIMEOUT has no effect.

You need to find your mariadb.service file. In our case, it did not contain a timeout so the MariaDB default was being used. Just add /etc/systemd/system/mariadb.service.d/override.conf file, and put in it:

[Service]
TimeoutStartSec = 0

In the [Service] section, and it will never time out. After create the file:

# systemctl daemon-reload
# systemctl restart mysql.service
