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:

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

I logged into the server using SSH and it said my server needed to have a reboot. So I logged into my plesk panel and hit the restart server button. After the reboot... MySQL/MariaDB doesn't start anymore. I'm getting errors that seem to indicate database corruption. I would really appreciate some advice on how to fix this issue. I don't encounter this problem very often.
Some sites have said to reinstall the database. Other places have said to use innodb_force_recovery. I do not have any backups (I know, Shame on me. This is a personal server.). I DO have a copy of the /var/lib/mysql directory. Though the copy is taken AFTER the database stopped booting.

I'm trying to change where mysql uses for temporary tables. I have a drive mounted at /media/E, and I've created a directory owned by root with permissions drwxrwxrwxt at /media/E/tmp.
I have changed tmpdir in /etc/mysql/mysql.conf.d/mysqld.cnf to point to this directory.
I then restart mysql like so:
username#grey:/media/E/tmp$ sudo service mysql restart
Yielding the following error:
Job for mysql.service failed because the control process exited with error code.
See "systemctl status mysql.service" and "journalctl -xe" for details.

MySQL is armored by AppArmor, which does not allow writing freely to /media/E/tmp. To remedy the situation, you can edit the /etc/apparmor.d/abstractions/user-tmp and add the /media/E/tmp there appropriately; for me the extra lines
owner /media/E/tmp/** rwkl,
/media/E/tmp/ rw,
Mysql status fails every few hours, I also checked the buffer size, no problem with them and

I tested this project on a server with 2 GB of RAM, but it failed on a server with 8 GB of RAM.
Consider these changes to your my.cnf [mysqld] section
innodb_buffer_pool_size=4G
and REMOVE to allow defaults to work for improved performance
read_rnd_buffer_size
read_buffer_size
sort_buffer_size
to reduce RAM footprint.

Today at around 6:23 UTC my Ubuntu Server 16.04 in Amazon EC2 made an automated apt update. From around this time my MySql server refuses to start.
At first he told me the apparmor config was wrong (like here: mysql wont start Ubuntu 16.04.2 x64) which i fixed.
Now when I try to start the mysql service like this:
:~$ sudo /etc/init.d/mysql start

failed because the control process exited with error code. See "systemctl

On the one hand I have seen that the the error.log tells me to run run mysql_upgrade which i cannot do because the database itself is not running.
The [ERROR] Fatal error: Can't open and lock privilege tables: Table 'mysql.user' doesn't exist should be fixed by an initilize command onto the service which wont work either because the service itself is not running.
I do not have a single clue what to do next. My personal best Idea for now would be to reinstall the MySql server and copy beforehand the /var/lib/mysql/mysql and the /etc/mysql directories to insert them later as a backup.
I hope anyone of you has heard something about the problem or has any kind of idea what to do. Preferably while keeping my Data.
I hope, I provided all information you need. If you need any more, just ask.
Thanks a lot in advance!
