I'm running only into problems the last few days. I Installed mariadb on my Ubuntu 16.04 lts server. apt-get install mariadb-server maridb-client comment out the bind addres in vi /etc/mysql/mariadb.conf.d/50-server.cnf restarted it and it worked. Then I stopped it. After that it won't start again. systemctl status mysql.service output: mysql.service - LSB: Start and stop the mysql database server daemon Loaded: loaded (/etc/init.d/mysql; bad; vendor preset: enabled) Active: failed (Result: exit-code) since Fri 2017-03-31 14:42:44 CEST; 10s ago Docs: man:systemd-sysv-generator(8) Process: 4422 ExecStart=/etc/init.d/mysql start (code=exited, status=1/FAILURE) Mar 31 14:42:44 tmysql1 /etc/init.d/mysql[4904]: 0 processes alive and '/usr/bin/mysqladmin --defaults-file=/etc/mysql/debian.cnf ping' resulted in Mar 31 14:42:44 tmysql1 /etc/init.d/mysql[4904]: [61B blob data] Mar 31 14:42:44 tmysql1 /etc/init.d/mysql[4904]: error: 'Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2 "No such file or directory")' Mar 31 14:42:44 tmysql1 /etc/init.d/mysql[4904]: Check that mysqld is running and that the socket: '/var/run/mysqld/mysqld.sock' exists!

The /var/log/mysql/error.log has only entrys until the stop, nothing after that.
According to the ERRORs some mysql-tables are missing. You can also check, if mysql is not running with ps -ef|grep mysql
yeah I know but I can't create because I can't start the service them. in /var/log/syslog I have: Apr 1 08:51:51 tmysql1 mysqld: 170401 8:51:51 [ERROR] Can't open the mysql.plugin table.

I configured it like it's in https://www.howtoforge.com/tutorial...l-pureftpd-bind-postfix-doveot-and-ispconfig/
kinda solved it... added it to repo apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0xF1656F24C74CD1D8 add-apt-repository 'deb [arch=amd64,i386] http://sgp1.mirrors.digitalocean.com/mariadb/repo/10.1/ubuntu xenial main' run apt-get update && apt-get upgrade purged it apt purge mariadb-server mariadb-client apt autoremove installed it again apt-get install mariadb-server mariadb-client now it works. But if I have to do this everytime I want to install a server with mariadb it will be a hassle. Google is full of similar errors for mysql and ubuntu 16.04 so is it broken that much. The mysql-server has evem a hard dependency for apparmor.
nope not working... now it starts and runs but it still not work. when I try to use mysql (mysql -u root -p) I get another error ERROR 1524 (HY000): Plugin 'unix_socket' is not loaded
solved it.... nedded to revert to my clean system setup snapshot and did like instructed on https://www.linuxbabe.com/mariadb/install-mariadb-10-1-ubuntu14-04-15-10#disqus_thread Now it works.... for now at least.
