After trying to import a database I had problem starting mysql.

# service mysql start

Job for mariadb.service failed because the control process exited with error code. See “systemctl status mariadb.service” and “journalctl -xe” for details.

# systemctl status mariadb.service

InnoDB: Set innodb_force_recovery to ignore this error.

To be able to delete tables in the database I had imported to I needed to use innodb_force_recovery

# nano /etc/mysql/my.cnf

I added the following line under [mysqld] in my.cnf
innodb_force_recovery=1

# service mysql start

I then logged into PHPmyAdmin and drop the tables in the database.

# nano /etc/mysql/my.cnf

I removed the line
innodb_force_recovery=1

# service mysql restart

Now everything worked. But I have to figure out why the db I tried to import messed up mysql….
