Configuration Modification of MariaDB database storage path

Configuration Modification of MariaDB database storage path

MySQL is not running, but lock file (/var/lock/subsys/mysql) exists
This problem is generally caused by three reasons:
1: some files in the configuration are not authorized enough. Change all files involved in the configuration to mysql user permissions.
2: No pid for mysql running. rm-rf/var/lock/subsys/mysql. The default permission for recreating a new pid file is 660.
3: my. cnf configuration file is incorrect and needs to be modified again

Can't open and lock privilege tables: Table 'mysql. user' doesn' t exist
This problem occurs because there is no built-in database in the myql file to store. You can enter mysql_install_db.
Or change the database path to the default/var/lib/mysql directory.

The following is my mariadb configuration (from the database)
