MariaDB start failure resolution after modifying storage path

Modify the MariaDB path to the home path,

When executing systemctl start mariadb startup mariadb, error message:

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 View error details

[Warning] Can ' t create test file/home/data/mariadbdata/localhost.lower-testmariadb.service:main process exited, code=exited, status=1/failurefailed to start MariaDB 10.3.9 database server.

The problem is because MARIADB has no access to the home path

Workaround:

1. Turn off SELinux

2. Modify the storage path permissions,

Chown-r Mysql:mysql/home/mysql_datachmod-r 764/home/mysql_data

3. If your storage path is the path below home, then here's the point:

Vim/etc/systemd/system/mariadb.service.d/homedir.conf

Enter the following content

[Service] Protecthome=false

And then execute

Systemctl Daemon-reload

Restart MARIADB

Systemctl Start mariadb
