Apply config don't work first time

[scottwilkerson]

Yes, there was not /var/log/mariadb/mariadb.log on DB server, I copied "log-error=/var/log/mariadb/mariadb.log" in first part of my.cnf , after "[mysqld]". Then restarted mariadb.services, the file mariadb.log was created.

Got it.

Glad you got it sorted out.
