Hello @mohammadreza

Can you let us know which command you are executing to start MariaDB, try

/scripts/restartsrv_mysql
or
From WHM, restart and check the status

You can check the error log file mentioned in my.cnf to know the exact error.

Some more details is needed to know this.

Regards,

Thanks, @HostNoc for trying to assist here. @mohammadreza What if anything is noted in the mysql error logs? What firewall are you running on the server?

This indicates that you've set the max_open_files and max_connections in the mysql conf at /etc/my.cnf but it does not indicate the issue with it starting. Can you please include the log messages when you attempt to restart the service. If you're unsure where the log file is you can find it listed in the mysql configuration file.
