systemctl start mysqld

and run

mysql_secure_installation

firewall-cmd --add-port=3306/tcp --permanent && firewall-cmd --reload

if needed for phpMyAdmin Verify security with

—enter your password and expect a prompt like \"mysql>\" On Hetzner Fedora VPS this ensures a locked-down database protecting against unauthorized access while maintaining uptime for web hosting
