If you see Active: active (running) in the output, this means everything went well. If you’re having trouble at this point, make sure to carefully read the previous instructions and make sure your Webmin repository was properly set up. Note: Webmin is accessible via port 10000. If you have a firewall, you need to allow Webmin's port through the firewall-cmd firewall,
