Note: Installation can take a few minutes and will depend on your server speed. Once it is complete, you will see a message with your Webmin admin URL.
Step 2: Next, open Webmin in a browser, https:// ip-address here:10000
On CentOS 7, if the URL doesn‚Ç¨‚Ñ¢t work, it means that you need to open port 10000. You can do so by running this command: firewall-cmd --zone=public --add-port=10000/tcp --permanent firewall-cmd --reload
The Webmin Dashboard will open. The New Design of WebMin looks really nice.
