Edit Miniserv File

After the installation process is complete, edit the Miniserv.conf file in the webmin directory. MiniServ itself is a web server file that helps the process of running Webmin. To open the miniserv.conf file run the following command.

vi /etc/webmin/miniserv.conf

When finished changing files, restart webmin to confirm file changes. Run the following command to restart webmin.

Open Port

Continue the process by opening port 10000, this is intended to open access to access your Webmin panel because Webmin uses port 10000 to access it. Use the following command.

firewall-cmd --zone=public --add-port=10000/tcp --permanent

Then use the command below to restart the firewall service to activate the open port that was just made.

firewall-cmd --reload
systemctl restart firewalld

Access Webmin

To check the success of installing Webmin, try accessing Webmin by entering http://your_ip_server:10000/ in your browser, for example http://192.168.0.6:10000/

If your installation was successful, the Webmin login screen will appear, as shown below.
