Using the wget command, import Webmin’s GPG key as shown

Step 3: Installing Webmin

You can now proceed to install the latest version of Webmin by running

sudo apt install webmin

At the end of the installation, the following message will be displayed confirming that you’ve successfully installed Webmin.

The Webmin service should start automatically. you can verify this using the command

If the service is not running, start and enable it to start on boot using the following commands’

# systemctl start webmin

# systemctl enable webmin

Sample output

Again, verify if the Webmin service is running

# systemctl status webmin

Additionally, you can confirm if Webmin is listening to its default port – Port 10000 – using the netstat command as shown

# netstat -pnltu

Sample output

Awesome! Webmin service is up and running normally. Now it’s time to set it up on a browser!

Step 4: Adjusting the firewall

Before finally setting up Webmin on a browser, you need to allow port 10000, which os Webmin’s port, on the firewall. To accomplish this run

# Sudo ufw allow 10000/tcp

Thereafter, reload the firewall and check the status of the firewall.

sudo ufw reload

sudo ufw status

Sample output

Step 5: Setting up Webmin on a browser

Open your favorite browser and browse your server’s URL as shown

https://your_server_ip_or_hostname:10000/

You will get a warning that the connection is not private. This is because the server does not have an SSL certificate installed to encrypt the connection on https protocol.

Nevertheless, we can still connect and move on. to do this, navigate at the bottom and click on the ‘Advanced‘ button.

Then click on ‘proceed to server-ip‘ link

This will take you to Webmin’s login page. Log in using your root credentials
