Step 8: Enter the domain name in the server name section.

Now, you’ve created the Webmin virtual host.

How to Install Webmin on an Ubuntu Server or Debian-Based Server

In the first section, we discussed installing Webmin on a REHL-based VPS. Now, we will show you how to install Webmin on an Ubuntu or Debian-based server.

First, you need to install the dependency packages by typing the following command:


sudo apt install software-properties-common apt-transport-https -y

Add the Webmin repository and the GPG key.


sudo wget -q http://www.webmin.com/jcameron-key.asc -O- | sudo apt-key add -


sudo add-apt-repository "deb [arch=amd64] http://download.webmin.com/download/repository sarge contrib"

Finally, install Webmin:


sudo apt install webmin -y

If you have a firewall, you should allow it by using this command:


sudo ufw allow 10000/tcp

That’s it! You successfully installed Webmin on your server. The default username is root, and the password is your current root password.

Now, you need to open your web browser and navigate to the following address:

https://localhost:10000/

Sometimes Debian or Ubuntu distributions do not allow users to log in by the root user and its pass. In that case, you must enter sudo for the username.

After you log in, you can configure your web server according to your needs and goals.
