What is Webmin?

Before getting into our guide, let’s take a look at what Webmin is and how it works? Webmin is a Perl-based system that runs its process and servers. The software is a web-based UI for system administration designed to work with Unix or Linux-based operating systems. For example, you can use Webmin in your LAN or MAN network, where Webmin lets you manage and communicate with all of your servers from one PC. The system also allows you to control multiple servers from each interface. You will need to install the Webmin client on your servers and access the control panel in your main system PC through any modern web browser. 

How to Access Webmin?

You can access your Webmin dashboard from any modern web browser. You can connect and control your servers through the dashboard, but make sure the client Webmin is installed on your server. There’re many ways of configuring your servers for logging in, but we highly recommend using SSL configuration to have a secure login in your servers. However, you can also use the TCP port for better security.

Step 1 | Install Webmin

Webmin can run on the previous server’s package, but it’s better to use Webmin on the latest server’s box. Therefore, you can check for the newest version by the following command:

sudo apt update

Step 2 | Add Webmin Repository 

Now after updating the package of your server, you need to install Webmin’s repository, which will be used for installing and updating the Webmin system. We achieve that by adding it to the /etc/apt/sources.list file.

Open the file in your favored editor. Here, we’ll use nano:

sudo nano /etc/apt/sources.list

At the bottom, add this command to add the repository in your server:

. . .
deb http://download.webmin.com/download/repository sarge contrib

Save the file and exit the editor. If you used nano, do so by pressing CTRL+XY, then ENTER.

Step 3 | Download the Webmin PGP

Next, you must add the PGP key to Webmin so that your system with the purpose of trusting the current repository. To achieve that, you must set up the gnupg1 bundle, which is GNU’s tool with the aim of secure connection and data storage.

Now, you need to download Webmin’s PGP key. Download it by using wget and add the key to your list of keys in that server:

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

Step 4 | Update the Package

After that, we need to use the update command again to update your current system list of packages with the intention to include the latest Webmin repository:

sudo apt update

Step 5 | Install the Webmin

Once the update is finished, you can then install the Webmin on your server. To install the Webmin, enter the command:

$ Sudo apt install Webmin

The system will automatically install all the resources and essential components themselves. If the installation gets successful, you’ll get the following display:

Webmin install complete. You can now login to https://Server-IP:10000
as root with your root password, or any user who can use sudo
to run commands as root.

Now, you’ve installed Webmin on your servers. You can now control and manage your servers through the Webmin web-based server dashboard. We highly recommend you to keep checking for updates in your Webmin server to make sure you’re running on the latest Webmin.

However, the process doesn’t end here. It would be best if you secured your Webmin servers by adding a valid certificate.
