How To Install Webmin on Debian 12

In this tutorial, we will show you how to install Webmin on Debian 12. For those of you who didn’t know, Webmin, a versatile web-based system administration tool, redefines the way Linux servers are managed. With its graphical interface, even those without a profound command-line understanding can comfortably navigate complex administrative tasks. Embrace the advantages of Webmin, from simplifying user management to configuring firewalls with finesse.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you step-by-step install Webmin on a Debian 12 (Bookworm).

Prerequisites

• A server running one of the following operating systems: Debian 12 (Bookworm).
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• SSH access to the server (or just open Terminal if you’re on a desktop).
• An active internet connection. You’ll need an internet connection to download the necessary packages and dependencies for Webmin.
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Webmin on Debian 12 Bookworm

Step 1. Before we install any software, it’s important to make sure your system is up to date by running the following apt commands in the terminal:

sudo apt update
sudo apt install curl gpg gnupg2 software-properties-common apt-transport-https lsb-release ca-certificates

This command will refresh the repository, allowing you to install the latest versions of software packages.

Step 2. Installing Webmin on Debian 12.

• Method 1: Install Webmin using APT Repository.

First, you need to add the Webmin repository to your Debian 12 system. To do this, open the terminal and run the following command:

echo "deb http://download.webmin.com/download/repository sarge contrib" | sudo tee /etc/apt/sources.list.d/webmin.list

Next, you need to add the Webmin GPG key to your system to verify the packages. Run the following command to download and install the key:

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

Once you have added the repository and key, update the package list by running the following command:

sudo apt update

Finally, install Webmin by running the following command:

sudo apt install webmin

• Method 2: Installing Webmin from the Webmin Website.

First, download the latest Webmin package from the official website by running the following command:

wget http://prdownloads.sourceforge.net/webadmin/webmin_2.101_all.deb

Next, install the required dependencies by running the following command:

sudo apt install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl apt-show-versions python

Once the dependencies are installed, install Webmin by running the following command:

sudo dpkg -i webmin_2.101_all.deb

Step 3. Configuring Firewall Rules

Empower Webmin to operate seamlessly by aligning your firewall settings with its requirements. Choose between iptables or UFW to ensure Webmin’s accessibility:

• Using iptables:

sudo iptables -A INPUT -p tcp --dport 10000 -j ACCEPT
sudo iptables-save | sudo tee /etc/iptables/rules.v4

• Using UFW:

sudo ufw allow 10000/tcp

Step 4. Accessing Webmin Web Interface.

After the installation is complete, you can access the Webmin web interface by opening a web browser and navigating to https://your_server_ip:10000. You will be prompted to enter your system username and password to log in.
