Webmin is a powerful web-based server control panel designed to simplify Linux system administration. It provides an easy-to-use interface for managing various aspects of a server, including user accounts, web servers, databases, and more. If you want to install Webmin on Ubuntu 22.04, this tutorial will guide you through the process.

Prerequisites

• An Ubuntu 22.04 server
• A user account with sudo privileges

Step 1: Update the System

Before installing any new software, it’s good practice to update your system to ensure you have the latest packages installed. Open a terminal and run the following commands:

sudo apt-get update
sudo apt-get upgrade

Step 2: Add the Webmin Repository

The Webmin repository is not included in the default Ubuntu repositories, so you’ll need to add it manually. This involves adding the Webmin GPG key and updating the package sources.

1. Add the GPG key

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

This command downloads the Webmin GPG key and adds it to your system.

2. Add the Webmin repository

sudo sh -c 'echo "deb https://download.webmin.com/download/repository sarge contrib" >> /etc/apt/sources.list'

This command adds the Webmin repository to your /etc/apt/sources.list file.

3. Update the package list

sudo apt-get update

This updates the package list to include Webmin from the newly added repository.

Step 3: Install Webmin

Once the repository is added, you can install Webmin with a simple command

sudo apt-get install webmin

This command will download and install Webmin along with any necessary dependencies.

Step 4: Access Webmin

After installation, you can access Webmin using a web browser. By default, Webmin listens on port 10000.

https://server_ip_address:10000

Step 5: Log in to Webmin

To log in, use your Ubuntu system credentials. If your user account has sudo privileges, it will have administrative access in Webmin. If you need to change the Webmin password or add a different user, you can run

sudo /usr/share/webmin/changepass.pl /etc/webmin/htusers <username>

Replace <username> with the actual username.

Conclusion

You now have Webmin successfully installed and running on your Ubuntu 22.04 server. With Webmin, you can manage your server’s services, configuration files, and user accounts through an intuitive web-based interface, significantly simplifying server administration tasks.
