Webmin is an open-source web control panel for administering Linux servers. It allows you to manage the system users, groups, disk quotas as well as install and configure web, ssh, ftp, email and database servers.

With Webmin, you can configure almost every aspect of the system.

In this tutorial, we’ll show you how to install Webmin on Debian 10, Buster.

Prerequisites

You’ll need to be logged in as root or user with sudo access to be able to install packages.

Installing Webmin on Debian

Installing Webmin on Debian Linux is a simple and easy process that takes only minutes. The package is available from the official Webmin repositories.

  1. First, update the package index and install the dependencies:

    sudo apt update
    sudo apt install software-properties-common apt-transport-https wget
  2. Import the Webmin GPG key using the following wget command and enable the Webmin repository:

    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"
  3. Once the repository is enabled, install the Webmin package by running:

    sudo apt update && sudo apt install webmin

    On successful installation, the following output will be printed:

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

    The Webmin service will start automatically.

That’s it! Webmin has been installed on your Debian Linux server.

Adjust the Firewall

By default, Webmin listens for connections on port 10000 on all network interfaces. If your server runs a firewall, you’ll need to open the Webmin port.

UFW users can open port 10000 by typing:

sudo ufw allow 10000/tcp

If you are using nftables to filter connections to your system, open the necessary port by issuing the following command:

nft add rule inet filter input tcp dport 10000 ct state new,established counter accept

Accessing Webmin Web Interface

Now that Webmin is installed on your Debian server, launch your web browser and type your server’s hostname name or public IP address followed by the Webmin port 10000:

https://your_server_ip_or_hostname:10000/

The browser will complain because the certificate is not valid. By default, Webmin uses an untrusted self-signed SSL certificate.

Login to the Webmin web interface using your root or sudo user credentials:

Once you log in, you will be redirected to the Webmin dashboard where you can see basic information about your system.

From here you can start configuring and managing your Debian 10 server as per your requirement.

Upgrading Webmin

To upgrade your Webmin installation when new releases are published, use the apt package manager normal upgrade procedure:

sudo apt update
sudo apt upgrade

Conclusion

Webmin is a web-based tool that allows you to manage Linux servers. To install Webmin on Debian Buster, simply enable the official Webmin repository and install the package.
