Webmin is an open-source web control panel for administration of Linux servers. With Webmin you can manage the system users, groups, disk quotas as well as configure most popular services including web, ssh, ftp, email and database servers.
This tutorial explains how to install Webmin on Debian Linux 9.
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 relatively straightforward process and will only take a few minutes.
Start by updating the packages list and installing the dependencies:
sudo apt update
Next, import the Webmin GPG key using the following wget command:
wget -q http://www.webmin.com/jcameron-key.asc -O- | sudo apt-key add -
Enable the Webmin repository:
sudo add-apt-repository "deb [arch=amd64] http://download.webmin.com/download/repository sarge contrib"
Install the Webmin package by typing:
sudo apt update && sudo apt install webmin
Once the installation is complete, the following output will be displayed:
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! At this point, you have successfully installed Webmin on your Debian 9 server.
Adjust the Firewall
By default, Webmin listens for connections on port
10000 on all network interfaces.
If your server runs a UFW firewall, you’ll need to open the Webmin port.
To allow traffic on port
10000 run the following command:
sudo ufw allow 10000/tcp
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
The browser will complain about the certificate being not valid because 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 9 server as per your requirement.
To upgrade your Webmin installation when new releases are published, you can use the
apt package manager normal upgrade procedure:
sudo apt update
