Install and Use Webmin on Ubuntu 22.04

This tutorial intends to teach you to Install and Use Webmin on Ubuntu 22.04.

Webmin is a Linux/Unix system administration tool that can be accessed via a web browser.
Additionally, Webmin can be used to control multiple machines from a single interface or to seamlessly log in to other Webmin hosts on the same network.

Steps To Install and Use Webmin on Ubuntu 22.04

To complete this guide, you must log in to your server as a non-root user with sudo privileges and set up a basic firewall. To do this, you can follow our guide on Initial Server Setup with Ubuntu 22.04.

Install Webmin on Ubuntu 22.04

First, you need to update your local package index with the command below:

sudo apt update 

Then, install the required packages by running the following command:

sudo apt install gnupg2 curl -y

By default, Webmin packages aren’t available in the default Ubuntu repository. So you must add the Webmin repository to your server.

Add Webmin GPG key

To do this, download and add the Webmin GPG key with the following wget command:

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

Add Webmin Repository

Next, use the command below to add the Webmin repository:

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

When you are finished, run the system update:

sudo apt update

At this point, you can use the following command to install Webmin:

sudo apt install webmin -y

When your installation is completed, let’s see how to start and enable your service.

Manage Webmin Service on Ubuntu 22.04

You can start your Webmin service on your server by running the command below:

sudo systemctl start webmin

To enable your service to start on boot, run the command below:

sudo systemctl enable webmin

Verify your Webmin service is active and running on Ubuntu 22.04:

sudo systemctl status webmin

In your output you will see:

Output
● webmin.service - Webmin server daemon
     Loaded: loaded (/lib/systemd/system/webmin.service; enabled; vendor preset>
     Active: active (running) since Sun 2023-02-19 10:03:08 UTC; 22s ago
   Main PID: 3233 (miniserv.pl)
      Tasks: 1 (limit: 4575)
     Memory: 116.5M
        CPU: 9.945s
     CGroup: /system.slice/webmin.service
             └─3233 /usr/bin/perl /usr/share/webmin/miniserv.pl /etc/webmin/min>

Configure Firewall for Webmin

At this point, we assumed that you have enabled UFW firewall from the requirements.

By default, Webmin listens on port 100000. You can check it using the following command:

ss -antpl | grep 10000

You should see the following output:

Output
LISTEN 0      4096         0.0.0.0:10000      0.0.0.0:*    users:(("miniserv.pl",pid=3233,fd=5))

Now you need to allow Webmin port 10000 through the Ubuntu firewall with the following command:

sudo ufw allow 10000

Reload the firewall to apply the new rules:

sudo ufw reload

Access Webmin Dashboard

At this step, you can access your Webmin dashboard on Ubuntu 22.04 through the web interface by typing your server’s IP address in your web browser followed by 10000:

https://server-ip:10000

You will see your Webmin login screen:

Provide your root username, and password, and click on the Sign in button. You should see the Webmin dashboard:

Now from your Webmin dashboard, you can perform your tasks.

Use Webmin on Ubuntu 22.04

From your dashboard, in the left pane, click on Tools => Command Shell. You can access your Linux terminal and execute your commands.

To upload and download any file to your Ubuntu 22.04 server, Click on Tools => Upload and Download from your Webmin dashboard.

Click on the Networking => Network Configuration. You should see the network configuration wizard.

From here, you can set up a static IP address, default gateway, hostname, and DNS.
