We spin a few Virtual Machines on Microsoft Azure for the internal network, and the image has no Webmin installed by default – not like in this previous post – A Complete Setup Guide for Contabo VPS Ubuntu 20.04 with preinstalled Webmin + LAMP.

Webmin is a web-based tool admins use to manage Ubuntu and Linux servers. The Webmin dashboard allows you to manage, update and configure your system, view system logs and emails, and perform other administrative tasks.

Solution – Step by Step

In the terminal, log in to the remote machine.

Run the following command to update the package list:

sudo apt update

Install the update packages:

sudo apt upgrade

Install dependency packages to manage software repositories by using:

sudo apt install software-properties-common apt-transport-https

Add Webmin GPG key:

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

Add the Webmin repository:

sudo add-apt-repository "deb [arch=amd64] http://download.webmin.com/download/repository sarge contrib"

Install the Webmin:

sudo apt install webmin

Check the status:

sudo systemctl status webmin

Webmin uses the TCP port 10000 by default. Open this port on your firewall:

sudo ufw allow 10000/tcp

Reload your firewall:

sudo ufw reload

Check the status of the firewall to confirm the changes:

sudo ufw status

Set the password for the Webmin root user:

sudo /usr/share/webmin/changepass.pl /etc/webmin root [new_password]

Open the internet browser and enter the following as a web address using the server’s IP:

https://[virtual_machine_IP]:10000/

Webmin generates its SSL certificate not recognised by the browser, which causes a page indicating a potential security risk the first time trying to log in.

Click the Advanced button. Then click the Accept the risk and continue button.

Log in using the default username root and the password set up previously.

The End
