What you need

You only need two things to make this happen. The first is a running instance of Ubuntu Server 18.04. The second is a user with sudo privileges. That’s it. Let’s work.

Update/upgrade

The first thing you must do is make sure that your server is updated and upgraded. Do note, should your kernel be upgraded, you need to reboot the server. Because of this, make sure to run the update/upgrade at a time when a reboot is possible (unless you have live patching installed, at which point you can run the task any time). To update and upgrade, log into the server to host Ansible and issue the following commands:

sudo apt-get update
sudo apt-get upgrade -y

Once that process completes, reboot the server (if necessary). You’re now ready to install.

Install LAMP

As Webmin is a web-based tool, it depends upon a web server. For this we’ll install a full LAMP (Linux Apache MySQL PHP) stack. Log into your server and issue the command:

sudo apt-get install lamp-server^ -y

Once that completes, secure the MySQL installation with the command:

sudo mysql_secure_installation

You will be asked if you want to add the VALIDATE PASSWORD PLUGIN. If you include this, you will also have to configure the minimal security requirements for MySQL passwords. Once beyond that, you can then set a password for the MySQL admin user and then:

  • Remove anonymous users.
  • Disallow root login remotely.
  • Remove test database and access to it.
  • Reload privilege table.

Answer yes to all of the above.

Your LAMP server is ready.

Installing Webmin

Now it’s time to install Webmin. Create a new repository list file with the command:

sudo nano /etc/apt/sources.list.d/webmin.list

Paste the following into that new file:

deb http://download.webmin.com/download/repository sarge contrib

Save and close that file.

Add the necessary GPG key with the commands:

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

Update apt with the command:

sudo apt-get update

Finally, install Webmin with the command:

sudo apt-get install webmin -y

Accessing Webmin

When the installation completes, open a web browser on the same network and point it to https://SERVER_IP:10000 (where SERVER_IP is the IP address of the hosting server). You will be prompted for login credentials (Figure A). Remember, these credentials can be for any user on the Ubuntu server that has sudo privileges.
