Virtualmin is a web hosting control panel for Linux based Operating system like cPanel or Plesk. Virtualmin software Available in Open Source community-supported edition, and a more feature-filled Professional web Licence version.

Virtualmin GPL

This is the absolutely free version, licensed under the GPL. It is under active development, but does not contain all of the features of the Pro version.

Virtualmin Pro

This is the commercial version that you have to pay for. It includes numerous features not in the GPL version.

More details about can be found from below link

Virtualmin is build on top of Webmin, where Webmin is a Linux/UNIX systems management graphical user interface. So in additional to virtual web hosting capabilities like manage websites, mailbox users, databases, and web applications the Virtualmin also have the capability of managing Server settings. Virtualmin is for serious system administrators who expect more than just a flashy user interface over the LAMP stack.

The url used to access Virtualmin and Webmin are identical and features available in the panel depend on the Permission level of user we used to login. We use the provided install script for everything we need to use with Virtualmin, including Webmin. After installation we will configure everything we need to setup before creating a website through virtualmin using graphical interface. After that we will create our first website through virtualmin.

The New Virtualmin software is Faster, Better, Flexible, More Configurable User interface and Mobile friendly than the older versions.

Virtualmin Operating System Supports.

Virtualmin can be installed on CentOS 6,7,8 Systems, Debian 9 and 10 , Ubuntu 16.04 LTS, 18.04 LTS and 20.04 LTS.
