How to Install Virtualmin (CentOS 7)

What Is Virtualmin?

Virtualmin is a Webmin module typically used to manage multiple virtual hosts through a single interface, similar to cPanel. It supports multiple functions such as creating/managing Apache virtual hosts, MySQL database creation/management, generating DNS zones, managing mailboxes, and much more.

How Do I Install Virtualmin On CentOS 7?

This guide implies that you're using the root account on a Hostwinds Cloud, VPS, or Dedicated Server to perform the installation and that you have a basic working knowledge of a Linux shell.

We highly suggest taking a backup of your server before proceeding with this guide.

Although this guide is written strictly for CentOS 7, Virtualmin offers an automated installation script for the following distros:

• CentOS/RHEL/Scientific Linux 7 on x86_64
• CentOS/RHEL/Scientific Linux 5 and 6 on i386 or x86_64
• Debian 6, 7, and 8 on i386 or amd64
• Ubuntu 12.04 LTS, 14.04 LTS, and 16.04 LTS on i386 or amd64 (non-LTS releases are not supported)

The following steps can install Virtualmin in a CentOS 7 (RHEL 7) environment on a fresh OS installation.

Ensure your server is up to date

yum update -y

Download the Virtualmin installer script using wget

wget http://software.virtualmin.com/gpl/scripts/install.sh

Execute the install script

sh install. sh

As per the warning, when the script is executed, ensure that your OS is listed and type "y," then press "Enter" to continue with the installation.

If prompted, you may need to enter in a fully qualified hostname.
