What is Virtualmin?

Virtualmin is a Webmin module for managing multiple virtual hosts. It supports Apache, Nginx, BIND DNS, Postfix mail, and multiple databases — making it suitable for hosting agencies and developers managing many sites.

Installation

wget https://software.virtualmin.com/gpl/scripts/virtualmin-install.sh
sudo sh virtualmin-install.sh

The installer runs for 10-15 minutes and configures all services automatically. Access Virtualmin at https://your-server-ip:10000.

Creating a Virtual Server

Go to Virtualmin → Create Virtual Server
Enter the domain name and admin password
Select features: web, SSL, DNS, mail, MySQL database
Click Create Server

Each virtual server gets its own Unix user, home directory, and isolated environment.

Managing Multiple Sites

Use the dropdown at the top of the Virtualmin panel to switch between domains. Each domain has independent settings for:

Web configuration (DocumentRoot, PHP version, .htaccess)
Email accounts and forwarders
DNS records
Database access
SSL certificates

Backup Configuration

Set up automated backups under Virtualmin → Backup Virtual Servers. You can schedule daily backups to local storage, remote FTP, or Amazon S3.
