Why Virtualmin for Your Organization Network?

Virtualmin is a powerful web server management tool that helps you securely host multiple websites and services. With a user-friendly interface, you can manage user accounts, databases, and SSL certificates – perfect for organizations wanting to control their online presence.

Prerequisites

A VPS or dedicated server with Linux (e.g., Ubuntu or CentOS)
Root access (SSH)
A domain pointing to your server

If you don't have a server yet, check out our VPS Servers – they provide the ideal foundation for Virtualmin.

Step 1: Install Virtualmin

Connect via SSH to your server and run the installation script:

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

Follow the instructions. After installation, access the web interface at https://your-ip:10000.

Step 2: Initial Configuration

Log in with your root user. Go to Virtualmin → System Settings → Server Templates and adjust the default template to your needs. Enable SSL/TLS for all services.

Step 3: Add Users and Domains

Create a separate user for each department or project. Click on Create Virtual Server and enter the domain. Virtualmin automatically sets up email, databases, and SSL.

Step 4: Increase Network Security

Configure the firewall via Virtualmin → Webmin → Firewall. Allow only necessary ports (80, 443, 22). Enable Fail2Ban under Webmin → Servers → Fail2Ban to block brute-force attacks.

Automatically Manage SSL Certificates

Go to Virtualmin → Services → SSL Certificate and enable automatic renewal with Let's Encrypt. This ensures all your sites are encrypted by default.

Step 5: Backup Strategy

Set up regular backups under Virtualmin → Backup and Restore → Scheduled Backups. Store the backups on external storage, e.g., S3 or rsync server.
