⚙️ Step-by-Step: Installing Virtualmin on Your Server
🛑 Important: Only install Virtualmin on a fresh OS. Avoid using a server with pre-installed web stacks like Apache, NGINX, MySQL, or PHP.
🔹 1. Connect to Your Server via SSH
ssh root@your-server-ip
🔹 2. Download the Virtualmin Installer
wget https://software.virtualmin.com/gpl/scripts/install.sh
chmod +x install.sh
🔹 3. Start the Installation
./install.sh
This will launch an interactive installer that will:
- Install Apache/Nginx, PHP, MySQL/MariaDB, Postfix, Dovecot, BIND, Webmin, and Virtualmin
- Set up the initial configuration automatically
🧠 Want unattended install? Use:
./install.sh --minimal
🔹 4. Access Virtualmin Web Interface
Once the install is complete, you’ll get a login URL:
arduinoCopyEdithttps://your-server-ip:10000
⚠️ Accept the browser’s SSL warning — a self-signed certificate is used by default.
Login using:
- Username:
root - Password: your server’s root password
🧰 What’s Next After Login?
After login, Virtualmin will run a Post-Installation Wizard:
- Choose MySQL or MariaDB
- Select default PHP version
- Enable quotas, DNS, and email
Then, you can:
- Add your first Virtual Server (domain)
- Install WordPress or any PHP app
- Create databases, FTP accounts, and email users
🔐 Optional: Secure Your Panel
Open firewall port 10000 (if using firewalld):
firewall-cmd --permanent --add-port=10000/tcp
firewall-cmd --reload
Install a valid SSL certificate via Let’s Encrypt under:
Virtualmin > Server Configuration > SSL Certificate
