How to Host Multiple Websites on a Single VPS with Nginx
If you are using a VPS, one of the smartest ways to save money and maximize resources is to host multiple websites on the same server.
Instead of buying separate hosting for each website, you can configure your VPS to serve multiple domains using Nginx.
In this guide, you’ll learn how to host multiple websites on a single VPS with Nginx, step by step.
How It Works
Nginx uses server blocks (similar to virtual hosts) to serve different websites based on domain names.
Example:
- example1.com → Site 1
- example2.com → Site 2
Requirements
- VPS with Ubuntu
- Nginx installed
- Multiple domain names
- Basic Linux knowledge
Step 1: Install Nginx
sudo apt update
sudo apt install nginx -y
Start service:
sudo systemctl start nginx
Step 2: Create Directory Structure
mkdir -p /var/www/site1
mkdir -p /var/www/site2
Step 3: Add Sample Content
echo "Site 1" > /var/www/site1/index.html
echo "Site 2" > /var/www/site2/index.html
Step 4: Set Permissions
chown -R www-data:www-data /var/www
Step 5: Create Server Block for Site 1
sudo nano /etc/nginx/sites-available/site1
Paste:
server {
listen 80;
server_name example1.com;
root /var/www/site1;
index index.html;
}
Step 6: Create Server Block for Site 2
server {
listen 80;
server_name example2.com;
root /var/www/site2;
index index.html;
}
Step 7: Enable Sites
ln -s /etc/nginx/sites-available/site1 /etc/nginx/sites-enabled/
ln -s /etc/nginx/sites-available/site2 /etc/nginx/sites-enabled/
Step 8: Test Configuration
nginx -t
Restart:
systemctl restart nginx
Step 9: Point Domains to VPS
Update DNS:
- A record → VPS IP
Step 10: Add SSL (HTTPS)
Install Certbot:
sudo apt install certbot python3-certbot-nginx -y
Run:
sudo certbot --nginx -d example1.com -d example2.com
Step 11: Verify Setup

Reverse Proxy Apps
Proxy Node.js apps via Nginx.
Performance Optimization
- Enable gzip
- Use caching
- Limit connections
Common Issues
Default Site Showing
Remove default config.
Domain Not Working
Check DNS propagation.
Best Practices
- Separate directories
- Use SSL for all sites
- Monitor logs
Real-World Insight
Most VPS users waste money by:
👉 running only 1 site per VPS
FAQs
How many sites can I host?
Depends on VPS resources.
Is Nginx better than Apache?
Yes for performance.
Final Thoughts
Hosting multiple websites on a single VPS with Nginx is one of the most efficient and cost-effective ways to manage web hosting.
