Nginx Server Block (Virtual Host) Installation – Rocky Linux 9

What will you learn in this guide?​

This guide explains how to run multiple domains on a single server using Nginx on Rocky Linux 9.
You learn the server block logic and create a separate root directory and configuration for each site.

1. Creating Document Root Directories​

  • A separate directory structure is required for each domain.
    This structure isolates the sites from each other.
sudo mkdir -p /usr/share/nginx/ornek-site.com/html
sudo mkdir -p /usr/share/nginx/test-site.com/html
  • These commands create the necessary folders for each site.
  1. Set directory ownership and permissions:

sudo chown -R $USER:nginx /usr/share/nginx/ornek-site.com/html
sudo chown -R $USER:nginx /usr/share/nginx/test-site.com/html
sudo chmod -R 775 /usr/share/nginx
  • This process allows Nginx to access the files.

2. Creating Sample HTML Pages​

  1. Create a simple test page for each site.

nano /usr/share/nginx/ornek-site.com/html/index.html

<html>
  <head>
    <title>ornek-site.com</title>
  </head>
  <body>
    <h1>ornek-site.com çalışıyor</h1>
  </body>
</html>
  1. Copy and edit the file for the second site:

cp /usr/share/nginx/ornek-site.com/html/index.html /usr/share/nginx/test-site.com/html/
nano /usr/share/nginx/test-site.com/html/index.html
  • This page indicates that you have accessed the correct site.

3. Creating Nginx Server Block Files​

  1. Nginx loads additional configurations from the conf.d directory in Rocky Linux 9.

Initial Domain Configuration​


sudo nano /etc/nginx/conf.d/ornek-site.com.conf

server {
    listen 80;
    listen [::]:80;

    root /usr/share/nginx/ornek-site.com/html;
    index index.html;

    server_name ornek-site.com www.ornek-site.com;

    location / {
        try_files $uri $uri/ =404;
    }
}
  • This configuration satisfies the first domain name.

Second Domain Configuration​


sudo cp /etc/nginx/conf.d/ornek-site.com.conf /etc/nginx/conf.d/test-site.com.conf
sudo nano /etc/nginx/conf.d/test-site.com.conf

server {
    listen 80;
    listen [::]:80;

    root /usr/share/nginx/test-site.com/html;
    index index.html;

    server_name test-site.com www.test-site.com;

    location / {
        try_files $uri $uri/ =404;
    }
}
  • This file manages the second site.

4. Testing Configuration and Restarting Nginx​

  1. Check the syntax first:

sudo nginx -t
  • This command checks for configuration errors.
  1. If everything is OK, restart Nginx:

sudo systemctl restart nginx
  • Changes become active at this stage.

5. Local Testing with Hosts File (Optional)​

  1. If your domain names are not DNS-oriented, you can do local testing.

sudo nano /etc/hosts

203.0.113.10 ornek-site.com www.ornek-site.com
203.0.113.10 test-site.com www.test-site.com
  • This process temporarily redirects domains to the server.

6. Final Check​

  1. Visit these addresses from the browser:

Frequently Asked Questions (FAQ)​

1. Should I use default_server? No. The default block is sufficient for unmatched requests.

2. How many sites can I run on the same server? There is no practical limit, as long as the hardware allows it.

3. What should I do if I want to add HTTPS? You must add SSL configuration in each server block.

4. Can I use sites-available instead of conf.d? The default structure in Rocky Linux is the conf.d directory.

Result​

Multiple domain management using Nginx server block on Rocky Linux 9 is now ready. This structure provides a scalable and streamlined web server architecture. For production environments, you can easily implement this structure on GenixNode servers.
