Real-World Example: NGINX Reverse Proxy Configuration

 

📋 Real-World Example: NGINX Reverse Proxy Configuration

Let’s set up NGINX to act as a reverse proxy for two backend servers running on ports 8080 and 8081.

Step 1: Install NGINX

sudo apt update
sudo apt install nginx

Step 2: Configure NGINX
Edit the default NGINX configuration file:
 
sudo nano /etc/nginx/sites-available/default
 
Add the following configuration: 

server {
    listen 80;

    server_name example.com;

    location / {
        proxy_pass http://backend_servers;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

upstream backend_servers {
    server 127.0.0.1:8080;
    server 127.0.0.1:8081;
}

Step 3: Test and Reload NGINX
 
Test the configuration:
sudo nginx -t
 
Reload NGINX:
 
sudo systemctl reload nginx
 
 
Result:
Clients accessing http://example.com are automatically routed to one of the backend servers,
ensuring load balancing and seamless service delivery.
