Nginx Reverse Proxy

Overview

This installation will happen on the dsb-node-01.

In this guide, we will set up a reverse proxy for your application using Nginx. This will allow you to manage incoming traffic more effectively and forward requests to your application running on a different port.

Installation Steps

1. Install Nginx

To begin, you need to install Nginx on your server. This can be done using the following command:

sudo apt install nginx

This command will install Nginx along with any required dependencies.

Configuration Steps

After installing Nginx, you need to configure it to act as a reverse proxy for your application.

1. Remove Default Configuration:

   First, unlink the default Nginx configuration file to avoid any conflicts:

   sudo unlink /etc/nginx/sites-enabled/default

2. Create a New Configuration File:

   Next, create a new configuration file specifically for your reverse proxy setup:

   sudo nano /etc/nginx/sites-available/reverse-proxy

   In the file that opens, paste the following configuration:

   server {
       listen 80;
       server_name localhost;
   
       location / {
           client_max_body_size 1000M;
           proxy_pass http://127.0.0.1:8080;
           proxy_set_header Host $host;
           proxy_set_header X-Real-IP $remote_addr;
           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
           proxy_set_header X-Forwarded-Proto $scheme;
       }
   }

   This configuration tells Nginx to listen on port 80 (the default HTTP port) and forward all incoming traffic to your application running on http://127.0.0.1:8080. It also sets various headers that can be useful for your application's logging and security purposes.

3. Enable the New Configuration:

   Activate the new reverse proxy configuration by creating a symbolic link to the sites-enabled directory:

   sudo ln -s /etc/nginx/sites-available/reverse-proxy /etc/nginx/sites-enabled/

4. Restart Nginx:

   Finally, restart Nginx to apply the new configuration:

   sudo systemctl restart nginx

You're Done

You've setup and configured the Nginx reverse proxy!
