How to Set Up Nginx as a Reverse Proxy Server for PM2 on Ubuntu 22.04

To establish Nginx as a reverse proxy for PM2 on Ubuntu 22.04, follow these steps:

Step 1 : Install Nginx

If Nginx is not installed, you can install it using:

sudo apt update
sudo apt install nginx

Step 2 : Configure Nginx as a Reverse Proxy

- Create a new Nginx configuration file for your application:

sudo nano /etc/nginx/sites-available/example.devtutorial.io

- Add the following configuration. Make sure to replace example.devtutorial.io with a meaningful name and update the values accordingly:

server {
    listen 80;
    server_name example.devtutorial.io;

    location / {
        proxy_pass http://localhost:3000;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
}

Save the file and create a symbolic link to it in the sites-enabled directory:

sudo ln -s /etc/nginx/sites-available/example.devtutorial.io /etc/nginx/sites-enabled

Step 3 : Test Nginx Configuration

- Before restarting Nginx, it's a good idea to test the configuration:

sudo nginx -t

- If the test is successful, you should see a message indicating that the syntax is okay.

Step 4 : Restart Nginx

- Restart Nginx to apply the changes:

sudo systemctl restart nginx

Step 5 : Access Your Application

You should now be able to access your Node.js application through Nginx. Open a web browser and navigate to http://your_domain_or_ip.

This setup allows Nginx to handle incoming HTTP requests and forward them to your Node.js application managed by PM2.
