How to Set Up Nginx as a Reverse Proxy Server for PM2 on Ubuntu 23.10

To set up Nginx as a reverse proxy server for PM2 on Ubuntu 23.10, follow these steps:

Step 1 : Install Nginx

sudo apt update
sudo apt install nginx

Step 2 : Create a New Configuration for the App

Create a new Nginx configuration file for your app. Replace example.com with your actual domain.

sudo nano /etc/nginx/sites-available/example.com

Add the following configuration, adjusting as needed:

server {
    listen 80;
    server_name example.com www.example.com;
     location / {
        proxy_pass http://localhost:your_pm2_app_port;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
}

Step 3 : Enable the Configuration

Create a symbolic link to enable the site configuration:

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

Step 4 : Test the Configuration

Check for syntax errors in the Nginx configuration:

sudo nginx -t

If no errors are reported, proceed to the next step.

Step 5 : Restart Nginx

Restart Nginx to apply the changes:

sudo systemctl restart nginx

Step 6 : Open the Browser

Open your web browser and navigate to your domain (e.g., http://example.com). You should now see your app served through Nginx.

Congratulations! You have successfully set up Nginx as a reverse proxy server for PM2 on Ubuntu 23.10. Your app should now be accessible through Nginx.
