How to Set Up Nginx as a Reverse Proxy Server for PM2 on Fedora 40

To set up Nginx as a reverse proxy server for PM2 on Fedora 40, follow the steps below.

Step 1 : First, install Nginx using the package manager:

sudo dnf install nginx

Step 2 : Create a new configuration file for your app:

sudo nano /etc/nginx/conf.d/example.com.conf

Inside the file, add the following configuration:

server {
    listen 80;
    server_name 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 : Check the syntax of your Nginx configuration file:

sudo nginx -t

Step 4 : If the configuration syntax is okay, restart Nginx to apply the changes:

sudo systemctl restart nginx

Step 5 : If SELinux is enabled, run the following command to allow Nginx to connect to the network:

sudo setsebool -P httpd_can_network_connect true

Step 6 : Navigate to your domain (e.g., example.com) in your web browser to verify that Nginx is successfully proxying requests to your PM2-managed app.

Congratulations! You have successfully set up Nginx as a reverse proxy server for PM2 on Fedora 40. Nginx will now efficiently route incoming requests to your PM2-managed app, providing a robust and scalable solution for serving your application to users.
