How to Set Up Nginx as a Reverse Proxy Server for PM2 on Fedora 39

To set up Nginx as a reverse proxy server for PM2 on Fedora 39, follow these steps:

Step 1 : Ensure that Nginx is installed on your Fedora 39 system. You can install it using the following command:

sudo dnf install nginx

Step 2 : Create a new configuration file for your app. Replace "example.com" with your actual domain name.

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

Add the following configuration, modifying the values as needed:

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;
    }
}

Save and exit the text editor.

Step 3 : Check the Nginx configuration for syntax errors:

sudo nginx -t

Step 4 : Restart Nginx to apply the new configuration:

sudo systemctl restart nginx

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

setsebool -P httpd_can_network_connect true

Step 6 : Visit the Domain to Verify

Open your web browser and navigate to your domain (e.g., http://example.com). Ensure that the application served by PM2 is accessible through Nginx.

Congratulations! You have successfully set up Nginx as a reverse proxy server for PM2 on Fedora 39.
