Step 6: Set Up Reverse Proxy with Nginx

Nginx is a popular web server that can be used as a reverse proxy for your Node.js application. You can install Nginx by running the following command:

sudo apt-get install nginx

Edit the default Nginx configuration file by running the following command:

sudo nano /etc/nginx/sites-available/default

Replace the contents of the file with the following configuration:

server { listen 80; server_name example.com; location / { proxy_pass http://localhost:3000; 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 close the file. Then, restart Nginx by running the following command:

sudo systemctl restart nginx

Step 7: Verify Your Node.js Application Is Running

You can verify that your Node.js application is running by visiting your server's IP address or domain name in a web browser.

Congratulations! You have successfully set up your Node.js application for production on Ubuntu 16.04.
