Configure NGINXPermalink
At this point, you could configure Node.js to serve the example app on your Linode’s public IP address, which would expose the app to the internet. Instead, this section configures NGINX to forward all requests from the public IP address to the server already listening on localhost.
Basic Configuration for an NGINX Reverse ProxyPermalink
Create a configuration file for the app in /etc/nginx/conf.d/. Replace example.com in this example with your app’s domain or public IP address:
server {
listen 80;
listen [::]:80;
server_name example.com;
location / {
proxy_pass http://localhost:3000/;
}
}
The proxy_pass directive is what makes this configuration a reverse proxy. It specifies that all requests which match the location block (in this case the root / path) should be forwarded to port 3000 on localhost, where the Node.js app is running.
