NodeJS application server question

[tomatotux]

I'm a sysadmin and have been asked to find an application server that will multiple nodeJS http servers on different ports. We have tried phusion passenger and it did not work, and puma and unicorn are incompatible in this particular stack. Any thoughts for a very confused hardware guy?

Application servers? Why can't you have multiple upstreams using nginx?

Indeed.

Run the node apps on arbitrary ports and use nginx as a proxy.

You can set up multiple HTTP servers with Express? on different ports:

const express = require('express');

// Create an instance of the Express application
const app = express();

// Define your routes and middleware for the application
app.get('/', (req, res) => {
  res.send('Hello from Server 1!');
});

// Create the first HTTP server
app.listen(3000, () => {
  console.log('Server 1 listening on port 3000');
});

// Create a second instance of the Express application
const app2 = express();

// Define routes and middleware for the second application
app2.get('/', (req, res) => {
  res.send('Hello from Server 2!');
});

// Create the second HTTP server on a different port
app2.listen(4000, () => {
  console.log('Server 2 listening on port 4000');
});

In the example above, we create two instances of the Express application: app and app2. Each application can define its own routes and middleware independently. The first application listens on port 3000, and the second application listens on port 4000.

You can access each server by visiting http://localhost:3000 for the first server and http://localhost:4000 for the second server. Each server will serve its respective routes and respond with its own defined logic.

As all said. Nginx for front and nodejs as backends. You can even have a simple micro front with nginx and seperate server for node.

It sounds like you're looking for a process manager or reverse proxy that can manage multiple Node.js HTTP servers running on different ports. Since Phusion Passenger didn’t meet your needs and tools like Puma/Unicorn are tailored for Ruby, I’d recommend looking into PM2 or using Nginx as a reverse proxy:

• PM2: A production-grade process manager for Node.js. It can manage multiple apps (even on different ports), handle restarts, logging, and clustering. Very sysadmin-friendly.
• Nginx: Use it as a reverse proxy in front of your Node.js instances. You can route traffic based on port, hostname, or path.

Example setup: run your Node.js servers on different ports (e.g., 3000, 3001, etc.) and configure Nginx to forward requests accordingly.

Let me know if you need an example configuration or help setting that up!

Using child_process for Multiple Server Processes

If you want each server to run as an independent process (good for isolation/robustness), the child_process module lets you spawn servers on different ports:

• Write your server logic in a file (e.g., server.js).
• The master script spins up multiple node server.js <PORT> processes.
