PM2 VS Phusion Passenger

GitHub: PM2 Repository

You can run the command pm2 status to check if both servers are online and running, as shown below. To learn about all of the other PM2 commands, read the documentation on PM2 Process Management Quick Start:

For teams using NGINX+PM2, moving to NGINX + HashiStack is a more robust and flexible solution—a great fit for startups looking for scalability without the complexity of Kubernetes.

What we wanted was something like a supercharged pm2, but multi-node with good support for both docker and binaries.

Start by registering the app using the official guide.

Run the application using PM2 (ref: Process manager for Node.js)

We split the staging server into two instances using Ubuntu 22.04 as the base image. The first instance is for a web server with nginx,  passenger and MySQL. The second instance is for the support server and this is where we install redis, memcache, mongodb and resque.

Secondly, there is, of course, a bug with Passenger and /var/run/passenger-instreg (I can be found in that thread whining). My preferred fix for this is

While there is a debate on which ones are the best, we will be using Passenger and Nginx, since they are both fast and reliable. You may wish to do your own research and see which one works for you.

In this tutorial we will be deploying a Rails app with Passenger, as the application server, and Nginx, as the web server. Also, the Rails app will use Postgres, so we will be installing that as well.

Here's Puma's implementation, and Here's Passenger's implementation.

PHP is great, but not for all of us. What about running Node.js or Python apps? You might be tempted to use proxy_pass but it won't handle the app startup and crashes for us. Luckily we have a better option: Phusion Passenger.

I have been following all day guides on https://www.phusionpassenger.com/ on how to deploy Rails apps with Apache and Passenger.
