Linux Server Setup & MERN App Deployment

These are the steps to setup an Ubuntu server from scratch and deploy a MERN app with the PM2 process manager and Nginx. We are using Linode, but you could just as well use a different cloud provider or your own machine or VM.

Create an account at Linode

Click on Create Linode

Choose your server options (OS, region, etc)
