How to set up a development server

Introduction

We need at least two servers when managing a product: a development server and a production server.

A good way to get started with a development server is to use a LEMP droplet on DigitalOcean.

We can add new domains using:

certbot --nginx -d example.com -d www.example.com

Then we can set up virtual hosts as explained here.

We can repeat the process to add more domains. The new domains are automatically set up at etc/nginx/sites-available and etc/nginx/sites-enabled.
