Python Flask Tutorial: Deploying Your Application (Option #1) - Deploy to a Linux Server

description
In this Python Flask Tutorial, we will be learning how to deploy our application to a Linux Server from scratch using Linode. If you would like $20 of free credit towards a Linode account, then you can use my link here to sign up: https://linode.com/coreyschafer We will be covering the entire deployment of a Flask application. This includes spinning up a new Linux Server and tightening its security with SSH keys and firewalls. Then we will install Nginx and Gunicorn so that we can get our Flask App running. Let's get started...
