Installation of Nginx on Ubuntu

Introduction 

 Nginx is one of the most popular web servers in the world and is responsible for hosting some of the largest and highest-traffic sites on the internet. It is more resource-friendly than Apache in most cases and can be used as a web server or reverse proxy. In this guide, we’ll explain how to install Nginx on your Ubuntu 18.04 server and use that as a reverse proxy for microservices created in flask and other applications. 

 Prerequisites 

 Before you begin this guide, you should have the following: An Ubuntu 18.04 server and a regular, non-root user with sudo privileges. Additionally, you will need to enable a basic firewall to block non-essential ports. You can learn how to configure a regular user account and set up a firewall by following our initial server setup guide for Ubuntu 18.04.
