How To Setup Nginx Reverse Proxy

Setup Nginx Reverse Proxy

In this tutorial, we will show you how to set up a reverse proxy. For those of you who didn’t know, A Nginx HTTPS reverse proxy is an intermediary proxy service that takes a client request, passes it on to one or more servers, and subsequently delivers the server’s response back to the client. If you have multiple servers, a reverse proxy can help balance loads between servers and improve performance. As a reverse proxy provides a single point of contact for clients, it can centralize logging and report across multiple servers.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step by step to set up a reverse proxy.
