Install Caddy on Ubuntu 20.04

In this tutorial, we will show you how to install Caddy on Ubuntu 20.04 LTS. For those of you who didn’t know, The Caddy web server is an open-source web server written in Go. It is designed around simplicity and security that comes with a number of features that are useful for hosting websites. Caddy is both a flexible, efficient static file server and a powerful, scalable reverse proxy.

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 the step-by-step installation of the Caddy web server on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.

Prerequisites

  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • A non-root sudo useror access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.
