Caddy is a fast, open-source and security-focused web server written in Go. Caddy includes modern features such as support for virtual hosts, minification of static files, and HTTP/2. Caddy is also the first web-server that can obtain and renew SSL/TLS certificates automatically using Let’s Encrypt.

Before you Begin

Install Go

  1. You need the latest version of Go installed on your Linode. Complete the steps in our guide on installing Go.

Install xcaddy

Install the latest version of xcaddy, a command line tool that downloads and builds Caddy and its plugins for you easily.

  1. Download and install xcaddy:

     sudo apt install -y debian-keyring debian-archive-keyring apt-transport-https
 curl -1sLf 'https://dl.cloudsmith.io/public/caddy/xcaddy/gpg.key' | sudo tee /etc/apt/trusted.gpg.d/caddy-xcaddy.asc
 curl -1sLf 'https://dl.cloudsmith.io/public/caddy/xcaddy/debian.deb.txt' | sudo tee /etc/apt/sources.list.d/caddy-xcaddy.list
 sudo apt update
 sudo apt install xcaddy

Build Caddy

  1. Create a folder named caddy and go to the folder to install Caddy: mkdir ~/caddy cd ~/caddy

  • To build the latest version of Caddy without any plugins: xcaddy build

  • To install Caddy with plugins use the --with option. For example:

      xcaddy build \
    --with github.com/caddyserver/nginx-adapter \
    --with github.com/caddyserver/ntlm-transport@v0.1.1```

  1. Move the caddy executable from the caddy folder to /usr/bin to install:

     sudo mv caddy /usr/bin

  2. To verify the installation of caddy type: caddy version An output similar to the following appears:

     v2.4.4 h1:QBsN1jXEsCqRpKPBb8ebVnBNgPxwL50HINWWTuZ7evU=

Caddy is now installed on your Linode. Read our guide on Installing and Configuring Caddy to learn more about Caddy.
