How to Install Caddy_2.7.3_linux_amd64.tar.gz: Complete Guide

Let’s talk about caddy_2.7.3_linux_amd64.tar.gz and why it might be exactly what you need for your server setup.

My Journey from Nginx to Caddy

I spent years wrestling with complex web server configs.

Then I found Caddy.

Let me share what changed everything for me.

Why Caddy Stands Out

• Automatic HTTPS certificates
• Simple, readable config files
• Built-in security features
• Fantastic Linux support
• Less server maintenance
• Smaller attack surface
• Better performance metrics
• Easier debugging process
• Modern architecture design

Getting Started with Caddy

First step – download caddy_2.7.3_linux_amd64.tar.gz:

bashCopywget https://github.com/caddyserver/caddy/releases/download/v2.7.3/caddy_2.7.3_linux_amd64.tar.gz

Extract the package:

bashCopytar xzf caddy_2.7.3_linux_amd64.tar.gz

Set it up properly:

bashCopysudo mv caddy /usr/local/bin/
sudo chown root:root /usr/local/bin/caddy
sudo chmod 755 /usr/local/bin/caddy

Basic Configuration Steps

Create your first Caddyfile:

bashCopysudo mkdir /etc/caddy
sudo touch /etc/caddy/Caddyfile

Add this basic config:

Copyexample.com {
    root * /var/www/example.com
    file_server
    encode gzip
}
