How To Install Caddy on AlmaLinux 9

In this article, we will show you how to install Caddy on your AlmaLinux Systems.

Caddy is a powerful, enterprise-ready, open source web server with automatic HTTPS written in Go. It is an ultimate server. It simplifies your infrastructure. Also, it takes care of TLS certificate renewals, OCSP stapling, static file serving, reverse proxying, Kubernetes ingress, and more.
