Apache HTTP Server Local Development Guide

Install and configure Apache HTTP Server on localhost, default ports 80/8080, local access at http://localhost.

Apache HTTP Server (commonly referred to as Apache or httpd) is one of the most widely used web servers globally. It is open-source, cross-platform, and often combined with PHP and MySQL to form the LAMP stack, serving as a core component for local PHP development.

It listens on port 80 by default; if occupied, you can change it to 8080 in the configuration.
