Install LAMP Stack on Rocky Linux 9 | Best Setup

In this guide, we want to teach you How To Install LAMP Stack on Rocky Linux 9. LAMP stands for Linux, Apache, MariaDB or MySQL, and PHP.

A LAMP stack is used for backend or server-side development. A backend application is a software that runs in an environment that’s hidden from end users. Backend applications consist of the following:

Data processing software
Database components
Business logic in code
API for communicating with other applications

The webpage that shows up on your browser is called the frontend application. When you interact with the page, such as by clicking on a button, your browser communicates with the backend application to retrieve the required information.
