How To Install LAMP Stack on Rocky Linux 9

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.
