Introduction
A “LAMP” stack is a group of open-source software that is typically installed together to enable a server to host dynamic websites and web apps. This term is an acronym which represents the Linux operating system, with the Apache web server. The site data is typically stored in a MySQL database and dynamic content is processed by PHP.
On most Linux systems, you can install MySQL by downloading the mysql-server package from your system’s default package management repositories. However, on CentOS 7 the mysql-server package will actually install MariaDB, a community-developed fork of the MySQL relational database management system which works as a drop-in replacement for MySQL. Thus, this tutorial will outline how to install a LAMP stack that consists of Linux, Apache, MariaDB, and PHP on a CentOS 7 server.
