This tutorial is going to show you how to install Nginx, MariaDB and PHP7.3 (LEMP stack) on Debian 10 Buster. A software stack is a set of software tools bundled together. LEMP stands for Linux, Nginx, MariaDB/MySQL and PHP, all of which are open source and free to use. It is a very common software stack that powers dynamic websites and web applications. Linux is the operating system; Nginx is the web server; MariaDB/MySQL is the database server and PHP is the server-side scripting language responsible for generating dynamic web pages.
All of the four components are free and open-source. However, since MySQL is now owned by Oracle and there’s a chance that Oracle turns it to a closed-source product, we will choose MariaDB instead of MySQL.
