LAMP or Linux, Apache, MySQL, and PHP is a typical stack for hosting websites on the internet. They work together as a web server, database, and scripting language for dynamic websites. They are all free, very capable, and also very configurable.
You can install each of these components separately on any Linux system, but Ubuntu made it easy to create a LAMP stack by creating a lamp-server task for apt. task is a meta-package for apt where it installs a group of packages along with the dependencies. A lamp-server task provides Apache, MySQL, and PHP installation for apt on Ubuntu with reasonable defaults and minimal effort.
