To Install LAMP on Ubuntu 20.4.1

Introduction:

LAMP stands for Linux, Apache, MySQL, and PHP. It is a stack of open source software which are used to enable a server to host dynamic websites and web applications. The most important part of LAMP is "AMP" which is Apache, or "Apache HTTP Server". Apache is the software that delivers webpages through the Internet via the HTTP protocol. MySQL is an open source database management system (DBMS) and PHP is a server scripting language.
