Commands to install Apache web server on Ubuntu 22.04 or 20.04 LTS
If you want to learn how to run and access a website from a remote location, we need a web server and what is more convenient than getting started with Apache if you are new to the world of IT. accommodation. Here in this tutorial we will learn the command to install and start Apache web server on Ubuntu 22.04 LTS Jammy JellyFish or Ubuntu 20.04 LTS focal fossa.
Apache is the most widely used web server on the Internet. And can be easily configured due to its flexible nature and ability to expand functionality using a large number of modules. It was developed and maintained under the Apache foundation.
Usually the Apache web server is installed with PHP and MySQL / MariaDB. However, Apache itself only provides static HTML pages. However, when combined with PHP (PHP Hypertext Preprocessor) as a scripting language, it can serve dynamic HTML pages generated from database content.
Most popular content management systems (CMS) like WordPress or Joomla therefore also need PHP and MySQL database. And when it comes to installing Apache, all popular Linux distributions like RedHat, CentOS, Ubuntu Debian and others have Apache packages in their respective base repository, so the user can install it with just one command. We can use Apache on Windows but being an open source project and native to Linux systems and their dominance in the server world, hosting services only offer it on Linux to get the full potential of this web server software. .
While these developers are on Windows and working on a web project that requires Apache, typically go with XAMPP or WampServer, like projects, to get the entire LAMP stack up and running easily.
