Welcome to our guide on Apache Server in Linux. Apache HTTP Server, commonly known as Apache, is a free and open-source web server software that is cross-platform and can operate on Windows, UNIX-like systems, and Linux. Developed and maintained by the Apache Software Foundation, Apache is widely popular and is the most used web server software globally. In this article, we will be discussing the basics of Apache Server, its features, advantages, disadvantages, and much more.
What is Apache Server? π€
Apache is a web server software that is designed to serve HTTP documents over the World Wide Web. It is an open-source software that is free to use, distribute, and modify. Apache is built to cater to the needs of modern web servers and is capable of handling complex web applications with ease. Apache Server is written in C language, and it is highly configurable, extensible, and provides a robust and scalable platform to host web applications.
The History of Apache Server
The Apache HTTP Server was first released in 1995 by a group of developers under the name of Apache Group. The name was derived from the phrase, “A patchy webserver,” which described the process of applying patches to the existing NCSA HTTPd server. The Apache Group was later renamed the Apache Software Foundation in 1999, and since then, Apache has been continuously developed and maintained by the foundation.
How Does Apache Server Work? π οΈ
Apache Server works by responding to the requests sent by the clients browsing the web. When a user enters a URL into the browser, a request is sent to the server hosting the website. The Apache Server receives the request and sends back the requested file or page to the client’s browser. Apache Server uses the standard HTTP protocol to communicate with the clients browsing the web. Apache can be configured to support different programming languages and technologies, such as PHP, Perl, Python, and Ruby.
