Open Source LAMP - Linux Apache MySQL PHP
Linux is a generic term referring to Unix-like computer operating systems based on the Linux kernel.
Their development is one of the most prominent examples of free and open source software collaboration;
typically all the underlying source code can be used, freely modified, and redistributed, both commercially and non-commercially,
by anyone under licenses such as the GNU General Public License.
The Apache HTTP Server, commonly referred to as Apache, is web server software notable for playing a key role in the initial growth of the World Wide Web.
In 2009 it became the first web server software to surpass the 100 million web site milestone.
Apache was the first viable alternative to the Netscape Communications Corporation web server (currently known as Sun Java System Web Server),
and has since evolved to rival other Unix-based web servers in terms of functionality and performance.
The majority of web servers using Apache run a Linux operating system.
Apache is developed and maintained by an open community of developers under the auspices of the Apache Software Foundation.
The application is available for a wide variety of operating systems, including Unix, GNU, FreeBSD, Linux, Solaris, Novell NetWare, Mac OS X, Microsoft Windows, OS/2, TPF, and eComStation.
Released under the Apache License, Apache is characterized as open source software.
MySQL is a relational database management system (RDBMS) that runs as a server providing multi-user access to a number of databases.
MySQL is officially pronounced ("My S-Q-L"), but is often ("Micey Quell"). It is named for original developer Michael Widenius's daughter My.
The MySQL development project has made its source code available under the terms of the GNU General Public License, as well as under a variety of proprietary agreements.
MySQL is owned and sponsored by a single for-profit firm, the Swedish company MySQL AB, now owned by Sun Microsystems, a subsidiary of Oracle Corporation.
Free-software projects that require a full-featured database management system often use MySQL.
Such projects include (for example) WordPress, phpBB and other software built on the LAMP software stack. MySQL is also used in many high-profile, large-scale World Wide Web products including Wikipedia, Google, Drupal and Facebook.
PHP: Hypertext Preprocessor (the name is a recursive acronym) is a widely used, general-purpose scripting language that was originally designed for web development to produce dynamic web pages.
For this purpose, PHP code is embedded into the HTML source document and interpreted by a web server with a PHP processor module, which generates the web page document.
As a general-purpose programming language, PHP code is processed by an interpreter application in command-line mode performing desired operating system operations and producing program output on its standard output channel.
It may also function as a graphical application. PHP is available as a processor for most modern web servers and as standalone interpreter on most operating systems and computing platforms.
