LAMP (application stack)

LAMP is an acronym that stands for for "Linux, Apache, MySQL, Perl/PHP/Python." Packaged together, they create an application stack that is both free to use and open source which functions as a general purpose web server.

• Linux is an open source operating system
• Apache HTTP Server is an open source web server middleware
• mySQL is an open source Relational Database Management System (RDBMS, also known simply as a Database)
• PHP, Perl, or Python are server-side programming languages which can be installed on Apache.

Variations

Variations of LAMP packages (referred to as AMP packages) can differ based on the choice of operating system.

• A WAMP stack uses Microsoft Windows.
• The MAMP stack uses Macintosh computers (UNIX-based Mac OS X replaces the operating system layer).
• A SAMP stack uses the Sun Microsystems Solaris operating system.
• XAMPP is a cross-platform version of the bundle that can be downloaded and installed on Microsoft Windows, Mac OS X, Solaris, or Linux.
• OAMP runs on OpenBSD.
• DAMP runs on the Darwin operating system.
• SLAMPP is a Linux distribution that can be booted from an optical disc drive to turn any computer into an instant home web server.
