LAMP is a software bundle. The acronym LAMP refers to first letters of the components of the solution stack composed entirely of free and open-source software, suitable for building high-availability heavy-duty dynamic web sites, and capable of serving tens of thousands of requests simultaneously.
Linux is a Unix-like and POSIX-compliant computer operating system assembled under the model of free and open source software development and distribution. The main forms of distribution are Linux distributions, usually providing complete LAMP setups out of the box through their package management systems. Of the most widespread Linux distributions, as of 1 October 2013, Debian and Ubuntu are together at the web server’s market share of 58.5%, while RHEL, Fedora and CentOS are at 37.3%.
Many options are available for customizing and securing Linux installations, for example by using SELinux, or by employing chroot environments.
MySQL is a multithreaded, multi-user, SQL database management system (DBMS) now owned by Oracle Corporation. Alternatives at this level of the stack do also exist, primarily the MySQLfork MariaDB. Other RDBM Systems such as PostgreSQL (LAPP) are also viable. MySQL has been owned by Oracle Corporation since January 27, 2010 through the purchase of Sun Microsystems. Sun had originally acquired MySQL on February 26, 2008.
