XAMPP is an independent server platform, which consists mainly of the MySQL database (now MariaDB), the Apache web server and interpreters for scripting languages: PHP and Perl. The name comes from the abbreviation of X (for any of the different operating systems), Apache, MySQL, PHP, Perl. The program is released under the GNU license and acts as a free web server, it easy to use and able to interpret dynamic pages. Currently, XAMPP is available for all the major operating system (GNU/Linux Distributions, Microsoft Windows, Solaris, and MacOS X).
Here I am discussing some tips after installing the XAMPP in Ubuntu (or any version of GNU/Linux).
