XAMPP itself isn't in the repos but MySQL, PHP, Apache and everything else that is included in XAMPP has a package. It can be done as simple as this:

sudo apt-get install lamp-server^

^{Note: The ^ on the end isn't a typo - it's how we denote tasks.}

XAMPP includes some other things you you probably don't need but you can install most of a command like this (I suggest you only install the things you want, for performance):

sudo apt-get install phpmyadmin proftpd-basic openssl php5-ming php5-gd sqlite3 php5-sqlite php5-mcrypt webalizer php-pear

That affords you a fairly standard stack. The major differences between this and XAMPP are:

• These are set up for production use - with fairly secure defaults
• Apache and MySQL are set to run on boot - XAMPP runs when you tell it to.
• You will get security updates for all these packages through Ubuntu's updater
• You might have to fine tune some of the configuration for your needs

Once you're at that point, you can follow the standard documentation. It might be a little old but most of it should hold true.

To install XAMPP you need to log in as root and then everything works fine, sudo-i is not an option in this case, it still shows some functions as deactivated.
