Mambo System Requirements

What You Need to Run The Mambo Open Source Content Management System

The minimum system requirements for running Mambo on your server space are:

Apache
The operating system Apache is installed on can be anything that the Apache platform supports, but it is Linux, Mac OS X, Windows 2000/XP and BSD that has been tested properly with Mambo. Unix/Linux based systems are recommended, for security and performance reasons.

Apache 1.13.19 or later (2.0.55 recommended)
http://www.apache.org

PHP will need to be installed and configured with Apache.
PHP 4.3.x or above (for security, it is advisable to use PHP 4.4.x versions or higher): http://www.php.net
The MySQL, xml, and zlib modules must also be installed into PHP.

PHP also needs to have a writable session save path. This is configured in the php.ini-file with the line session.save_path = /path. PHP needs to have full access to the folder specified here. On a windows system, this path will be something like session.save_path = C:\Program Files\Something, while a unix system has the session.save_path = /home/var/www-system.

For localised Mambo sites, PHP needs to have GETTEXT installed.

Mambo does not support PHP safe_mode.
While many users run Mambo on servers using safe_mode, the successful operation of Mambo in these circumstances depends very much on how your server has been set up.
safe_mode is not a recommended setting in PHP and is being deprecated in PHP6.

MySQL
The final ingredient is the MySQL database server. Mambo has been tested on MySQL 4.x and 5.x versions. At this time, Mambo does not run in Strict Mode on MySQL 5.x.
