What are the requirements for running Xoops?

Software Requirements

- A web (www) server (Apache, IIS, Roxen, etc) - PHP Version 4.1.0 or higher for XOOPS 2.0.x - PHP version 4.2.0 or higher for XOOPS 2.2.x
- MySQL Database 3.23.XX or 4.X.XX Note: XOOPS 2.0.10 and higher is compatible with - but does not require - PHP5. PHP 4.4 and PHP 5.1 will display quite a number of PHP notices regarding "only variables should be returned by reference" when PHP debug is turned on. This will be fixed in future XOOPS versions. Note: one user has reported a problem with MySQL 3.23.49a-MAX. You will likely have difficulties with this version. Note: if you have a large number of users (several hundred or more), people have reported problems with PHP 4.1.2 which go away when upgrading to a later version of PHP. Note: XOOPS works very well with PHP 4.3.4 and mySQL 4.0.15 Standards

Access/Permission Requirements

If the above software (PHP, MySql, web server) already exist on your server, you do not need special privileges to get Xoops running. (You may need e.g. root privilege if any of the above software needs to be installed/upgraded.) For example, an account on a shared host typically has the required privileges. If your shared host does not provide an automatic method for setting up Xoops, you may need to obtain the latest version of Xoops and upload it to your account. (See Installation Guide for installation instructions.) You also need a MySql account, which is typically provided with shared hosting. Depending on the setup, you may have one single database that must be shared by all your programs (make sure to use the database 'prefix'), or the account may have privileges to create a new database just for Xoops. (See Setting Up MySql and Installaion Guide for details.)

Hardware Requirements

There are no specific hardware requirements provided you can find the above software and provided your server has a network connection. People have Xoops successfully running on the following platforms  Windows 98, 98SE, 98ME Windows 2003 Standard Windows 2003 Enterprise Windows 2000 Windows XP Windows NT Linux Mac OS X
