Requirements and Setup
This page lists the minimum requirements for installing Tiki.
If you are using standard shared hosting, you can assume that the requirements are met, as Tiki is designed to run on shared hosting, using the LAMP stack. The instructions below are useful for people that are configuring a server for Tiki.

Requirements
Webserver
Tiki is developed and widely tested with Linux and Apache. However, Tiki should run on any webserver that supports PHP, like Windows/IIS, lighttpd etc. but you should expect to need to tweak things. Please see the Windows compatibility project.
Your webserver should be configured with the following minimal requirements:
- 512 MB RAM
- 100 MB free storage
Database
Tiki requires an active relational database connection. The database can be installed in the same physical location of the webserver (localhost). It can also be a remote database. Tiki is developed and tested mainly on MySQL databases:
- MySQL 5 or higher (require for Tiki3 or higher)
- MySQL 4.1 or higher
Possible but not recommended databases
- PostgreSQL (doesn't work with Tiki3 or Tiki4, but work is ongoing to fix for Tiki5)
- SQLite (doesn't work with Tiki3 or Tiki4, but work is ongoing to fix for Tiki5)
Oracle(abandoned)Sybase(abandoned)MSSQL(abandoned)

PHP
Tiki version 3 (or later) requires PHP 5 with the MySQLi extension.
Tiki version 4 (or later) prefers PHP 5 with the PDO extension. You can revert back to ADOdb if PDO is not available.
- max_execution_time = 300 ; Maximum execution time of each script, in seconds
- max_input_time = 60 ; Maximum amount of time each script may spend parsing request data
- memory_limit = 32M ; Maximum amount of memory a script may consume

[+]Optional Software or Libraries
Some Tiki feautures require the following additional software or libraries:
| Feature | Additional Requirements |
| Image processing, used for thumbnail generation, dynamic chart generation, and to prevent bot/automatic registration. | Use either GD Library 1.5 (or higher) or ImageMagick. ImageMagick is included, by default with PHP 4.3+ |
| Manage and display maps as a GeoCMS (Geospastial Content Management System). | Mapserver 4.6+ |
| Rewrite Tiki's default URLs | Use the Apache Clean URLs to create shorter, or custom, URLs. |
Fantastico (and other ISP panels)
If your web host uses Fantastico or another web hosting control panel, you'll need to verify that their script will install the current version of Tiki, with all the proper security updates.
Using Fantastico for upgrades is not recommended as it will not preserve any theme changes, image galleries, etc. that have been made.
