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.
Tiki will run in most shared host environments, and many hosts offer Tiki installation via a control panel application (such as Fantastico).
You should verify that your shared host environment meets the minimum requirements:
See Tiki Friendly Hosts for a list of working shared host environments.
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:
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 requires MySQL
in Zend libraries used within Tiki, with PDO (or ADOdb if PDO not available, as within Tiki4).
Libraries | |
libxml must be enabled | http://us2.php.net/manual/en/ref.xml.php |
mbstring is a plus if you work with a language that needs it | http://us2.php.net/manual/en/ref.mbstring.php |
mbstring is required by zend_search_lucene, thus needed for searching in the admin panel, and for managing preferences in perspectives | |
ctype must be enabled for tw >=1.10 |
We recommend using the following configuration in your php.ini file:
PHP.INI setting | Description |
memory_limit = 32M | Specify the maximum memory for PHP scripts. |
file_uploads = On | Required to allow uploads (files, images, etc.) to your Tiki |
upload_max_filesize = XXM | Specify the maxium upload filesize (in MB). |
allow_url_fopen = On | Allow trackback pings in your Tiki blogs. |
session.save_handler = files session.save_path = /tmp | The path that PHP stores session information. Ensure that the location exists and is writable. In Shared Hosting environments, if you do not have access to /tmp, use temp (no slash) instead. |
max_execution_time = 60%%%max_input_time = 60 | Specify the idle timeout (in seconds). If you experience timeouts (such as when performing Admin functions) you may need to increase these settings. |
magic_quotes_gpc = Off | Turn off PHP's Magic Quotes function. |
default_charset = "utf-8" | Specify the default charcter encoding. |
mbstring.func_overload = 0 | Will not work properly with mbstring.func_overload = 7 |
The location of the php.ini file may vary, depending on your operating sytem. Some common locations include:
Notes:
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. |
