This page lists the minimum requirements for installing Tikiwiki.
Tikiwiki should run on any webserver (such as Apache) that supports PHP and meets the following minimal requirements:
This limit is not generally user managable so you must rely on the kindness of your ISP to grant you more resources. On a busy shared server that will also mean that all other PHP users on that shared server will also be granted those resources. ^
Tikiwiki requires an active relational database connection. The database can be installed in the same physical location of the webserver (localhost). Tikiwiki works best on MySQL databases:
Tiki requires PHP 4.1+ (if you want to use LDAP authentication you need 4.3.2+), version 4.2+ is recommended. For PHP 5.0, you must use Tiki 1.9.1 (or higher) with the MySQLi extension.
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 |
ctype must be enabled for tw >=1.10 | |
native PHP DOM XML OR Active-Link DOM XML extension installed | for pdf generation tw>=1.10 |
GD PHP Image Extension, version 2.0.28 or newer | for pdf generation tw >=1.10 |
Zlib, Ghostscript, pdflib | highly recommanded for pdf generation tw>=1.10 |

.... list to be completed |
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. |
Notes if safemode is on
You can need
safe_mode_allowed_env_vars = TZ in php.ini
Note: you may also need the php-devel package being installed (and restarted apache) to get past the "blank screen issue" of tiki-install.php. (See forum article about that). Prior to it please check, that you have enabled the proper database in your php.ini.
The location of the php.ini file may vary, depending on your operating sytem. Some common locations include:
Notes:
Some TikiWiki 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+ |
WikiGraph for creating and manipulating graphs. | GraphViz |
Webmail | PHP 4.2+ |
PDF Genration | php-xml |
Manage and display maps as a GeoCMS (Geospastial Content Management System). | Mapserver 4.6+ |
Rewrite Tiki's default URLs | Use the Apache Rewrite Rules to create shorter, or custom, URLs. |
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 Tikiwiki, 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.
