This page lists the minimum requirements for installing Tikiwiki.
Table of contents
Requirements
Webserver
Tikiwiki should run on any webserver (such as Apache) that supports PHP and meets the following minimal requirements:
- 512 MB Ram
- 100 megs free storage
- At least 32 Megs of Memory allocated for PHP.
Note on PHP Memory Limits: most ISP's install PHP with a memory_limit = 8m. While Tikiwiki may install, and initially appear to work fine, when faced with even a slight load, this limit will be easily passed and the system will constantly fail: pages will not load properly, odd errors will occur etc. To check this limit, try yourdomain.com/tiki-phpinfo.php . Run that and search for three values on your ISP’s server:
- 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
Fantastico and Tikiwiki
Do not assume because your ISP has Fantastico or some other install script or advertises Tikiwiki as supported that they have any experience whatsoever in this. Fantasiko will often install an outdated version of tiki that has known security holes.
Using Fantastico for upgrades is not recommended as it will not preserve any theme changes, image galleries, etc. that have been made.
Database
Tikiwiki requires an active relational database connection. The database can be installed in the same physical location of the webserver (localhost). Tikiwiki supports the following databases:
- MySQL 4.0.x (or higher)
- For MySQL 4.1.x, you must use Tiki 1.9.x (full support)
- For MySQL 5.x, you must use Tiki 1.9.3+. See MySQL5 for details.
- Postgres (partial support)
- SQLite (partial support)
- Oracle (partial support)
- Sybase (partial support)
- MSSQL (partial support)
PHP
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 |
| .... list to be completed |
We recommend using the following configuration in your php.ini file:
PHP.INI setting | Description |
| memory_limit = 16M | Specify the maximum memory for PHP scripts. We recommend 16MB as a mimimum. For best performance, use 32MB. |
| 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. |
The location of the php.ini file may vary, depending on your operating sytem. Some common locations include:
- /etc/php.ini
- /etc/php/php.ini
- /etc/php4/php.ini
- /etc/php/apache1-php4/php.ini (Gentoo)
- /etc/php/cli-php4/php.ini (Gentoo)
- /etc/php4/apache2 (Debian)
Notes:
- PHP 4.1.2 has a known session bug and should not be used.
Optional Software or Libraries
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. |
