Table of contents
Requirements
Webserver
TikiWiki can run on any webserver (such as Apache) that supports PHP and meets the following recommended requirements:
- 128MB RAM
- 60 megs free storage
Database
TikiWiki requires an active 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
- Postgress
- Oracle
- Sybase
- MSSQL
PHP
TikiWiki requires PHP 4.1+, version 4.2+ is recommended For PHP 5.0, you must use Tiki 1.9.1 (or higher) with the MySQLi extension.
We recommend using the following configuration in your php.ini file:
PHP.INI setting | Description |
| memory_limit = 16MB | Specify the maximum memory for PHP scripts. We recommend 16MB as a mimimum. For best performance, use 32MB. |
| file_uploads = On | Required to allow uplaods (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.
