Requirements and Setup
This page lists the minimum requirements and recommended settings to install Tiki.
If you are using a standard shared webhost, your webhost most likely meets these requirements and you should be able to install Tiki with no problems. Tiki is designed to run on shared hosting, using the LAMP stack.
These instructions are useful for people that are configuring their own server for Tiki.

Shared Host
Tiki will run in most shared webhost environments. Many hosts offer Tiki installation via a control panel application (such as Fantastico).
You should verify that your webhost meets the minimum requirements:
See Tiki Friendly Hosts for a list of working shared host environments.
Requirements
Webserver
You must have a fully operational webserver in order to install and use Tiki. Tiki should run on any webserver that supports PHP (such as Windows IIS or lighttpd, but is most widely tested and used with Apache. You may need to make minor modifications for non-Apache webservers.
To simply installation on Windows IIs, Tiki is included in the Windows Web App Gallery and can be installed with the Microsoft Web Platform Installer. See Microsoft Web Platform installer for details.
Your webserver should be configured with the following minimum requirements:
- 512 MB RAM
- 100 MB free storage
MySQL
The database can be installed in the same physical location of the webserver (that is, as localhost) or Tiki can access a remote database.
PHP
| Tiki Version | PHP Version | Notes |
|---|---|---|
| Tiki7 | PHP 5.2 | If you can't get PHP 5.2, you can keep on using Tiki6LTS (end of support for Tiki6LTS is when Tiki10 is released) |
| Tiki5 or Tiki6LTS | PHP 5.1 with the PDO extension | If PDO is not available, you can revert to ADOdb. See ReleaseNotes40 for details. (PHP 5.2 is preferred primarily to access features in Zend libraries) and can be necessary for some of the newer features like WebDAV), however, globally, Tiki works with PHP 5.1. |
| ((Tiki4 or later | PHP5 with the PDO extension | If PDO is not available, you can revert to ADOdb. See ReleaseNotes40 for details. |
| Tiki3LTS (or later) | PHP5 with the MySQLi extension | This is a Long Term Support (LTS). End of life is May 2011, where you should upgrade to Tiki6LTS |
To review your PHP Memory Limits, access http://www.yourdomain.com/tiki-phpinfo.php and review the following values:
- max_execution_time = 60 ; 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

| 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 character encoding. |
| mbstring.func_overload = 0 | Tiki will not work properly with mbstring.func_overload = 7. |

Notes:
- If safemode is on you may need safe_mode_allowed_env_vars = TZ in php.ini.
- To run PHP5 on 1and1.com add the following lines to your _htaccess file (Tiki 3):
AddType x-mapp-php5 .php
AddHandler x-mapp-php5 .php
uncomment line 29 and 30 then rename in .htaccess
