Prerequisites for running the Pm Wiki wiki engine:

1. PHP(approve sites) 5.3 or later
   • for PHP 5.5 to 8.1 compatibility use the current version of Pm Wiki
2. Some sort of webserver that can run PHP scripts.

Pm Wiki has been reported to work with the following OS/webserver combinations:

• Apache 1.3 or 2.0, on roughly anything (Unix, Linux, Windows, and Mac OS X)
  • Apache 2.4(approve sites) or later is recommended
• lighttpd(approve sites) (1.4.19 php-fastcgi ssl) on Linux
• nginx(approve sites) (0.8.47) on Windows
• Microsoft Internet Information Server, on Windows
• Linux + LiteSpeedWeb Server(approve sites) Standard Edition
• appWeb (a small, php-enabled webserver) executing on a Linksys NSLU 2? Network Storage Link device
• Linux + Hiawatha(approve sites)

Pm Wiki has been reported not to work on:

• Mac OS before Mac OS X because there's no PHP available
• Specific Release Candidate builds of PHP 5.3 for Windows may not work correctly with passwords

The Standalone recipe provides a special, bare-bones webserver application that can be used to run Pm Wiki in places where another webserver isn't available. Pm Wiki can also be run from a USB drive.
