Prerequisites for running the PmWiki wiki engine:

1. PHP 4.3 or later
   • PHP 5.3 or later is recommended
   • for PHP 5.5 to 7.4 compatibility use the current version of PmWiki
2. Some sort of webserver that can run PHP scripts.

PmWiki 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 or later is recommended
• lighttpd (1.4.19 php-fastcgi ssl) on Linux
• nginx (0.8.47) on Windows
• Microsoft Internet Information Server, on Windows
• Linux + LiteSpeedWeb Server Standard Edition
• appWeb (a small, php-enabled webserver) executing on a Linksys NSLU2 Network Storage Link device
• Linux + Hiawatha

PmWiki 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 PmWiki in places where another webserver isn't available. PmWiki can also be run from a USB drive.
