Prerequisites for running the PmWiki wiki engine:

1. [Link requires approval](approve) 5.3 or later
   • for PHP 5.5 to 8.1 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)
  • [Link requires approval](approve) or later is recommended
• [Link requires approval](approve) (1.4.19 php-fastcgi ssl) on Linux
• [Link requires approval](approve) (0.8.47) on Windows ([Link requires approval](approve))
• Microsoft Internet Information Server, on Windows
• Linux + [Link requires approval](approve) Standard Edition
• appWeb (a small, php-enabled webserver) executing on a Linksys NSLU2 Network Storage Link device
• Linux + [Link requires approval](approve)

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.
