Prerequisites for running the PmWiki wiki engine:
- PHP 5.3 or later
- for PHP 5.5 to 8.1 compatibility use the current version of PmWiki
 
 - 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 (configuration example)
 - 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.
