查看“如何启用扩展”的源代码

;以启用Math扩展为例，主要参考 [http://www.mediawiki.org/wiki/Extension:Math]

;(1)下载Math的扩展到[http://www.mediawiki.org/wiki/Special:ExtensionDistributor/Math] extension目录下
;(2)更改Localsettings.php,增加一行
 require_once "$IP/extensions/Math/Math.php";
;(3)更新wiki程序，在mantiance目录下执行，或者执行http'':''//example.org/w/mw-config/
 $ php update.php
;(4)[[Special:version]]查看Math扩展是否启用
;(5)选择一个math的生成方法，以MathJax为例, 在localsettings.php里增加

mediawiki[[Special:version|版本]](1.19 - 1.22）
 $wgUseMathJax = true; // enabeling MathJax as rendering option
 $wgDefaultUserOptions['math'] = MW_MATH_MATHJAX; // setting MathJax as default rendering option (optional)
 * The default parser for MathJax is 'http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_HTML'
 * If you don't want to or can't use the default and your run your own locally
 * replace the below url with something like:
 * $wgMathJaxUrl = '/mathjax/MathJax.js?config=TeX-AMS-MML_HTMLorMML';

mediawiki[[Special:version|版本]](1.23+)
 $wgUseMathJax = true; // enabeling MathJax as rendering option
 $wgDefaultUserOptions['mathJax'] = true; // setting MathJax as default rendering option (optional)
 $wgMathDisableTexFilter = true; // or compile "texvccheck"

:(6)测试
 <nowiki><math>E=mc^2</math></nowiki>
<math>E=mc^2</math>

*注：很多数学网站现在都用的是MathJox
