Meidawiki 配置

为coder建立了一个“编程百科”http://codingwiki.info，codingwiki采用mediawiki，这里记录详细的配置：

codingwiki编程百科站点是一个为Coder而建的关于编程（Coding）的wiki站点，我们期望“新人在这里可以学习提高，熟手在这里可以跨越瓶颈，迈向高手之路”。

codingwiki编程百科 的内容来自国外优秀的Coding博客或者 Coding技术站点。它属于非盈利性的，我们在这里创作、改进、收集和整理编程（Coding）相关的中文文档，当然，我们热烈欢迎您也参与我们的翻译，您可以点击帮助了解相关信息。

如果想要与他人交流获得问题解答（多数情况作为最后选项，既然您已经来了这里：P），请参见建议的通讯方法。

1、首先，配置logo

# logo
$wgLogo = "/logo.png";

2、配置时间

## Timezone Settings
$wgLocaltimezone = "Asia/Shanghai";
$oldtz = getenv("TZ");
putenv("TZ=$wgLocaltimezone");
$wgLocalTZoffset = date("Z") / 3600;
putenv("TZ=$oldtz");

3、配置上传

#开启图片上传
$wgEnableUploads= true;

#上传文件类型
$wgFileExtensions = array( 'png', 'gif', 'jpg', 'jpeg','doc','ppt','pdf' );

4、urlrewrite Url重写

#url REWRITE
$wgScriptPath        = "";
$wgArticlePath      = "/$1";
$wgUsePathInfo      = true;
$wgScriptExtension = ".php";

服务器采用nginx，添加下面的配置

location / {
		if (!-e $request_filename) {
			rewrite ^/([^?]*)(?:\?(.*))? /index.php?title=$1&$2 last;
		}
	}

5、添加常用扩展

#SyntaxHighlight
require_once("$IP/extensions/SyntaxHighlight_GeSHi/SyntaxHighlight_GeSHi.php");

#ParserFunctions
require_once( "$IP/extensions/ParserFunctions/ParserFunctions.php" );

6、实现自己的扩展——找出wiki最热条目和最新条目，以及热门分类，通过扩展tag实现

直接贴代码，详细效果见
