更新：20120820 已确定初审录用，稿件名为 《给Nginx的目录浏览功能加把会变的锁》

写在前面——这个模型本身和NGINX的关系不是太大，Nginx就是一个载体，重要的是如何协同工作的问题，这个同时也是本站搭建用户名和密码下载系统的模型。

正文

我这里写的是一个思路，详细的我会投稿到网管员世界，如果能被选上，大家就会比较详细的知道设计模型了。

广告是一个大家都比较头疼的问题，本站建站初始也不想用广告拉住大家，可广告对网站管理者来说却是有很多好处的，最显著的好处就是能提高广大网站管理者的钱包，只有钱包鼓了，网站才能建的更好，更好的为大家服务。

在不影响大家浏览网页的前提下，我们从资源入手，对特定人群做资源服务。（例如下载和文档等）

实现起来并不难，需要一个广告入口页面，这里分布两个广告，GOOGLE和淘宝的。GOOGLE采用的搜索框形式，而大家也知道，近期GOOGLE总是莫名其妙的无法访问，这也是我引入淘宝的一个主要原因，在GOOGLE死了以后大家也可以通过淘宝广告点击获取用户名和密码。

获取的用户名和密码用在资源下载页，这里也不是什么高深的技巧，用到的是Nginx自身的
auth_basic
对这个不知道的朋友可以搜索一下，BAIDU即可，两行语句搞定

下面就是用户名和密码更新问题了
写了一个脚本，半小时执行一次，数据库和服务器上的文件同时更新，这样就OK了。

然后就是写点击广告的页面了，这个需要一些PHP知识和HTML知识，全OK后带用户名和密码的认证页面就搞定了，对我目前系统进行最小化改造可以达到这个效果。

Changes with nginx 1.2.3                                         07 Aug 2012

    *) Feature: the Clang compiler support.

    *) Bugfix: extra listening sockets might be created.
       Thanks to Roman Odaisky.

    *) Bugfix: nginx/Windows might hog CPU if a worker process failed to
       start.
       Thanks to Ricardo Villalobos Guevara.

    *) Bugfix: the "proxy_pass_header", "fastcgi_pass_header",
       "scgi_pass_header", "uwsgi_pass_header", "proxy_hide_header",
       "fastcgi_hide_header", "scgi_hide_header", and "uwsgi_hide_header"
       directives might be inherited incorrectly.

    *) Bugfix: trailing dot in a source value was not ignored if the "map"
       directive was used with the "hostnames" parameter.

    *) Bugfix: incorrect location might be used to process a request if a
       URI was changed via a "rewrite" directive before an internal redirect
       to a named location.

最近测试，用到了这个，给大家个资源，请勿用于商业环境，谢谢！

Changes with nginx 1.1.14                                        30 Jan 2012
) Feature: multiple "limit_req" limits may be used simultaneously.
) Bugfix: in error handling while connecting to a backend.        Thanks to Piotr Sikora.
) Bugfix: in AIO error handling on FreeBSD.
) Bugfix: in the OpenSSL library initialization.
) Bugfix: the "proxy_redirect" directives might not be correctly        inherited.
) Bugfix: memory leak during reconfiguration if the "pcre_jit"        directive was used.

近期，不知道咋回事，垃圾评论铺天盖地，根本没时间审核，找到了一种方法，可以关闭多少天以前的评论，现记录在此供大家学习使用

修改主题模板文件 functons.php ，加入一个新function

function close_comments( $posts ) {
if ( !is_single() ) { return $posts; }
if ( time() - strtotime( $posts[0]->post_date_gmt ) > ( 30 * 24 * 60 * 60 ) ) {
$posts[0]->comment_status = 'closed';
$posts[0]->ping_status    = 'closed';
}
return $posts;

}

add_filter( 'the_posts', 'close_comments' );

以上30的单位是天，可以按需修改。

——-新版本的wordpress已经带超时评论关闭功能了，在设置里的讨论选项里，大家可以发掘一下

这个问号有两层意思

一为匹配前面的子表达式零次或一次。例如，"do(es)?" 可以匹配 "do" 或 "does" 中的"do" 。? 等价于 {0,1}。

二为当该字符紧跟在任何一个其他限制符 (*, +, ?, {n}, {n,}, {n,m})
后面时，匹配模式是非贪婪的。非贪婪模式尽可能少的匹配所搜索的字符串，而默认的贪婪模式则尽可能多的匹配所搜索的字符串。例如，对于字符串 "oooo"，’o+?’ 将匹配单个 "o"，而 ‘o+’ 将匹配所有 ‘o’。

所以 （.*?）中问号的含义应匹配第二种解释，就是非贪婪模式，最小匹配原则
