Nginx服务器下使用rewrite重写url以实现伪静态的示例

经过网上查阅和测试，发现Nginx的Rewrite规则和Apache的Rewite规则差别不是很大，几乎可以直接使用。比如在Apache中这样写规则

rewrite ^/([0-9]{5}).html$ /viewthread.php?tid=$1 last;

而在Nginx中写成这样写是无法启动的，解决的办法是加上两个双引号：

rewrite "^/([0-9]{5}).html$" /viewthread.php?tid=$1 last;

同时将RewriteRule为Rewrite，基本就实现了Nginx的Rewrite规则到Apache的Rewite规则的转换。

Rewrite的Flags

WordPress的Rewrite
其实在Nginx下配置WordPress的Rewrite还是比较简单的，在location /{..................}里面加入

if (!-f $request_filename){rewrite (.*) /index.php;}

即可实现。

下面是一个完整的vhost的配置文件

server {listen 80;server_name ccvita.com www.ccvita.com;location / {    index index.html index.htm index.php;    root /www/wwwroot/ccvita.com;    if (-f $request_filename/index.html){        rewrite (.*) $1/index.html break;    }    if (-f $request_filename/index.php){        rewrite (.*) $1/index.php;    }    if (!-f $request_filename){        rewrite (.*) /index.php;    }}location ~ /.php$ {    include fastcgi_params;    fastcgi_index index.php;    fastcgi_pass 127.0.0.1:8787;    fastcgi_param SCRIPT_FILENAME /www/wwwroot/ccvita.com$fastcgi_script_name;    }location /ccvita-status {    stub_status on;    access_log off;    }}

Discuz!的Rewrite
下面的Rewrite中百分号前面多了个转移字符“/”，这在Apache中是需要的，而在Nginx中则是不需要的。

rewrite ^/thread-([0-9]+)-([0-9]+)-([0-9]+)/.html$ /viewthread.php?tid=$1&extra=page/%3D$3&page=$2 last;

正确的应该是

rewrite ^/thread-([0-9]+)-([0-9]+)-([0-9]+)/.html$ /viewthread.php?tid=$1&extra=page%3D$3&page=$2 last;

这个错误在基本上目前所有使用Nginx作为服务器，并且开启了Rewrite的网站上存在。包括Discuz!官方，目前已经给cnteacher反馈了。
