最近研究CI框架，发现这个框架的路由功能在Nginx下有问题，报404错误，后来在网上查资料，

发现需要开启PATH_INFO。在nginx7.16以后貌似就支持PATH_INFO了，只需要在配置文件中开启即可。

打开nginx.conf文件，在你的虚拟主机下增加重写规则，代码如下：

复制代码 代码如下:

server {

listen 80;

server_name www.ci.com;

location / {

root d:/www/Codeigniter_2.0.1/;

index index.html index.htm index.php;

rewrite ^/$/index.php last;

rewrite^/(?!index.php|robots.txt|images|js|styles)(.*)$ /index.php/$1last;

}

location ~^(.+.php)(.*)$ {

root D:/www/Codeigniter_2.0.1/;

fastcgi_index index.php;

fastcgi_split_path_info ^(.+.php)(.*)$;

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

fastcgi_param PATH_INFO $fastcgi_path_info;

fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;

fastcgi_pass 127.0.0.1:9002;

include fastcgi_params;

}

}
