nginx模式不支持pathinfo模式，类似info.php/hello形式的url会被提示找不到页面。下面的通过正则找出实际文件路径和pathinfo部分的方法，让nginx支持pathinfo。

location ~ \.php$ {root html;fastcgi_pass 127.0.0.1:9000;fastcgi_index index.php; ##通过设置模拟出pathinfoset $path_info “”;set $real_script_name $fastcgi_script_name;if ($fastcgi_script_name ~ “^(.+?\.php)(/.+)$”) { set $real_script_name $1; set $path_info $2;}fastcgi_param SCRIPT_FILENAME $document_root$real_script_name;fastcgi_param SCRIPT_NAME $real_script_name;fastcgi_param PATH_INFO $path_info; include fastcgi_params;}

要点：

1.~ \.php 后面不能有$ 以便能匹配所有 *.php/* 形式的url
2. 通过设置更改 SCRIPT_FILENAME

我在实际使用张将这段代码融合到了fastcgi_params中。下面是我的nginx配置文件示例：
配置虚拟主机部分，支持pathinfo的nginx代码如下：

## 在nginx.conf的server部分：

server {listen 8080;server_name localhost; location ~ \.php {include fastcgi.conf;}}

##要点： \.php 后面没有$，以便匹配所有 *.php/* 形式
##重点代码见 fastcgi.conf 开头部分

fastcgi.conf 代码如下：

fastcgi_pass 127.0.0.1:9000;##fastcgi_index index.php;set $path_info "";set $real_script_name $fastcgi_script_name;if ($fastcgi_script_name ~ "^(.+?\.php)(/.+)$") {set $real_script_name $1;set $path_info $2;}fastcgi_param SCRIPT_FILENAME $document_root$real_script_name;fastcgi_param SCRIPT_NAME $real_script_name;fastcgi_param PATH_INFO $path_info;## 以上是支持pathinfo的重点部分fastcgi_param GATEWAY_INTERFACE CGI/1.1;fastcgi_param SERVER_SOFTWARE nginx;fastcgi_param QUERY_STRING $query_string;fastcgi_param REQUEST_METHOD $request_method;fastcgi_param CONTENT_TYPE $content_type;fastcgi_param CONTENT_LENGTH $content_length;#fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;#fastcgi_param SCRIPT_NAME $fastcgi_script_name;fastcgi_param REQUEST_URI $request_uri;fastcgi_param DOCUMENT_URI $document_uri;fastcgi_param DOCUMENT_ROOT $document_root;fastcgi_param SERVER_PROTOCOL $server_protocol;fastcgi_param REMOTE_ADDR $remote_addr;fastcgi_param REMOTE_PORT $remote_port;fastcgi_param SERVER_ADDR $server_addr;fastcgi_param SERVER_PORT $server_port;fastcgi_param SERVER_NAME $server_name;# PHP only, required if PHP was built with --enable-force-cgi-redirect#fastcgi_param REDIRECT_STATUS 200;

自己的配置：

server{listen 80;server_name ;index index.html index.htm index.php;root /data0/htdocs/openid; location ~ \.php($|/) {set $script $uri;set $path_info "";if ($uri ~ "^(.+\.php)(/.+)") {set $script $1;set $path_info $2;}fastcgi_pass 127.0.0.1:9000;include fastcgi_params;fastcgi_param PATH_INFO $path_info;fastcgi_param SCRIPT_FILENAME $document_root$script;fastcgi_param SCRIPT_NAME $script;}
