配置nginx,支持php的pathinfo路径模式

nginx模式默认是不支持pathinfo模式的，类似index.php/index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。
本文基于安装lnmp一键安装包，添加虚拟主机情况下进行修改
如你要添加一个网站www.linuxeye.com支持pathinfo，配置文件nginx.conf不用任何改变（个人习惯），参考lnmp一键安装包
cat vhost/www.linuxeye.com.conf

server {
listen  ;
server_name     www.linuxeye.com;
access_log  logs/www.linuxeye.com.log combined;
root /home/wwwroot/www.linuxeye.com;
error_page    /.html;
index index.html index.htm index.php ;
location / {
        index  index.php;
        if (!-e $request_filename) {
        rewrite  ^/(.*)$  /index.php/$  last;
        break;
        }
}
location ~ \.php {
fastcgi_pass 127.0.0.1:;
fastcgi_index index.php;
include fcgi_pathinfo.conf;
set $real_script_name $fastcgi_script_name;
    if ($fastcgi_script_name ~ "^(.+?\.php)(/.+)$") {
    set $real_script_name $;
    set $path_info $;
        }
fastcgi_param SCRIPT_FILENAME $document_root$real_script_name;
fastcgi_param SCRIPT_NAME $real_script_name;
fastcgi_param PATH_INFO $path_info;
        }
}

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

cat fcgi_pathinfo.conf

#fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
#fastcgi_param  SCRIPT_NAME        $fastcgi_script_name; #这两行是需要注释掉的,请注意
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  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;
fastcgi_param  HTTPS              $https if_not_empty;

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;

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    ;
