几乎所有的框架(ThinkPHP，Zend Framework，CI，Yii，laravel等)都会使用URL重写或者pathinfo模式，使URL看起来更美观，比如可以隐藏掉入口文件，并且有利于搜索引擎优化，其实让Nginx支持pathinfo或者重写也不难，首先在php.ini中设置cgi.fix_pathinfo=1

再就是添加配置文件(新版nginx) 内容如下:

#pathinfo 支持开始  以上配置信息根据实际情况配置
  fastcgi_split_path_info ^((?U).+\.php)(/?.+)$;    
  fastcgi_param PATH_INFO $fastcgi_path_info;    
  fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;  
#pathinfo 支持结束

 可能很多童鞋看到以上配置仍然不知道在哪添加这几行配置,下面看一个完成的配置

server
    {
        listen 80 ;
        server_name _;
        index index.html index.htm index.php;
        root  /home/wwwroot/default;
        #匹配php脚本扩展名
        location ~ [^/]\.php(/|$)
        {
            fastcgi_pass  unix:/tmp/php-cgi.sock;
            fastcgi_index index.php;

            #fastcgi相关参数开始  
            fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
            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_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  REQUEST_SCHEME     $scheme;
            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        $server_name;
            fastcgi_param  REDIRECT_STATUS    200;
            fastcgi_param PHP_ADMIN_VALUE "open_basedir=$document_root/:/tmp/:/proc/";
            #fastcgi相关参数结束

            #pathinfo开始
            fastcgi_split_path_info ^(.+?\.php)(/.*)$;
            set $path_info $fastcgi_path_info;
            fastcgi_param PATH_INFO       $path_info;
            try_files $fastcgi_script_name =404;
            #pathinfo结束
        }

        #重写模式开始
        location / {   
                       if (!-e $request_filename){   
                            #rewrite ^(.*)$ /index.php?s=/$1 last;
                            rewrite ^(.*)$ /index.php/$1 last;
                        }
        }
        #重写模式结束
    }

这样Nginx就支持pathinfo了，当然您需要根据您的服务器进行具体的配置，可能会略有变化，切忌机械的照搬照抄。

对于URL重写也比较简单，上面的配置中也已经提到 例如对于THINKPHP可以这样设置

location / {   
                       if (!-e $request_filename){   
                            #rewrite ^(.*)$ /index.php?s=/$1 last;
                            rewrite ^(.*)$ /index.php/$1 last;
                        }
    }
