nginx服务器除了更目录可以访问，其他都出现404

配置如下：

listen        80;
  server_name   www.hongtaofei.com;

  location / {
        root    /home/www/shop/public;
        index  index.html index.htm index.php;

         try_files $uri $uri/ /index.php?$query_string;
         if (!-e $request_filename){
             rewrite ^/(.*) /index.php last;
         }
  }

  location ~ \.php$ {
    root    /home/www/shop/public;
    fastcgi_pass 127.0.0.1:9000;
    fastcgi_index index.php;
    include fastcgi.conf;
    include        fastcgi_params;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
  }
}

**注意：这是个人写的配置，一定要加try_files $uri $uri/ /index.php?$query_string 这行**
