我收到错误消息：

FastCGI在stderr中发送：“无法打开主脚本：/home/mesi/web/wordpress/index.php（没有这样的文件或目录）”，同时从上游读取响应头，客户端：xxx。xxx。xxx。xxx，服务器：www.domain。com，请求：“GET/HTTP/1.1”，上游：fastcgi://unix:/var/run/php5-fpm。sock:，主机：“www.domain。com

设置用户权限：

#adduser www-data messi
#chown -R www-data:www-data /home/messi/web
#chmod -R 664 /home/messi/web/wordpress

我如何解决这个问题？谢谢
