求助apache根目录权限问题

Question

httpd.conf中的配置为默认配置
DocumentRoot  "/var/www/html"

在/var/www/html中放置readme.html
在浏览器中输入http://192.1.168.1.233/readme.html可以打开

mkdir /var/www/html/newvbb
cp /var/www/html/readme.html  /var/www/html/newvbb/
chmod 755 -R /var/www/html

然后在浏览器中浏览http://192.1.168.1.233/newvbb/readme.html
报告如下提示：
Forbidden
You don't have permission to access /newvbb/readme.html on this server.

Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.
