无法访问var / www ubuntu中的复制文件

I'm on Ubuntu 14.10 .
I copied a subdirectory which has project files (php, html, css) from xampp/htdocs on my Windows PC into /var/www/ of my ubuntu.
However, when I access those files from browser (I can not see the directory listing), I get 402 Object not found. Hence that, I installed Apache2,mysql 5.5 and phpmyadmin and also conducted update apt-get update for the system and I granted chmod-R 777 access to /var/www.
Any idea what might be the problem?

You must put the files on /var/www/html Then try sudo chmod -R 755 /var/www/html
