Apache:

Forbidden You don't have permission to access / on this server

 

度娘了半天,屁用都没,都是老掉牙的。

最后google之,http://stackoverflow.com/questions/21551840/forbidden-you-dont-have-permission-to-access-on-this-server

 

Found my solution thanks to Error with .htaccess and mod_rewrite
For Apache 2.4 and in all *.conf files (e.g. httpd-vhosts.conf, http.conf, httpd-autoindex.conf ..etc) use

Require all granted

instead of

Order allow,deny
Allow from all

The Order and Allow directives are deprecated in Apache 2.4.
