Apache2+VirtualEnv IOError:[Errno 13]权限被拒绝

我很难让apache通过virtualenv(和virtualvwrapper)为我的网站服务。我试着跟着演练 here 。值得注意的是,我使用的是Ubuntu Server v13.10,我读到它还没有对Apache v2.2的本机支持,因此在演练中我无法安装apache2.2-common。但是,我认为这不是问题所在,因为Apache错误日志指出存在权限问题。

在我的设置中,虚拟环境位于非root用户的主目录中,而apache服务器以root身份运行(我认为这是正常的)。我已尝试使用跟踪权限 namei 我已经确保 chmod +rw 路径为 root 。有什么想法吗?
