配置apache时出现You don't have permission to access / on this server错误的解决

今天准备学习php，在安装apache时出现You don't have permission to access / on this server错误。查了一下apache手册找到问题所在处。这里定义了默认对网站根的访问权限。
将：

<Directory />
    Options FollowSymLinks
    AllowOverride None
    Order deny,allow
    Deny from all
</Directory>

改为：

<Directory />
    Options Indexes FollowSymLinks
    AllowOverride None
</Directory>

终于出现It works!
