简单对比，2.2.x常见配置格式如下
<VirtualHost *:80>
DocumentRoot "D:/www/Apache24/htdocs"
ServerName localhost
<Directory D:/www/Apache24/htdocs>
DirectoryIndex index.html index.php
Order Deny,Allow
Allow from all
</Directory>
</VirtualHost>
但是这样的配置在2.4.x下是不行的，应该将设置改成如下：
<VirtualHost *:80>
DocumentRoot "D:/www/sphinx/api"
ServerName www.mysphinx.com
<Directory "D:/www/sphinx/api">
Options FollowSymLinks Indexes
Require all granted
AllowOverride All（有这行代码才能隐藏index.php）
</Directory>
</VirtualHost>
其中的一些指令已经无效，如：
Order Deny,Allow
Deny from all
Allow from al
Deny from all 变成：Require all denied
Allow from all 变成：Require all granted
