apache 已经加载模块，但是不能解析出开发的rewrite模块功能

例如  这样配置虚拟域名上正确的DocumentRoot与Directory是有顺序的 

<VirtualHost *:80>
    ServerAdmin webmaster@dummy-host.example.com
    DocumentRoot "/usr/local/apache/htdocs/api"
    ServerName  api.test.licheepay.com
   <Directory "/usr/local/apache/htdocs/api">
    Options Indexes FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from all
    </Directory>

    ErrorLog "|/usr/local/sbin/cronolog  /usr/local/apache/logs/api/%Y-%m-%d/ErrorLog_%H.log"
    CustomLog "|/usr/local/sbin/cronolog  /usr/local/apache/logs/api/%Y-%m-%d/CustomLog_%H.log" common

    #ErrorLog "|/usr/local/apache/bin/rotatelogs  /usr/local/apache/logs/api/ErrorLog.%Y-%m-%d-%H_%M_%S.log 10M +480"
    #CustomLog "|/usr/local/apache/bin/rotatelogs  /usr/local/apache/logs/api/CustomLog.%Y-%m-%d-%H_%M_%S.log 20M +480" common
</VirtualHost>
如果是配置了虚拟域名，要在虚拟服务器上加上下面这段，具体可以参考上面 的配置就可以，还要注意的是http.conf是不是对httpd-vhost.conf这个文件包含进来了？需要检查一下

  <Directory "/usr/local/apache/htdocs/api">
    Options Indexes FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from all
    </Directory>
