sudo php 权限
我想通过速度 实现 ifconfig eth0 down 我看到 一些关于sudo获取权限的文章 我是如下写的代码 但是没有效果 求高手指点
首先我 visudo 

然后在 # Allow members of group sudo to execute any command添加如下代码
shenwenjian ALL=NOPASSWD:/sbin/ficonfig

然后保存 

PHP编码如下
  $inf=shell_exec("/var/lib/sudo/sbin/ifconfig eth0 down");
  print_r($inf)

求高手指点这个 sudo 获取权限的问题在哪 谢谢

------解决方案--------------------
$inf=shell_exec("sudo -u root -S /var/lib/sudo/sbin/ifconfig eth0 down");
这样试试呢?
