系统：CentOS 6.3

apache是php的执行用户

用exec函数去执行linux系统上的程序/usr/local/yourcmd/sbin/yourcmd

php代码如下：

<?php
$conf_file = "/var/www/html/webroot/test.tmp";
$command = "sudo /usr/local/yourcmd/sbin/yourcmd -t -f {$conf_file}";
exec($command,$out);
print_r($out);

Array ( [0] => sudo: no tty present and no askpass program specified )

$ visudo

#Defaults    requiretty

apache ALL=(ALL) NOPASSWD: ALL
Cmnd_Alias yourcmd = /usr/local/yourcmd/sbin/yourcmd
