业务背景: yourcmd为我的linux程序,它对权限要求非常严格,当用php去执行yourcmd程序
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
Array ( [0] => Warning: memory is too small: 1044725760 [1] => test configure is ok )
