下面来看一个关于PHP调用Linux命令无权限的问题解决(visudo),希望文章对大家有帮助.

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);

测试结果为没有权限

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

解决步骤:

$ visudo

1)注释以下行

#Defaults    requiretty

2)在文件末尾加入以下

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

最后测试结果:

Array ( [0] => Warning: memory is too small: 1044725760 [1] => test configure is ok )
