我使用phpseclib从php调用ssh命令。
$ip = 'ip_address';
$login = 'user';
$password = 'password';
$ssh = new SSH2($ip);
$ssh->login($login, $password);
在下面的示例中,一切正常(因为我不需要权限):
$command = 'ifconfig';
$result = $ssh->exec($command); // result = 'eth0 ..., eth1 etc.'
下一个例子中出现问题:
$command = 'ip addr flush dev eth1';
$result = $ssh->exec($command); // result = 'Failed to send flush request: Operation not permitted'
我尝试使用sudo su登录:
$result = $ssh->read('$'); // result = '..... user@hostname:~$'
$result = $ssh->write("sudo su\n"); //result = true
$result = $ssh->read(':'); // result = 'sudo su\n [sudo] password for user:'
$result = $ssh->write($password."\n"); // result = true
$result = $ssh->read('#'); //result = 'root@hostname:/home/user#
似乎一切都还好(我在根上),但是:
$command = 'ip addr flush dev eth1';
$result = $ssh->exec($command); // result = 'Failed to send flush request: Operation not permitted'
哪里有问题?提前谢谢!

我使用了http://mrbluecoat.blogspot.com/2014/03/running-sudo-commands-with-phpseclib.html中的以下代码:
$ssh->read('/.*@.*[$|#]/', NET_SSH2_READ_REGEX);
$ssh->write("sudo YOUR COMMAND HERE\n");
$ssh->setTimeout(10);
$output = $ssh->read('/.*@.*[$|#]|.*[pP]assword.*/', NET_SSH2_READ_REGEX);
if (preg_match('/.*[pP]assword.*/', $output)) {
$ssh->write($sudo_password."\n");
$ssh->read('/.*@.*[$|#]/', NET_SSH2_READ_REGEX);
}
它有效!

您需要将httpd进程(apache,php)添加到root用户组。辅助进程可以使用root perm运行。
