使用 shell_exec('passwd') 更改用户密码 [英] Using shell_exec('passwd') to change a user's password

问题描述

我需要能够通过网页(在受控环境中)更改用户的密码.因此，为此，我正在使用此代码:

I need to be able to change the users' password through a web page (in a controlled environment). So, for that, I'm using this code:

<?php
$output = shell_exec("sudo -u dummy passwd testUser testUserPassword");
$output2 = shell_exec("dummyPassword");
echo $output;
echo $output2;
echo "done";
?>

我的问题是该脚本没有更改用户testUser"的密码.我做错了什么?

My problem is that this script is not changing the password for the user "testUser". What am I doing wrong?

谢谢

推荐答案

另一种选择是有一个 shell 脚本，比如在某个地方叫做 passwd_change.sh，看起来像这样:

Another option is to have a shell script, say called passwd_change.sh somewhere that looks like this:

#!/usr/bin/expect -f
set username [lindex $argv 0]
set password [lindex $argv 1]

spawn passwd $username
expect "(current) UNIX password: " 
send "$password\r"
expect "Enter new UNIX password: "
send "$password\r"
expect "Retype new UNIX password: "
send "$password\r"
expect eof

然后在您的 php 代码中执行:

Then in your php code do:

<?php
shell_exec("sudo -u root /path/to/passwd_change.sh testUser testUserPass");
?>
