如何使用SSH在另一台服务器上的PHP中运行CLI命令？ [英] How to run CLI commands in PHP on another server using SSH?

问题描述

我正在尝试在PHP中但在另一台服务器上运行CLI命令。为了在另一台服务器上运行该命令，我使用了Linux ssh 命令。为了在PHP中运行CLI命令，我使用 exec（）。

I am trying to run CLI commands in PHP but on a different server. In order to run the command on the other server I am using the linux ssh command. In order to run the CLI command in PHP I am using exec().

这可行... / p>

This works...

$output = exec('cut -d: -f1 /etc/passwd'); //works!

这可以从一台服务器的命令行到另一台服务器...

This works from the command line of one server to another...

ssh my.otherserver.com "date"

但是，当我尝试在PHP中执行此操作时...

But, when I try to do this in PHP it does not work...

$output = exec('ssh my.otherserver.com "date"'); //does not work!

我想做的是可能的吗？我该怎么做呢？预先感谢。

Is what I am trying to do possible? How do I do this? Thanks in advance.

推荐答案

ssh2_connect或phpseclib

您可以使用ssh2_connect或phpseclib。在我的EC2实例上，我必须安装ssh2_connect软件包（例如yum install php56-pecl-ssh2-0.12-5.15.amzn1.x86_64），因为默认情况下该软件包不存在。注意：这也可以使用bash脚本来完成。

You can use ssh2_connect or phpseclib. On my EC2 instance I had to install the package for ssh2_connect (e.g. yum install php56-pecl-ssh2-0.12-5.15.amzn1.x86_64) as it wasn't there by default. Note: this could be done with a bash script as well.

<?php

//ssh2_connect:
$connection = ssh2_connect('localhost', 22);
ssh2_auth_password($connection, 'user', 'password');
$stream = ssh2_exec($connection, 'ls -l > /tmp/worked.txt');

//phpseclib:
include('Net/SSH2.php');
$ssh = new Net_SSH2('www.example.com');
$ssh->login('username', 'password') or die("Login failed");
echo $ssh->exec('command');
