php - SSH Connection to a remote server using PHP

Question

I want to make a SSH connection to a remote server using php.

Im using php 5.3 on Linux/CEntOS.

What I have done so far :

$connection = ssh2_connect('192.168.1.22', 22);
ssh2_auth_password($connection, '_username', '_password');
$stream = ssh2_exec($connection, 'ls -l');

But I'm getting this error :

Fatal error: Call to undefined function ssh2_connect()

So, my questions are :

1. Are ssh2_* functions not installed by default in php?

2. Do I need an extension or library for using these functions?

3. How can I solve this problem ?

Answer 1

您可以配置您的服务器（Ubuntu）：

sudo apt-get install libssh2-php
sudo service apache2 restart

Answer 2

phpseclib

• 从这里或 这里下载（直接链接），

• 将其包含到项目中，

接着 ：

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

Answer 3

ssh_* 函数并非默认安装在 php 核心中。您必须使用 pecl 添加它们，有关详细说明，请参阅 php 手册：http: //de1.php.net/manual/en/ssh2.installation.php
