通过PHP启动远程服务

基本上，我想通过PHP

ssh2\u connect

函数将不同的命令传递给服务器。但我需要使用不同的按钮来传递不同的命令，但无法完成

下面是我的按钮代码：

<?php
$connection = ssh2_connect('ipaddress', 22);
ssh2_auth_password($connection, 'root', 'password');

if (isset($_POST['button'])) ssh2_exec($stream = ssh2_exec($connection, 'systemctl stop apache2'));
?>
<form action="" method="post">
<button type="submit" name="button">Apache2</button

Apache2有几件事：


您的代码没有完成，它缺少HTML的其余部分
您的嵌套
ssh2\u exec（$stream=ssh2\u exec（
），很可能是输入错误
你停止的apache没有启动它

以下内容将帮助您开始，希望对您有所帮助

<?php
class ssh {

    public function __construct($ip, $user, $pass, $port = 22)
    {
        // connect
        $this->connection = ssh2_connect($ip, $port);
        ssh2_auth_password($this->connection, $user, $pass);
    }

    public function exec($cmd = null)
    {
        // define streams
        $this->stream = ssh2_exec($this->connection, $cmd);
        $this->err_stream = ssh2_fetch_stream($this->stream, SSH2_STREAM_STDERR);

        // get streams
        $this->output = stream_get_contents($this->stream);
        $this->error = stream_get_contents($this->err_stream);

        return $this;
    }
}

// define cmds
$commands = [
    'stop_apache' => [
        'description' => 'Stop Apache2',
        'cmd' => 'systemctl stop apache2'
    ],
    'restart_apache' => [
        'description' => 'Restart Apache2',
        'cmd' => 'systemctl restart apache2'
    ],
    'start_apache' => [
        'description' => 'Start Apache2',
        'cmd' => 'systemctl start apache2'
    ]
];

// handle post
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $error = [];
    $result = '';

    // validate input
    if (empty($_POST['service'])) {
        $error = [
            'service' => 'Service type required!'    
        ];
    } elseif (!array_key_exists($_POST['service'], $commands)) {
        $error = [
            'service' => 'Invalid Service!'    
        ];
    }

    // run cmd - $result->output will have stdout, $result->error will have stderr
    if (empty($error)) {
        $ssh = new ssh('127.0.0.1', 'root', 'password');
        $result = $ssh->exec($commands[$_POST['service']]['cmd']);
    }
}
?>

<form action="" method="post">
    <?php if (!empty($error)): ?>
    <h3>Error</h3>
    <pre><?= print_r($error, true) ?></pre>
    <?php endif ?>

    <?php foreach ($commands as $key => $command): ?>
    <button type="submit" name="service" value="<?= $key ?>"><?= $command['description'] ?></button>
    <?php endforeach ?>
</form>

<?php if (!empty($result)): ?>
<pre><?= print_r($result, true) ?></pre>
<?php endif ?>


错误
完美，它正在工作…我已经使用上面的code.np添加了更多的服务，很高兴它起到了作用和帮助。感谢接受。如果我想显示通过该代码执行的命令的输出，我该怎么办？正如代码中所述，
$result->output
将有stdout，
$result->error
将有stderr，不要混淆它虽然您需要使用管道和WebSocket来实现这一点。对。实际上，它仍然没有显示输出。我使用的是PHP5.6，这不是问题吗？但是当我在PHP7上测试时，它显示了输出。
<?php
class ssh {

    public function __construct($ip, $user, $pass, $port = 22)
    {
        // connect
        $this->connection = ssh2_connect($ip, $port);
        ssh2_auth_password($this->connection, $user, $pass);
    }

    public function exec($cmd = null)
    {
        // define streams
        $this->stream = ssh2_exec($this->connection, $cmd);
        $this->err_stream = ssh2_fetch_stream($this->stream, SSH2_STREAM_STDERR);

        // get streams
        $this->output = stream_get_contents($this->stream);
        $this->error = stream_get_contents($this->err_stream);

        return $this;
    }
