通过PHP启动远程服务 [英] Start remote service through PHP
本文介绍了通过PHP启动远程服务的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
基本上,我想通过PHP ssh2_connect
函数将不同的命令传递给服务器.但是我需要通过对不同的命令使用不同的按钮来传递它,但是却无法做到.
Basically i want to pass different commands to the server through PHP ssh2_connect
function. But i need to pass it through using different buttons for different commands, But unable to do it.
下面是带有按钮的代码:
Below is my code with button:
<?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
无需按钮即可工作的代码:
Code working without button:
<?php
$connection = ssh2_connect('ipaddress', 22);
ssh2_auth_password($connection, 'root', 'password');
$stream = ssh2_exec($connection, 'systemctl stop apache2');
推荐答案
以下几点:
- 您的代码尚未完成,缺少了HTML的其余部分.
- 您的嵌套
ssh2_exec($stream = ssh2_exec(
,很可能是拼写错误. - 您停止使用的Apache无法启动.
- Your codes not finished, it missing the rest of the HTML.
- Your nesting
ssh2_exec($stream = ssh2_exec(
, most likely a typo. - Your stopping apache not starting it.
以下内容将帮助您入门,希望对您有所帮助.
The following will get you started, hope it helps.
<?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 ?>
