如何通过PHP调用远程Shell脚本_PHP远程Shell脚本调用与SSH安全连接教程

<?php
$connection = ssh2_connect('192.168.1.100', 22);
if (!$connection) {
    die('无法连接到远程服务器');
}
<p>// 用户名密码认证（也可使用公钥）
if (!ssh2_auth_password($connection, 'username', 'password')) {
die('认证失败');
}</p><p>// 执行远程Shell脚本
$stream = ssh2_exec($connection, '/path/to/your/script.sh');
stream_set_blocking($stream, true);
$output = stream_get_contents($stream);</p><p>echo "脚本输出：\n";
echo $output;</p><p>fclose($stream);
?>
