注意:我们用php来控制linux,php环境可以在windows也可以在linux,但是我们要控制的机器是一台linux(被控制的linux关闭selinux和firewalld)。
如果php在linux,不会安装没关系,可以参考安装lamp教程地址: http://blog.youkuaiyun.com/zph1234/article/details/51248124
然后我们的php环境要想实现控制linux,必须安装php的一个扩展ssh2
0.下载ssh2扩展,从http://pecl.php.net/package/ssh2,有linux扩展包,也有windows的dll,如果是php5安装ssh2-0.13或0.12扩展,php7安装1.0
1.windows中的php安装扩展,需要下载dll文件,在php.ini中引入即可
2.这里是centos中的php安装ssh2扩展,记得关闭selinux和firewalld
yum install libssh2 libssh2-devel php-devel gcc-c++
3.如果是php5安装ssh2-0.13扩展,php7安装1.0
cd ssh2-0.13/
/usr/bin/phpize
./configure --with-php-config=/usr/bin/php-config LIBS=-ldl
make
make install
4. vi /etc/php.ini
加入extension=ssh2.so
5.重启apache
6.vi test.php
<?php
//header('Content-type:textml;charset=utf8');
$host='192.168.1.115';//被控制的linux的ip
$user='root';//用户名
$passwd='root';//密码
// 链接远程服务器
$connection = ssh2_connect($host, 22);
if (!$connection) die('connection to '.$host.':22 failed');
echo 'connection OK<br/>';
// 获取验证方式并打印
$auth_methods = ssh2_auth_none($connection, $user);
// print_r( $auth_methods.'<br/>');
if (in_array('password', $auth_methods ))
{
// 通过password方式登录远程服务器
if (ssh2_auth_password($connection, $user, $passwd))
{
if(isset($_GET['caozuo']))
{
$stream = ssh2_exec($connection, "systemctl ".$_GET['caozuo']." mariadb"); // 执行php
stream_set_blocking($stream, true); // 获取执行pwd后的内容
if ($stream === FALSE) die("pwd failed");
}
$caozuo=isset($_GET['caozuo'])?$_GET['caozuo']:"";
$stream = ssh2_exec($connection, "systemctl ".$caozuo." mariadb");
echo $user.' login OK<br/>';
//服务器名称
$stream = ssh2_exec($connection, "hostname"); // 执行php
stream_set_blocking($stream, true); // 获取执行pwd后的内容
if ($stream === FALSE) die("pwd failed");
$name=stream_get_contents($stream).'<br/>';
//ip
$stream = ssh2_exec($connection, "ifconfig eno16777736 | grep \"inet \" | awk '{ print $2}'"); // 执行php
stream_set_blocking($stream, true); // 获取执行pwd后的内容
if ($stream === FALSE) die("pwd failed");
$ip= stream_get_contents($stream).'<br/>';
//运行状态
$stream = ssh2_exec($connection, "systemctl status mariadb"); // 执行php
stream_set_blocking($stream, true); // 获取执行pwd后的内容
if ($stream === FALSE) die("pwd failed");
$status=strpos(stream_get_contents($stream),'running')?'running':'dead';
}
else
{
die( $user.' login Failed<br/>');
}
}
