我尝试通过ssh和pipe通信两台机器,以便从一台机器到另一台机器之间收到消息。 第二个使用sdtin从第一台机器读取消息并在文本文件中写入。
我有一台机器,我有这个程序,但它不起作用......
$message = "Hello Boy";
$action = ('ssh root@machineTwo script.php');
$handle = popen($action, 'w');
if($handle){
echo $message;
pclose($handle);
}
在另一台机器上,机器我有:
$filename = "test.txt";
if(!$fd = fopen($filename, "w");
echo "error";
}
else {
$action = fgets(STDIN);
fwrite($fd, $action);
/*On ferme le fichier*/
fclose($fd);}

这是最简单的方法(使用phpseclib, a pure PHP SSH2 implementation):
<?php
include('Net/SSH2.php');
$ssh = new Net_SSH2('www.domain.tld');
if (!$ssh->login('username', 'password')) {
exit('Login Failed');
}
echo $ssh->exec('php script.php');
?>
使用RSA私钥:
<?php
include('Net/SSH2.php');
$ssh = new Net_SSH2('www.domain.tld');
$key = new Crypt_RSA();
$key->loadKey(file_get_contents('privatekey'));
if (!$ssh->login('username', $key)) {
exit('Login Failed');
}
echo $ssh->exec('php script.php');
?>
如果script.php侦听stdin,你可以read() / write()或使用enablePTY()

此解决方案正在运行:
MACHINE ONE
在使用ssh连接到 MACHINE TWO 后,我向 MACHINE TWO 发送消息。我使用popen
和fwrite
//MACHINE ONE
$message = "Hello Boy";
$action = ('ssh root@machineTwo script.php'); //conection by ssh-rsa
$handle = popen($action, 'w'); //pipe open between machineOne & two
if($handle){
fwrite($handle, $message); //write in machineTwo
pclose($handle);
}
MACHINE TWO
我用fopen
打开一个文件,并使用 fgets(STDIN); 获取 MACHINE ONE 的消息。我在打开的文件中写了这条消息。
//MACHINETWO
$filename = "test.txt";
if(!$fd = fopen($filename, "w");
echo "error";
}
else
{
$message = fgets(STDIN);
fwrite($fd, $message); //text.txt have now Hello World !
/*we close the file*/
fclose($fd);
}

Popen主要用于使用&#34;管道文件&#34;进行两个本地程序通信。
要实现您的目标,您应该尝试使用SSH2 PHP库(一个有趣的链接http://kvz.io/blog/2007/07/24/make-ssh-connections-with-php/)
在你的情况下,你会在machineOne上为你的php脚本做类似的事情:
if (!function_exists("ssh2_connect")) die("function ssh2_connect doesn't exist");
if (!($con = ssh2_connect("machineTwo", 22))) {
echo "fail: unable to establish connection\n";
} else {
if (!ssh2_auth_password($con, "root", "yourpass")) {
echo "fail: unable to authenticate\n";
} else {
echo "okay: logged in...\n";
if (!($stream = ssh2_exec($con, "php script.php"))) { //execute php script on machineTwo
echo "fail executing command\n";
} else {
// collect returning data from command
stream_set_blocking($stream, true);
$data = "";
while ($buf = fread($stream,4096)) {
$data .= $buf;
}
fclose($stream);
echo $data; //text returned by your script.php
}
}
}
我认为你有充分的理由这样做,但为什么要使用PHP?
