如何使用PHP分別運行2個SSH命令？

Question

我想通過PHP使用SSH連接來運行Bash腳本。

我寫了一個腳本來進行備份和恢復的MySQL數據庫和我還在測試，以實現這一目標。我在嘗試 運行兩個不同的簡單命令時遇到了問題。我的代碼是：

<?php 
if (!function_exists("ssh2_connect")) die("function ssh2_connect doesn't exist"); 

if(!($con = ssh2_connect("server.hosting.com", 22))){ 
    echo "fail: unable to establish connection\n"; 
} else { 

    if(!ssh2_auth_password($con, "username", "password")) { 
     echo "fail: unable to authenticate\n"; 
    } else { 
     // allright, we're in! 
     echo "okay: logged in...\n"; 




     if (!($stream = ssh2_exec($con, "cd directory "))) { 
      echo "fail: unable to execute command\n"; 
     } else { 
      // collect returning data from command 
      stream_set_blocking($stream, true); 
      $data = ""; 
      while ($buf = fread($stream,4096)) { 
       $data .= $buf; 
      } 
      fclose($stream); 
     } 
if (!($stream = ssh2_exec($con, "mkdir directiry2"))) { 
      echo "fail: unable to execute command\n"; 
     } else { 
      // collect returning data from command 
      stream_set_blocking($stream, true); 
      $data = ""; 
      while ($buf = fread($stream,4096)) { 
       $data .= $buf; 
      } 
      fclose($stream); 
     } 
    } 
} 
?> 

它仍然創建另一個目錄，但不在「目錄」裏面！ 請幫忙!!!

的問題是，當你做CD的「狀態」之後丟失。該phpseclib文檔詳細說明：

http://phpseclib.sourceforge.net/ssh/examples.html#chdir，

如果你想能夠cd到一個目錄，然後在該目錄中，你可以鏈的東西做的東西。例如。 $ssh->exec('cd directory; mkdir directiry2');
