--os-shell不成功，但爆出了路径，把源代码下来看了看
D__phpnow_htdocs_jobview.php

<?php  
require_once("global.php");
$id=$_GET['id'];
$exes="select * from jobinfotable where jid=".$id."";
$rss=mysql_query($exes);

顺藤摸瓜，找到了数据库配置
D__phpnow_htdocs_kf8inc_Kf8connFile.inc.php

<?php 
  $mysql_server_name='localhost';
   $mysql_username='root';
   $mysql_password=xxx;
   $mysql_database='gzjtw'; 
...
