PHP 获取linux服务器性能CPU、内存、硬盘、进程等使用率

数据库配置文件： conn.php
<?php

define("DB_SERVER", "172.16.7.2");       //存放数据的服务器IP地址
define("DB_USER", "root");
define("DB_PWD","111111");
define("DB_NMAE","performance");

   die('连接数据库失败: ' . mysql_error());
  }
  $flag = mysql_select_db($db_name,$conn);
  if(!$flag){
   echo "<p align='center'>数据库连接出错!</p>";exit();
  }else{
   mysql_query("SET NAMES UTF8");
  }
