[背景]原来对端口的监控是用nagios的，今天，看了php的fsockopen，就感觉用它可以做点事喽。。。。
[过程]
先给大家一张图
代码如下：
<?PHP
require_once('adodb/adodb.inc.php');
$db_type = 'mysql';
$db_host = 'localhost';
$db_user = 'cdnnode';
$db_pass = 'xxxxxxxxx';
$db_name = 'cdnode';
$GLOBALS['MY_SESS_CONN'] =& ADONewConnection($db_type);
$GLOBALS['MY_SESS_CONN']->Connect( $db_host, $db_user, $db_pass, $db_name);
if (! $MY_SESS_CONN){
echo "Unable to connect to DB: " . mysql_error();
exit;
}
$sql = "SELECT ip,port from nodes";
$result = mysql_query($sql);
if (!$result) {
echo "Could not successfully run query ($sql) from DB: " . mysql_error();
exit;
}
if (mysql_num_rows($result) == 0) {
echo "No rows found, nothing to print so am exiting";
exit;
}
?>
<html><head>
<meta http-equiv=refresh content="30">
<title>CDN NODES Monitors!</title>
</head>
<body>
<h1 align="center">CDN Nodes Status</h1>
<hr noshade>
<?php
echo "<table width=80% align='center' border='1'><tr>";
$i=0;
while ($row = mysql_fetch_assoc($result)) {
if($i%4 == 0){
echo "</tr><tr>";
}
echo "<td><div align='center'>$row[ip]</td>";
$res = @fsockopen($row[ip],$row[port],$errno,$errstr,2);
if($res)
{
echo "<td><div align='center'><font color=\"#33CC66\"><b>OK!</b></font></div></td>";
}
else
{
echo "<td><div align='center'><font color=\"#FF0000\"><blink><b>Fail!</b></blink></font></div></td>";
}
$i+=1;
}
echo "</tr></table>";
mysql_free_result($result);
?>
</body></html>

感觉如何，大家也试试吧！
