SAE域名绑定后,宕机时自动修改A记录并飞信通知

本文最后更新于2014年4月1日,已超过两年没有更新,如果文章内容失效,请反馈给我们,谢谢!

SAE域名绑定之后,一般是用CNAME方式将域名绑定到应用中。但是有时候我们需要用到A记录(比如说根域名,虽然在DNSPOD上可以设置CNAME记录,但很可能会影响到MX记录),而SAE的IP地址经常改变,ping应用二级域名得到的IP没多久就失效了(前些天网站因此几天打不开都没发现,我用的是教育网,自己能打开,但是电信线路变了)。还好DNSPOD有个功能叫D监控,可以帮你监控网站能否正常打开。如果发现宕机,DNSPOD会用邮件、短信、微信等方式提醒你。这里用到的是它的另一个通知方式,那就是URL回调。

“通过DNSPod 提供的D监控 URL 回调功能,您可以让宕机或恢复信息提交到您指定的 URL 上,从而更加灵活地处理各种通知信息。”

我们可以通过宕机之后的URL回调取得相关参数,并通过DNSPOD API实现自动修改记录的功能,再通过飞信发送宕机通知。

代码在后面,先说设置方法:
 

设置方法

1.点此下载代码,修改其中的参数为你自己的。

2.将代码上传到网站。

3.在DNSPOD开启D监控,在通知设置中回调URL一栏填入monitorCallback.php的地址,如http://blog.gimhoy.com/monitorCallback.php?rHost=hipic.sinaapp.com.其中rHost是SAE的二级域名。并设置回调密钥。

4.Enjoy~
