March 16th, 2009, 10:57 am| Posted in 域名主机

这两天有点事，所以更新停了一天。上回中说到我们有了域名，如何做DNS域名解析。其中讲了一下基本的情况，但是无错不在，就算我们懂得了基本操作，但是在一起大意，疏忽下，还是会遇到一些预想不到的问题。下面我就来说说，我所遇见的几种情况，以及如何解决的。

问题一：域名解析正确，但是还是无法打开域名。注：域名解析生效是要时间的，你是否等待了一定的时间了呢？还有就是更换了DNS服务器，没有重新解析过，一般换了DNS服务器，域名解析要重做的。

问题二：绑定的同一IP,顶级域名不能正常访问,而带www的顶级域名却可以。注：一般情况是你之解析了一个，请看上一篇文章，两个地址是否带WWW，都有同时解析。还有因第三种情况引起。

问题三：有时能访问，有时打开出现如下情况：

Great Success !

ATTENTION!
If you are seeing this page instead of the site you expected, please contact the administrator of the site involved. (Try sending an email to <webmaster@domain>.) Although this site is running cPanel, WebHost Manager, and Apache software it almost certainly has no other connection to cPanel Inc. or the Apache Group. Please do not send mail about this site or its contents to cPanel Inc. or the Apache Group.

Apache is working on your cPanel? and WHM? Server
If you can see this page, then the people who manage this server have installed cPanel and WebHost Manager (WHM) which use the Apache Web server software and the Apache Interface to OpenSSL (mod_ssl) successfully. They now have to add content to this directory and replace this placeholder page, or else point the server at their real content.
