'www' CNAME 无法正确解析，但根 A 记录工作正常（对于 Heroku）

发布于 2024-10-31 10:10:11 字数 1173 浏览 4 评论 0原文

我在使用 WHM/Cpanel 为我的 heroku 应用程序设置 CNAME 记录时遇到问题。

我已按如下方式设置记录 - 查看图像链接。

dapcards.com 正在解析 Heroku 应用程序，没有任何问题。

但是，www.dapcards.com 失败：

> host dapcards.com
dapcards.com has address 75.101.145.87
dapcards.com has address 75.101.163.44
dapcards.com has address 174.129.212.2
dapcards.com mail is handled by 0 dapcards.com.
> host www.dapcards.com
Host www.dapcards.com not found: 3(NXDOMAIN)
Host www.dapcards.com not found: 3(NXDOMAIN)

当我使用 dnsstuff.com 工具时，它似乎可以很好地访问 proxy.heroku.com，但会产生错误：

[BOGUS ANSWER: This server is not authoritative for proxy.heroku.com.: 
it refers back to the root servers]

http://www.dnsstuff.com/tools/legacy/?formaction=DNSLOOKUP&ToolFormName=customlookup&name=www.dapcards.com&r=235660&detail=0&type=CNAME

我显然在这里遗漏了一些东西。有人有什么想法吗？非常感谢一些建议！

干杯，抢

I'm having trouble using WHM/Cpanel to set up CNAME records for my heroku app.

I've set up the records as follows - see link to image.

dapcards.com is resolving to the heroku app with no problems.

However, www.dapcards.com fails:

> host dapcards.com
dapcards.com has address 75.101.145.87
dapcards.com has address 75.101.163.44
dapcards.com has address 174.129.212.2
dapcards.com mail is handled by 0 dapcards.com.
> host www.dapcards.com
Host www.dapcards.com not found: 3(NXDOMAIN)
Host www.dapcards.com not found: 3(NXDOMAIN)

When I use the dnsstuff.com tool, it seems to get to proxy.heroku.com fine, but produces an error:

[BOGUS ANSWER: This server is not authoritative for proxy.heroku.com.: 
it refers back to the root servers]

http://www.dnsstuff.com/tools/legacy/?formaction=DNSLOOKUP&ToolFormName=customlookup&name=www.dapcards.com&r=235660&detail=0&type=CNAME

I'm obviously missing something here. Has anyone got any ideas? Would really appreciate some advice!

Cheers,
Rob

也许您没有等待 DNS 传播足够长的时间？这里看起来不错：

$ host www.dapcards.com
www.dapcards.com is an alias for proxy.heroku.com.
proxy.heroku.com has address 50.16.233.102
proxy.heroku.com has address 174.129.212.2
proxy.heroku.com has address 75.101.145.87
$ host dapcards.com
dapcards.com has address 75.101.145.87
dapcards.com has address 75.101.163.44
dapcards.com has address 174.129.212.2
dapcards.com mail is handled by 0 dapcards.com.

Perhaps you didn't wait long enough for DNS to propagate? Looks fine here:

$ host www.dapcards.com
www.dapcards.com is an alias for proxy.heroku.com.
proxy.heroku.com has address 50.16.233.102
proxy.heroku.com has address 174.129.212.2
proxy.heroku.com has address 75.101.145.87
$ host dapcards.com
dapcards.com has address 75.101.145.87
dapcards.com has address 75.101.163.44
dapcards.com has address 174.129.212.2
dapcards.com mail is handled by 0 dapcards.com.
