Heroku Godaddy裸域 [英] Heroku Godaddy naked domain

问题描述

我有一个Heroku应用程序，并且添加了一个CNAME(www到herokuapp)以将其从GoDaddy重定向到Heroku.现在，我也在尝试管理裸域.

I have a Heroku app and I've add a CNAME (www to herokuapp) to redirect it from GoDaddy to Heroku. Now I'm trying to manage also the naked domain.

这来自 Heroku文档.

裸域(也称为裸域或顶点域，例如 mydomain.com )必须使用DNS A记录.要设置您的根域，请使用您的DNS管理工具为以下每个地址添加单独的A记录:

Naked domains (also known as bare domains or apex domains, for example mydomain.com) must use DNS A-records. To setup your root domain, add separate A records for each of the following addresses using your DNS management tool:

75.101.163.44
75.101.145.87
174.129.212.2

使用主机"命令检查您的DNS是否正确配置:

Check that your DNS is configured correctly with the "host" command:

$ host example.com
example.com has address 75.101.163.44
example.com has address 75.101.145.87
example.com has address 174.129.212.2

我还从GoDaddy主菜单激活了转发功能.

I've also activated the forwarding from the GoDaddy main menu.

好吧，如果我在我的域中尝试 host example.com ，一切正常. 但是，当我尝试使用浏览器时，我得到了:

Ok, if I try host example.com with my domain, all is ok. But, when I try with the browser, I get this:

Heroku |没有这样的应用程序在该主机名上没有配置任何应用程序. 应用所有者可能已将其重命名，或者您输入了错误的网址

Heroku | No such app There is no app configured at that hostname. Perhaps the app owner has renamed it, or you mistyped the URL

我也尝试使用命令heroku domains:add yourdomain.com 但这会创建我的应用程序的第二个实例，它不会将其重定向到完整域www

I tried also with the command heroku domains:add yourdomain.com but this create a second instance of my app, it doesn't redirect it to the full domain www

推荐答案

Heroku 强烈建议使用A记录将域指向云应用.使用A记录会增加DNS解析不稳定的机会. Heroku在此处中详细介绍>.

Heroku highly advises against using A-records to point domains at cloud apps. Using A-records increases the chance of instability for DNS resolution. Heroku goes into details here.

相反，您应该将裸域重定向到"www"子域.您可以参考此SO线程了解有关如何设置的更多详细信息在GoDaddy上.

Instead, you should redirect your naked domain to the 'www' subdomain. You can refer to this SO thread for more details on how to set that up on GoDaddy.
