amazon-web-services - 将 Amazon CloudFront 指向 A 记录而不是 CNAME

Question

我找到了将我的域的 CNAME 指向 Amazon 的 CloudFront 服务的说明，但理想情况下我希望指向根名称(A 记录名称)。例如，example.com 而不是 www.example.com 。这可能吗？

Answer 1

您可以使用 Route 53 服务将区域顶点(即 example.com)指向 AWS 上的 CloudFront 分配。只需登录您的 CloudFront 分配并将备用域名 (CNAME) 设置为您的域(例如 example.com 和/或 www.example.com)。然后在 Route 53 中，为您的域创建一个托管区域，然后创建一个别名记录，选择 CloudFront 分配作为目标。您还可以为任何子域创建第二个别名记录，例如 www.example.com。注意:您还需要通过域名注册商更改名称服务器。

Q. Can I point my zone apex (example.com versus www.example.com) at my Amazon CloudFront distribution?

Yes. Amazon Route 53 offers a special type of record called an ‘Alias’ record that lets you map your zone apex (example.com) DNS name to your Amazon CloudFront distribution (for example, d123.cloudfront.net). IP addresses associated with Amazon CloudFront endpoints vary based on your end user’s location (in order to direct the end user to the nearest CloudFront edge location) and can change at any time due to scaling up, scaling down, or software updates. Route 53 responds to each request for an Alias record with the IP address(es) for the distribution. Route 53 doesn't charge for queries to Alias records that are mapped to a CloudFront distribution. These queries are listed as “Intra-AWS-DNS-Queries” on the Amazon Route 53 usage report.
