推荐答案

如果您已经安装博托，您可以添加/更新DNS设置：

If you have installed boto, you can add / update DNS settings like this:

DNS_ADDRESS="`ec2metadata | grep 'public-hostname:' | cut -d ' ' -f 2`"
/usr/local/bin/route53 change_record <Hosted zone ID> foo.bar.com. CNAME $DNS_ADDRESS 300

DNS_ADDRESS 是实例的AWS DNS名称，如 ec2-1-2-3-4.eu-西1.compute.amazonaws。 COM 的

DNS_ADDRESS is the AWS DNS name of the instance such as ec2-1-2-3-4.eu-west-1.compute.amazonaws.com

第二行创建了5分钟TTL一个CNAME。您需要添加要更改域的托管区域ID。

The second line creates a CNAME with 5min TTL. You need to add the hosted zone ID of the domain you want to change.

如果你把这个片段到的/etc/rc.local ，该实例会自动更新/创建CNAME时，它的启动。

If you put this snippet into /etc/rc.local, the instance will automatically update / create the CNAME when it's booting.

我不知道你有私DNS的意思。 Route53提供了一个（公共）DNS服务。但是，如果你的情况是VPC里面有没有危害，使DNS条目公众，因为没有人可以反正访问它们。

I'm not sure what you mean with "private" DNS. Route53 provides a (public) DNS service. However, if your instances are inside a VPC there's no harm to make the DNS entries public, since no one can access them anyway.
