[英]Domain + AWS EC2: How to make www.mydomain.com point to my EC2 server?
问题描述
I'm trying to create a website and I just bought a domain at domain.com. 
我正在尝试创建一个网站，我刚刚在domain.com上购买了一个域名。 I also launched an EC2 instance in AWS. 我还在AWS中启动了一个EC2实例。 Which one of the options would I choose below so that going to www.edmundscoolsite.com would point to my EC2 instance? 我将在下面选择哪一个选项，以便访问www.edmundscoolsite.com指向我的EC2实例？

There are actually a couple of options here. 这里有几个选项。
The best option is to associate an elastic IP address with your EC2 instance, then use an A record. 最好的选择是将弹性IP地址与EC2实例相关联，然后使用A记录。 The EIP is yours until you release it, even if you replace your instance. EIP是你的，直到你发布它，即使你更换你的实例。
An alternative option is to make www.edmundscoolsite.com a CNAME record whose value is the public DNS for your EC2 instance, something like ec2-1-2-3-4.us-west-2.compute.amazonaws.com . 另一种选择是让www.edmundscoolsite.com成为CNAME记录，其值为EC2实例的公共DNS，类似于ec2-1-2-3-4.us-west-2.compute.amazonaws.com 。 When you replace your EC2 instance the CNAME will no longer be valid, however, which is why the first option is better. 当您替换EC2实例时，CNAME将不再有效，这就是为什么第一个选项更好。
