amazon-web-services - 如何通过 SSH 连接到 Redhat EC2 实例？

Question

我已阅读 AWS docs这说我应该使用:

ssh -i /path/my-key-pair.pemmy-instance-user-name@my-instance-public-dns-name

但我不知道 my-instance-user-name 应该是什么。

---

对于 Ubuntu，我总是这样做

ssh -i /path/my-key-pair.pem ubuntu@my-instance-public-dns-name

通过chmod 400/path/my-key-pair.pem更改我的 key 的权限后
