Amazon ec2 EC2&x2B；ssh:权限被拒绝（公钥）

我第一次在AWS上打开了一个新的EC2实例。但是，我不能SSH到它，因为它给我

拒绝权限（公钥）

可能是因为我没有对

new.pem

文件做任何操作？？我应该如何处理我的

new.pem

文件

尝试ssh-i new.pem ec2-user@your-ip假定它是Amazon Linux发行版

您需要使用

user@IP

或

-l user

语法按用户您是指我的IAM用户吗？我更新了bottomNo上的问题，bottomNo是登录新EC2实例的用户名。亚马逊的默认值是

ec2用户

，正如Harry所建议的，很好用！！那么现在我是否直接从控制台创建用户？我以为我刚刚创建的IAM用户组+用户会出现（尽管我在创建实例后才创建）？值得一看：嘿，Harry，我更新了我的问题，尝试了你的方法。。没有work@Edmund尝试使用

ec2用户

，而不是您登录计算机时使用的用户名，而是创建Amazon AMImage的人使用的用户名，该用户名通常是

ec2用户

您的根密钥（new.pem）引用ec2用户。所以您需要使用ssh-i new.pem ec2 user@

Nets-Mac-Pro:Downloads emai$ ssh -i new.pem emai@54.88.57.225
