Question

我已将我的公钥添加到EC2中的authorized_keys。但是在我明确提到要使用的私钥之前，我无法进入它。

$ sudo ssh -v ubuntu@xx.xx.xx.xx
OpenSSH_6.6.1, OpenSSL 1.0.1f 6 Jan 2014
debug1: Reading configuration data /etc/ssh/ssh_config

可能出现的错误是什么？

Answer 1

根据跟踪，允许的身份验证方案是使用公钥文件（扩展名：.pem）。您可以在实例详细信息页面中列出的EC2控制台选项卡中找到它。因此登录的正确方法是：

ssh -i <public key file> ubuntu@xx.xx.xx.xx

无法ssh到Amazon EC2实例
