我已经阅读了该主题的现有答案，但似乎仍然无法连接。我创建了一个 AWS 密钥并将其保存到我的 ~/.ssh 文件夹中。
命令：
ssh -i ~/.ssh/jdrake.pem [email protected] -v
结果是：
OpenSSH_5.2p1, OpenSSL 0.9.8r 8 Feb 2011

我也尝试过不同的用户（ubuntu、root、jdrake），但没有成功。我在 OSX 上。
答案1
从上面的日志可以看出您正在连接到一台 Ubuntu 机器：
debug1: Remote protocol version 2.0, remote software version OpenSSH_5.3p1 Debian-3ubuntu7
因此该框的默认用户名将是ubuntu，而不是ec2-user仅适用于 Amazon Linux。
答案2
关闭这个，因为这已经是三年前的事情了，我不记得最终的解决方案了。
