【问题描述】:
我通过 ssh 很好地连接了我的 ec2 实例,在添加新的 EBS 卷后通过 'sudo shutdown -r now' 重新启动了机器
然后我尝试使用以下命令访问:
ssh -v -i primary_key.pem ubuntu@ec2-23-22-245-160.compute-1.amazonaws.com
如下图所示:
OpenSSH_5.6p1, OpenSSL 0.9.8r 8 Feb 2011

出了什么问题?我遗漏了什么?
【问题讨论】:
-
您是否确认您可以通过 AWS 控制台登录?从那里您还可以确保更改主机名或密钥时没有发生任何奇怪的事情。
-
是的,我已经检查过了,还导出了一个新的公钥,但它不起作用!
-
我想多指点@azizunsal,从 .ssh 文件夹中删除您的 known_hosts 文件,然后尝试 ssh 到您的实例。
