我在OpsWorks中有2个实例。 第一个我可以使用ssh登录。 第二个，如果我添加一个EBS卷，并将其挂载到“/ mnt / data”或其他任何地方，当我尝试登录时，我得到：
"Permission Denied (publickey)"
到ssh我用：
"ssh -v ubuntu@10.0.2.184"
这是完整的日志：

如果我没有安装EBS卷，那么它就可以正常登录。
我该如何解决这个问题？
答案 0 :(得分：0)
如果它是Amazon Linux EC2实例，那么您应该以 ec2-user 用户身份登录，而不是以 ubuntu 用户身份登录。所以，ssh -v ec2-user@10.0.2.184。
