我正在尝试从 Linux Mint 计算机通过 ssh 连接到我的 RHEL EC2 实例，当我运行以下命令时：
ssh ec2-user@SERVER_IP_ADDRESS
我收到此错误：
Permission denied (publickey,gssapi-keyex,gssapi-with-mic).
为了获取更多信息，我添加了 -v 标志，并得到了以下输出：

如何才能成功连接到我的 EC2 实例？
答案1
madeddie 在他们的最后一条评论中给了我一个答案：停止实例，分离 EBS 卷，然后将 EBS 卷附加到另一个实例。
答案2
您需要指定密钥（文件）的完整路径，包括文件名，即（C:{密钥所在的目录}:{keyname.pem}
错误：E:\360Pan\MySync\360Pan\CorePlay\PyWeb\AmazonAWSMyweb建站门户网站\ssh登录密钥\123.pem
右键：D:\360Pan\MySync\360Pan\CorePlay\PyWeb\AmazonAWSMyweb建站门户网站\ssh登录密钥\123.pem
