我陷入了问题。我不知道为什么会遇到这个问题
问题：我无法与EC2实例连接。
错误：[email protected]：权限被拒绝（公钥）。
我遵循的步骤：
1> Take a Image(AMI) of Ec2 instance form one region.
2> Move that AMI to another region.
3> Create instance from that AMI.
4> Not able to connect with instance.
*。pem文件权限已检查，为400
**检查安全组端口22已公开打开
**尝试与root，ec2-user等其他用户连接>
详细错误是：

创建一个公共文件（使用腻子）到您的Source实例pem文件，并将该文件导入到您的目标区域密钥对，当您从AMI对该实例进行午餐时，再使用该密钥对。
