EC2 인스턴스를 생성하고 올바르게 ssh 할 수있었습니다.ssh에서 ec2 로의 퍼미션 거부 (공개 키)

는 나는 내가 11을 제거하는 것이 내가 솔루션을 통해 고개를 제안

It is also possible that a host key has just been changed.

다음과 같은 오류를 가지고 다시 시작한 후 인스턴스를

을 중지 known_hosts의 항목입니다. 그 후 다음 오류가 발생합니다.

인스턴스를 중지 한 경우 새 IP 주소 또는 이전 IP 주소에 연결을 시도 했습니까? ec2에서 인스턴스를 중지하면 인스턴스가 다시 시작할 때 새 IP 주소를 얻게됩니다.
