다음 명령을 사용하여 Ubuntu 14.04 시스템에서 ssh와 함께 사용할 키를 생성했습니다.
ssh-keygen -t rsa -b 2048
openssl rsa -in id_rsa -outform pem > pk_rsa.pem
openssl rsa -in pk_rsa.pem -pubout -out my_key.pem
my_key.pem을 로컬 OSX에 복사했습니다. 다음 명령을 사용하여 Ubuntu에 SSH로 접속해 보십시오.
ssh -v -i ./my_key.pem [email protected]

이 문제를 해결할 방법이 있나요?
답변1
두 가지 다른 기술을 혼동하고 openssh있습니다 openssl. 전자 만 필요한 것 같습니다.
SSH 키 쌍을 이미 생성했으므로 SSH를 사용하려는 서버에 공개 키를 복사하기만 하면 됩니다. 올바른 방법은 다음과 같습니다
$ ssh-copy-id username@<server-ip>
바꾸다사용자 이름그리고<서버 IP> 서버의 사용자 및 IP 주소를 사용하십시오.
