나는 정말로 여기 붙어 있습니다. 공개 키를 사용하여 로컬에서 ec2 서버로 ssh하려고했지만 작동하지 않습니다. -> 권한이 거부되었습니다 (공개 키).

로컬 : 생성 된 공개 키 쌍 및 id_rsa.pub의 복사 된 내용입니다. 원격 : PEM 파일을 사용하여 EC2 서버에 ssh-ed하고 id_rsa.pub 내용을 .ssh 폴더의 인증 된 키 파일 줄에 붙여 넣습니다.

제대로 작동해야합니까? 나는 일반적인 실수가 권한이라는 것을 알았지 만 내 것이 올바르게 설정 된 것 같습니다.

원격 권한 :

drwx------ 2 ec2-user ec2-user  4096 Jul 23 04:00 .ssh

그리고 .ssh에서 :

-rw-r--r-- 1 ec2-user ec2-user  404 Jul 24 03:19 id_rsa.pub
-rw------- 1 ec2-user ec2-user 1679 Jul 24 03:19 id_rsa
-rw------- 1 ec2-user ec2-user  529 Jul 26 20:53 authorized_keys

노동 조합 지부:

drwx------    10 robvanhaaren  staff    340 Jul 26 18:43 .ssh

그리고 .ssh에서 :

-rw-r--r--  1 robvanhaaren  staff   404 Jul 26 21:28 id_rsa.pub
-rw-------  1 robvanhaaren  staff  1766 Jul 26 21:28 id_rsa
-rw-r--r--  1 robvanhaaren  staff  5987 Jul 26 21:29 known_hosts

그러나 내가 달릴 때 :

Robs-MacBook-Air-2:.ssh robvanhaaren$ ssh ec2-54-85-62-99.compute-1.amazonaws.com -l ec2-user -v

다음을 반환합니다.

이상한 점은 다른 ec2 서버에서 서버에 공개 키를 사용하여 로그인 할 수 있다는 것입니다. 따라서 문제 는 리모컨이 아닌 로컬 컴퓨터에있는 것 같습니다 .

도와주세요!
