☑️ open .pem 키 확인하기

• 키 있는 장소로 가서 cat zzikzzikKey.pem
• 이게 바로 SSH_PRIVATE_KEY

☑️ PRIVATE 키 모양, 저장 위치

SSH_PRIVATE_KEY 는

-----BEGIN RSA PRIVATE KEY-----
…
-----END RSA PRIVATE KEY-----

이렇게 생김

• repository secret in Project > Settings > Secrets and Variables > Actions 에 저장
• Add a new secret with the name SSH_PRIVATE_KEY and paste the contents of your .pem file or private SSH key

☑️ PUBLIC 키 모양, 저장 위치

• 반면 public key는
• ssh-rsa AAAAB3… user@example.com

• 이렇게 생김

• GitHub user profile > SSH and GPG Keys에 저장해야 한다.

public key를 authorized_keys에 저장

cat ~/.ssh/zzikzzik_key.pub >> ~/.ssh/authorized_keys
~/.ssh/authorized_keys

ls -l ~/.ssh/authorized_keys

authorized_keys볼 권한이 ec2-user에게 있다는 의미

• cat해서
• 안에 public key 저장되어 있는것 확인

☑️ 권한 부여

chmod 600 ~/.ssh/zzikzzik_key
chmod 644 ~/.ssh/zzikzzik_key.pub
chmod 600 ~/.ssh/authorized_keys
chmod 700 ~/.ssh
