안녕하세요, 인프런 AI 인턴입니다. rjf1138님,

curl -XGET 'localhost/health_check' 명령어 실패와 관련하여 발생하고 있는 문제에 대해 도움을 드리겠습니다. 현재 로그 상에서 여러 가지 타임아웃 에러와 git, JDK 설치 실패가 발생하고 있는 것으로 보입니다. 이 문제들은 주로 네트워크 연결 문제나 서브넷 및 인스턴스의 설정으로 인해 발생할 수 있습니다. 다음의 단계를 따라 확인해 보시길 권장드립니다.

네트워크 구성을 재검토:
- NAT 게이트웨이가 올바르게 설정되어 있어 외부 인터넷에 액세스할 수 있는지 확인합니다.
- 올바른 라우트 테이블이 사용되고 있는지 확인하고, 인스턴스가 위치한 서브넷이 인터넷 게이트웨이 또는 NAT 게이트웨이를 통해 인터넷 접근이 가능한지 검토해 보세요.
보안 그룹 설정 확인:
- 인스턴스가 인터넷에 연결할 수 있도록 아웃바운드 규칙이 0.0.0.0/0으로 열려 있는지 확인합니다.
- 보안 그룹이 외부 트래픽을 허용하도록 설정되었는지도 체크해야 합니다.
리포지토리 접근 설정:
- yum 또는 apt-get 명령이 올바르게 작동하도록 프록시 설정(있는 경우)을 확인하거나, 리포지토리 URL이 차단되어 있는지 확인해야 할 수도 있습니다.
실행 파일 및 디렉토리 확인:
- 실행 중인 스크립트에서 설정된 경로에 필요한 파일들이 있는지 확인합니다. 특히 git, java, 및 스크립트 경로를 한번 더 확인해 주세요.
문서와 유사 사례 참고:
- 유사한 문제로 AWS에서의 연결 문제 해결 문서를 참조하여 문제 해결에 도움을 받을 수 있습니다.
- 아래 링크를 통해 유사한 문제를 겪은 사례를 참고하시면 도움이 될 것입니다:
  - ### 유사 질문: Private EC2 인스턴스 접속에는 성공하였는데
```
   - NAT 게이트웨이 및 라우팅 테이블 설정 확인에 대한 내용이 포함되어 있습니다.
```

위 단계를 확인하신 후에도 문제가 계속될 경우, 스크립트의 내용을 조금 더 자세하게 검토하거나 네트워크 구성에 대한 추가적인 정보를 제공해 주시면 더 깊이 있는 도움을 드릴 수 있습니다.

저는 질문자님의 이해를 돕고자 지식공유자님의 기존 답변을 참고하여 유사한 답변 링크를 추천해드리고 있습니다.
현재 베타 기능으로 답변이 만족스럽지 않을 수 있는 점 양해 부탁드립니다. 🙏
추가적으로 궁금한 점이 있으시면, 이어서 질문해 주세요. 곧 지식공유자께서 답변해 주실 것입니다.
