<blockquote>네 맞습니다.하나의 인스턴스에서 유저 데이터 스크립트가 초기에 함번 실행되고, 중단하고 다시 시작할땐 스크립트기 실행되지 않습니다. 현재 구조로 답변 드리면 계속 접속해서 실행시켜줘야하는게 맞습니다. 하지만 이후 강의에서 배우게 되는 시작템플릿과 오토스케일링 그룹을 도입하게 되면 이런 부분은 간단하게 해결되니 이후 강의도 수강해주시면 도움 되실거에요!</blockquote>넵 이해했습니다! 덕분에 찝찝했던 부분 없이 속 시원하게 해결되었습니다! 감사합니다!!

goopang-target-group 에서 unhealthy

안녕하세요 강사님. 답변해주신 내용 확인했습니다! 그렇다면, 초기에 private-ec2-instance 를 처음 실행할 때가 아닌, Stop Instance 로 중단했다가, Start Instance 로 인스턴스를 재시작하는 경우에는 User Data 의 스크립트가 실행되지 않는다는 말씀이시죠? 그렇다면 인스턴스 실행을 중단(Stop Instance)을 했다가 재실행(Start Instance)할 때 마다 User Data 의 스크립트를 실행하는 방법은 없을까요? 매번 private-ec2-instance 에 접속해서 직접 스크립트를 실행해서 테스트를 진행해야 할까요?

안녕하세요 강사님. 빠른 답변 항상 감사드립니다. 말씀해주신 스크립트 내용을 private-ec2-instacne 의 User Data 내용으로 변경 후에는 역시나 Health checks failed 하였으나, private-ec2-instance 에 EC2 Instance Connect Endpoint 를 이용하여 직접 접속한 후에 aws-operation-prac 으로 폴더 이동 후에 아래 명령어를 직접 실행했을 때는 health check 성공한 것으로 확인됩니다. <code>./gradlew build sudo java -jar build/libs/aws-msa-monolithic-prac-0.1.jar</code>&nbsp;뭔가 ec2 인스턴스에서 sudo java -jar 로 애플리케이션 실행 후에 뭔가 문제가 있는 걸까요? private-ec2-instance 에 직접 접속 후에 <code>ls-al</code> 명령어로 파일 확인 시에 aws-operation-prac 프로젝트도 정상적으로 git clone 되어 있는 것 확인했습니다. &nbsp;

<blockquote>우선 target group의 health check settings에 interval 시간이나 Unhealthy threshold 수를 늘려보면 좋을것같습니다.interval - 30초 이상Unhealthy threshold - 4회 이상이렇게 넉넉하게 설정해서 테스트하고, 테스트 한번 부탁드릴게요!</blockquote>넵 답변 감사합니다 강사님. 말씀해주신 것 처럼 <code>Unhealthy threshold - 5회, interval - 30초</code> | <code>Unhealthy threshold - 7회, interval - 60초 </code> 로 설정해보았는데, 2번 다 여전히 <code>health checks failed </code> 로 확인됩니다.. 추가적으로 확인해볼 부분이 있을까요..?&nbsp;<img src="https://cdn.inflearn.com/public/files/posts/a2a9112a-4650-441e-8474-fa17cd242948/212cec66-4c53-4662-9d2f-c686a972de0c.png" media-type="img" alt="스크린샷 2024-10-31 오후 6.51.13.png" title="스크린샷 2024-10-31 오후 6.51.13.png" width="396" height="195">&nbsp;<img src="https://cdn.inflearn.com/public/files/posts/60c86648-8474-4413-b3ce-5b81c12d67f5/537ca5e4-1b48-4478-b26f-2663747ab531.png" media-type="img" alt="스크린샷 2024-10-31 오후 6.51.50.png" title="스크린샷 2024-10-31 오후 6.51.50.png" width="396" height="74">&nbsp;

안녕하세요 강사님. 빠른 답변 항상 감사드립니다.&nbsp;<blockquote>지금으로 의심되는 부분은 보안그룹 설정 정도 될것같습니다. alb에서 ec2 인스턴스로 가는 트래픽에 대한 보안그룹 설정 한번 확인 부탁드릴게요! 정상적으로 설정되어있다면, 인스턴스가 생성되고, 애플리케이션이 실행된 상태에서 인스턴스에 접속하여 curl로 health_check 요청이 정상적으로 되는지 그리고 target group에 설정된 health check 설정도 확인해보면 좋을것같습니다!</blockquote>&nbsp;말씀해주신 부분들 전부 확인해보았는데, 문제가 없어 보여서 다시 질문 드립니다.. 우선, <code>goopang-alb-sg</code> 의 inbound-rules 에서 http 요청 받을 수 있도록 설정 되어 있고, <code>goopang-private-ec2-sg</code> 의 inbound-rules 에는 alb 와 bastion-host sg 들 요청 받을 수 있도록 설정되어 있는 것 확인했습니다.&nbsp;<code>target-group</code> 의 <code>Health check settings</code> 도 아래 이미지와 같이 <code>/health_check</code> 경로 설정 등 강의 설명과 같이 설정되어 있는 것 확인했습니다. <code>bastion-host</code> 인스턴스를 이용하여 private-ec2-instance 접속 후에 <code>curl -XGET 'localhost/health_check'</code> 로 요청 정상 작동 확인 시에는 아래의 코드 블럭 내용과 같이 server 에 접속 실패하였다고 나옵니다. <code>private-ec2-instance</code>에 EC2 Instance Connect Endpoint 를 이용하여 직접 접속 후 같은 요청을 보내보아도 아래 코드 블럭과 같은 에러(<code>Failed to connect to localhost port 80 after 0 ms: Couldn't connect to server</code>)가 반환됩니다..&nbsp;<code>private-routing-table</code> 에도 <code>nat-instance</code> 설정되어 있는 것 확인했습니다.&nbsp;<code>User Data</code> 스크립트 log 확인(cat /var/log/cloud-init-output.log)은 이전 답글에 보낸 것과 같이 <code>AwsMsaMonolithicPracApplicationKt</code> 서버가 제대로 떴다가 다시 shutdown 되는 것으로 보입니다..&nbsp;혹시 제가 추가적으로 확인해볼만한 것이 있을까요..?

안녕하세요 강사님. private-ec2-instance 를 며칠동안 stop 시켜놨다가 다시 run 시켰더니 또 target-group 에서 Unhealthy 라고 떴습니다. 그래서 이번엔 privaet-ec2-instance 에 EC2 Instance Connect Endpoint 를 이용하여 직접 접속한 후, cat /var/log/cloud-init-output.log 명령어를 통해 log 를 확인하였더니, 서버가 잘 떴다가 아래의 에러가 발생합니다.

안녕하세요 강사님. 말씀해주신 2가지 방법 다 적용해보았습니다. 1번. Private ec2 에 접속해서 스크립트 명령어를 직접 입력 -> EC2 Instance Connect Endpoint 를 이용해서 인스턴스에 접속했고, 명령어가 모두 정상적으로 실행되었습니다. 심지어 <code>sudo java -jar build/libs/aws-msa-monolithic-prac-0.1.jar </code>private ec2 에 접속한 상태에서 해당 명령어로 서버를 실행했을 때 alb 의 target group 이 <code>healthy</code> 상태로 표시됩니다. 2번. Nat instance 대신 Nat gateway를 사용해보기 -> 이건 여전히 문제가 발생했었습니다. 이 2가지 결과를 보았을 때, Private ec2 instance 를 run 할 때, User Data 의 스크립트에 문제가 있는 것으로 보고 혹시나 하는 마음에 모든 스크립트 내용을 개행 시켜줬습니다. 그렇게 해서 문제 해결했습니다!! 백엔드 개발자지만 직접 이렇게 만져본 경험은 많지 않아서 많이 헤맸는데 강사님의 빠른 답변으로 속 시원하게 문제 해결했습니다. 감사합니다!

안녕하세요 강사님. 매번 빠른 답변 정말 감사합니다. 넵 그래서 확인해봤는데, goopang-nat-instance 가 goopang-private-routing-table 에 route 로 설정이 제대로 되어있고, ping-test-instance 로 외부로 트래픽이 잘 나가는지 테스트도 해보았는데, ping 테스트도 정상적으로 작동합니다.. 그래도 여전히 문제가 발생하네요.. (참고로 route table 의 Target 에 있는 eni-xxxx 는 Instance 설정 후 goopang-nat-instance 로 선택 후 저장하니까 네트워크 인터페이스로 자동 설정되었습니다.)<img src="https://cdn.inflearn.com/public/files/posts/757604c4-5ef9-436a-963b-a07c7f1cc946/9c558838-11af-46a2-b028-f87e1d4f35f2.png" media-type="img" alt="스크린샷 2024-10-24 오후 5.21.43.png" title="스크린샷 2024-10-24 오후 5.21.43.png" width="352" height="220">&nbsp;<img src="https://cdn.inflearn.com/public/files/posts/722d0265-3c2a-4e5e-a5c7-0c788823cbe9/e62ef082-0c0b-4a1d-912a-f0f73712393a.png" media-type="img" alt="스크린샷 2024-10-24 오후 5.14.34.png" title="스크린샷 2024-10-24 오후 5.14.34.png" width="352" height="319">&nbsp; 혹시나 vpc, subnet, route tables 설정 때 부터 잘못되었나 싶어서 앞의 강의들도 재시청했는데, 설정은 강사님이 하신데로 제대로 되어있었습니다.. 그래도 혹시 추가로 체크해야할 부분이 있을까요?

안녕하세요 강사님. 늦은 밤에 빠른 답변 정말 감사합니다. 그런데 private-ec2-instance, NAT-Instance 를 둘 다 t4g.small 에서 t4g.medium 으로 instance type 을 변경했는데도 여전히 <code>unhealthy</code> 로 확인됩니다.. 현재 bastion-host-instance 에 접속해서 private-ec2-instance 로 pem키를 이용한 ssh 접속은 정상적으로 진행되나 섹션 5 Private EC2 Instance 접속(실습) 에서와 같이 <code>curl -XGET</code> 으로 health_check 요청은<code>curl: (7) Failed to connect to localhost port 80 after 0 ms: Couldn't connect to server</code> 와 같이 실패합니다. <code>cat /var/log/cloud-init-output.log</code> 명령어로 log 를 확인해봤을 때 아래와 같은 에러가 발생합니다. git, JDK, git clone 이 모두 실패하는 것으로 보이는데 원인을 잘 모르겠습니다.. User Data 에 스크립트는 정확하게 들어있는 것 확인했습니다. <pre><code>Cloud-init v. 22.2.2 running 'modules:config' at Tue, 22 Oct 2024 14:53:05 +0000. Up 7.18 seconds.
