I’ moving my discourse to a new vps, using Move a Discourse site to another VPS with rsync - Documentation / Self-Hosting - Discourse Meta
After copying full files, launching /discourse-setup I got this error:
570:M 27 Jul 2024 14:26:52.569 # Warning: Could not create server TCP listening socket *:6379: bind: Address already in use
570:M 27 Jul 2024 14:26:52.569 # Failed listening on port 6379 (TCP), aborting.
Postgresql 문제인 것 같습니다
다음과 같은 오류를 발견했습니다
PG::ConnectionBad: 소켓 "/var/run/postgresql/.s.PGSQL.5432"에 대한 서버 연결 실패: 파일 또는 디렉터리가 없습니다 (PG::ConnectionBad)

./discourse-doctor가 문제를 진단하는 데 도움이 될 수 있습니다.
다시 시도해 보았습니다. 동일한 오류가 발생합니다.
제안이 있을까요?
Ubuntu 18.04에서 Ubuntu 24.04로 이관했습니다.
PostgreSQL 사용자 설정에서 문제를 찾았습니다.
빈 데이터베이스로 설치를 시도한 후, 사이트 설정이 완료되면 데이터를 복원하는 방법을 추천합니다.
현재 사용 중인 버전과 새 서버의 버전 사이에 경미한 버전 차이가 있어 문제가 발생하는 것 같습니다. 다른 가능성으로는, 파일을 복사하기 전에 기존 서버를 완전히 종료하지 않은 경우를 들 수 있습니다.
./launcher stop app을 사용했습니다.
이제 다른 도메인으로 새로 설치했습니다.
내일 도메인 변경 후 재빌드, app.yml 수정 후 재빌드, 그리고 복구를 시도해 볼 예정입니다.
어제 저도 정확히 같은 오류가 발생했어요 
내일 새로 설치하고 복원할 예정입니다
새 도메인 이름으로全新 설치(Fresh install)를 수행했습니다.
호스트명을 변경하되 재빌드(rebuild)하지 않고, letsencrypt 디렉토리를 새 서버로 복사했습니다. 그런 다음 DNS를 변경하고 복원을 수행했습니다. 모든 것이 정상적으로 작동했습니다.
rsync 관련 주제로 혼란을 겪고 있습니다. 다른 VPS에 도메인 이름이 다른 제 셀프호스트된 Discourse 사이트의 두 번째 인스턴스를 만들고 싶습니다. 단순히 새로운 Discourse 사이트를 생성하고, 두 사이트 모두 최신 버전으로 업데이트한 후, 원본 사이트에서 백업을 만들어 새 VPS에 복원하는 방식으로 하면 안 될까요? 그렇게 할 수 있다면, 그 외 어떤 단계를 따르는 것이 가장 좋을까요? 감사합니다.
백업을 복원하는 것이 원시 데이터베이스 파일을 복사하는 것보다 쉽습니다. 또한, 복원을 수행하면 호스트 이름이 자동으로 변경됩니다.
내부에서는 데이터 및 데이터베이스 파일을 이동하기 위해 수백 시간 분량의 도구를 작성해 두었습니다.
하지만 여전히 백업 파일을 복원하는 것이 더 쉬운 경우가 있습니다.
또한, 백업에서 복원한다고 했을 때, 이는 Discourse GUI의 Advanced → Backup에서 생성된 백업을 의미합니다. 이를 사용하면 기본적으로 사이트를 하나의 VPS에서 다른 VPS로 복제할 수 있어야 하는데, 맞나요? 다른 주제에서는 rsync를 통해 이를 수행하는 경우가 있었는데, 제 생각에는 그렇게 할 필요가 없어 보입니다.
왜 그러시나요? 테스트를 위한 스테이징 사이트를 원하시나요?
그렇다면 가장 쉬운 방법은 새 사이트를 설정한 후, 두 사이트가 백업을 위해 S3 호환 버킷을 공유하도록 구성하고 다른 사이트에서 해당 백업을 복원하는 것입니다.
원하신다면 그렇게 하셔도 됩니다. 하지만 호스트명을 변경하는 데에는 여러 단계가 필요하며, 백업을 복원하는 것이 훨씬 쉽습니다. rsync 방식은 (일부 측면에서) 더 적은 데이터를 이동시키고 최신 OS로 이전할 수 있게 해줍니다(당연히 그렇게 할 필요가 없을 것입니다).
그러니, 네, 그렇게 할 수 있습니다(이미지가 생성될 때 호스트가 종료되어 있었다면). 그런 다음 app.yml에서 호스트명을 편집하고 다시 빌드하면 됩니다. 그래도 가장 최근 백업을 복원하는 것이 더 쉽지만, 원하시는 경우 다음 단계를 따르실 수 있습니다: Change the domain name or rename your Discourse
실제로는 기존 VPS에서 벗어나 새 VPS 제공업체에서 사이트를 작동시켜야 합니다. 현재 VPS는 Ubuntu 22.04이고, 새 VPS는 Ubuntu 24.04입니다. 새 VPS에 표준 Discourse 설치를 수행한 후, 기존 VPS와 새 VPS가 동일한 Discourse 버전을 사용하도록 확인하고, 기존 VPS에서 Discourse GUI 백업을 생성한 뒤 새 VPS에 복원하는 것이 가장 간단한 방법일까요? 이렇게 하면 될까요? 감사합니다.
그래서 OS 전체를 클론하는 대신 rsync를 사용하는 거군요.
왜 다른 호스트 이름을 원하시나요? 하지만 만약 그렇게 하신다면, 깨끗한 설치 후 백업을 복원하시면 됩니다. 그것이 가장 간단한 방법입니다.
기존 서버를 폐기하고 새 서버를 기존 도메인 이름으로 리셋하기 전에, 모든 것이 정상적으로 작동하는지 확인하기 위해 처음에는 다른 호스트네임/도메인 이름을 사용하려고 합니다. 제가 이해한 대로라면, 새 서버에 Ubuntu 24.04를 클린 설치하고 표준 절차에 따라 Discourse를 수동으로 설치한 후, 두 서버의 Discourse 버전이 동일하도록 맞춘 다음, 기존 서버에서 Discourse GUI 백업을 만든 뒤 새 서버에 복원하면 된다는 뜻인가요? 아무 문제 없이 잘 될 것 같네요?
네. 아마도 그렇게 하시는 것이 좋을 것 같습니다.
rsync를 사용하면서 현명하게 처리하면, 새 서버에서 기존 서버의 인증서를 그대로 사용하고 로컬 DNS를 새 서버로 변경하여 정상적으로 작동하는지 확인할 수 있습니다. 이렇게 하면 서버를 전환할 때 다운타임이 전혀 없습니다. 반면, 질문자님의 방식으로는 최종 전환 시 기존 호스트네임으로 새 서버를 재구성하는 동안 다운타임이 발생합니다. 저는 이런 작업을 한 달에 여러 번 수행합니다. . . .
