내 systemctl 로그에 이 내용이 표시됩니다. systemd-journal-flush.service가 시간 초과 오류로 인해 시작되지 않습니다. 하지만 서버는 잘 돌아가고 있는 것 같습니다. 운영체제는 CentOS 8입니다. 로그에는 오류가 자세히 설명되어 있지 않습니다. 누구든지 나를 도울 수 있다면 감사하겠습니다.

디렉터리가 존재하지 않기 때문에 데몬이 journald새로 고쳐지지 않으며 디렉터리를 생성하라는 메시지도 표시되지 않습니다. 불행하게도 새로 고침이 완료되기를 기다리다가 완료되지 않습니다./var/log/journal/etc/systemd/journald.confjournalctl --flush
나에게 도움이 된 해결책은 다음과 같습니다.
sudoedit /etc/systemd/journald.conf- 이 줄
[Journal]뒤에 줄을 추가합니다 .Storage=persistent - 재시작.
매뉴얼 페이지를 읽으면 기본값과 어떻게 다른지에 대한 설명을 볼 수 있습니다 journald.conf(5).persistentauto
"auto"는 "영구"와 비슷하지만
/var/log/journal필요한 경우 디렉토리가 생성되지 않으므로 해당 존재가 로그 데이터가 이동하는 위치를 제어합니다.
구성을 변경하고 재부팅하면 journald올바른 권한(분명히 소유자=루트, 그룹=systemd-journal, 모드=02755, ACL은 r-x그룹 adm 및 그룹 휠에 대한 명시적 액세스 권한 부여)을 사용하여 누락된 디렉터리를 생성할 수 있습니다. 물론 다시 시작하지 않고도 직접 만들 수 있습니다.
