Rsyslog는 /var/log/messages 및 하위 폴더에 계속 기록합니다.

Question

이 구성 부분을 사용하여 여러 시스템을 하위 폴더로 구성한 CentOS 8에 rsyslog가 있습니다.

$template RemoteLogs,"/var/log/hosts/%HOSTNAME%/%$YEAR%/%$MONTH%/%$DAY%/syslog.log"
*.* ?RemoteLogs

이것은 잘 작동하지만 원격 시스템의 모든 로그는 /var/log/messages에 기록됩니다. 자체 하위 폴더에 원격 로그가 있고 기록되지 않는 방법은 무엇입니까?/var/log/메시지?

여기 내 구성 파일이 있습니다.

Answer 1

중지를 사용하지 않고 외부 로그를 저장하도록 사양을 정의하고 있습니다. 따라서 외부 로그는 템플릿과 로컬 syslog에도 저장됩니다. 외부 로그에만 템플릿을 사용하려면 다음을 사용합니다.

*.* ?RemoteLogs
if $fromhost-ip != '127.0.0.1' then  stop

그러면 외부 로그가 템플릿에 저장되고 IP가 127.0.0.1이 아니므로 프로세스가 중지됩니다. 이는 로컬 로그도 RemoteLogs 템플릿에 기록된다는 의미입니다. 물론 정지선의 위치는 템플릿 사용 직후여야 합니다!
