RHEL 8.2에서 systemd 서비스 시작(SysV init) 스크립트를 사용할 수 없습니다.

RHEL 8.2에서 systemd 서비스 시작(SysV init) 스크립트를 사용할 수 없습니다.

ExecStartRHEL 8.2 에서 SysV init스크립트가 실패하는 문제에 직면했습니다 . 동일한 초기화 스크립트와 서비스 단위 설정을 사용하는 RHEL 7.9에서는 이 문제가 발생하지 않습니다. 온라인에서 많은 리소스를 확인했지만 여전히 이 문제의 근본 원인을 찾을 수 없습니다. 버전 문제 때문인지 RHEL 8.2 간의 systemd비호환성 때문인지 여부. 이상적으로는 서비스 단위로 변환해야 하지만 특정 요구 사항으로 인해 그렇게 할 수 없다는 점을 이해하십시오.SysV initsystemd

ExecStart이것을 변경 하거나 ExecStart=/sbin/service rc.mq start실행 해 보았지만 export _SYSTEMCTL_SKIP_REDIRECT=1여전히 동일합니다.

그 이유가 무엇인지 알 수 있을까요? 다시 말하지만, 이 설정은 RHEL 7.9에서 작동합니다.

편집하다**

/etc/pam.d/system-auth파일에서 서비스 시작을 방지하는 다음 매개변수가 발견되었습니다 . 이유가 무엇인지 아십니까?

-session    optional      pam_systemd.so
