하트비트 3 바인드 소켓 오류

저는 항상 yum을 통해 CentOS 6.3 64비트에 Heartbeat3.0.5+Pacemaker1.0.12를 설치하고 싶었습니다. 설치는 성공한 것 같은데 하트비트 실행시 문제가 발생합니다.

이 문제와 관련된 몇 가지 정보를 아래에 나열했습니다.

답변1

어쨌든 한번 시도해 보시고 제공하신 정보에 따르면 SELinux 정책 문제가 있는 것으로 보입니다.

SELinux가 활성화되어 있는지 확인하는 방법은 무엇입니까?

[root@ragnarok ~]# getenforce  
Enforcing

명령이 강제 실행을 반환하면 시스템이 SELinux가 활성화된 상태로 실행되고 있는 것입니다. 이 경우 허용 모드로 전환하여 문제가 해결되는지 살펴보겠습니다.

SELinux 모드를 허용 모드로 변경하는 방법은 무엇입니까?

[root@ragnarok ~]# setenforce 0
[root@ragnarok ~]# getenforce 
Permissive

이는 재부팅할 때까지 작동하므로 이제 실패한 서비스를 시작해 볼 차례입니다.

운이 좋게 성공하면 다음과 같은 버그/정오표가 발생할 수 있습니다.

https://bugzilla.redhat.com/show_bug.cgi?id=809746

버그 리포터가 제공하는 명령을 확인하여 결과가 동일한지 확인할 수 있습니다. 이 경우 문제는 6월 이후 업스트림에서 수정된 것으로 보이며 시스템을 업데이트하거나 CentOS가 수정 사항을 적용할 때까지 기다려야 할 수도 있습니다.

조사 결과에 대한 피드백을 보내주세요.
