다음과 같이 MariaDB Galera 클러스터를 설정하려고 합니다.이것튜토리얼이 똑같아서 계속 멈췄어요7단계 – 첫 번째 클러스터 노드 초기화, 저는 이 일을 하고 sudo /etc/init.d/mysql start --wsrep-new-cluster있는데 얼마 후에는 다음 Starting MySQL.....과 같이 끝납니다.Starting MySQL..... ERROR!
무슨 일인지 말해 줄 사람 있나요? 이것은 내 MySQL 로그입니다.

답변1
해결되었습니다. 문제는 SELinux에 있었습니다. 명시적으로 허용 모드로 설정했지만 변경 사항을 올바르게 적용하기 위해 재부팅하지 않았습니다. 그래서 SELinux의 현재 상태를 확인해 sestatus보니 Permissive 모드로 구성되어 있지만 Enforcing 모드로 실행되고 있는 것으로 나타났습니다.
