아래 편집기에서 MySQL-그룹 복제 구성 단계(권장)에 대한 기사를 볼 수 있습니다. 편집자님이 꽤 좋다고 생각하셔서 지금 공유하고 모두에게 참고용으로 드리고자 합니다. 편집기를 따라 살펴보겠습니다.
MySQL-Group-Replication은 mysql-5.7.17 버전에서 개발된 새로운 기능으로, 마스터-슬레이브 간의 강력한 일관성을 달성합니다.
그러나 지금은 , 주된 이유는 성능이 그다지 좋지 않기 때문입니다.
[1] 현재 mysql 데이터베이스 버전이 5.7.17 이상인지 확인하세요.
/usr/local/mysql/bin/mysqld --version /usr/local/mysql/bin/mysqld Ver 5.7.17 for linux-glibc2.5 on x86_64 (MySQL Community Server (GPL))
[2] 실험 환경은 하나의 호스트에 3개의 mysql을 설치하여 그룹 복제 그룹
/tmp/4406.cnf을 구성한다.
