L'éditeur ci-dessous vous proposera un article MySQL-étapes de configuration de la réplication de groupe (recommandé). L'éditeur le trouve plutôt bon, je vais donc le partager avec vous maintenant et le donner comme référence pour tout le monde. Suivons l'éditeur pour y jeter un œil
MySQL-Group-Replication est une nouvelle fonctionnalité développée dans la version mysql-5.7.17 ; elle permet d'obtenir une forte cohérence entre maître-esclave,
Mais pour l'instant , la raison principale est que les performances ne sont pas très bonnes.
【1】Assurez-vous que la version actuelle de la base de données MySQL est 5.7.17 et supérieure
/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 】L'environnement expérimental consiste à installer trois mysql sur un hôte. Les trois forment un groupe de réplication de groupe

【3】Initialisez trois instances de base de données
cd /usr/local/mysql/ ./bin/mysqld --defautls-file=/tmp/4406.cnf --datadir=/tmp/4406 --initialize-insecrue ./bin/mysqld --defautls-file=/tmp/5506.cnf --datadir=/tmp/5506 --initialize-insecrue ./bin/mysqld --defautls-file=/tmp/6606.cnf --datadir=/tmp/6606 --initialize-insecrue
【4】Configurez l'instance initiale de réplication de groupe
/usr/local/mysql/bin/mysqld --defaults-file=/tmp/4406.cnf &
mysql -h127.0.0.1 -uroot -P4406 -- 增加用户 set sql_log_bin=0; create user rpl_user@'%' identified by '123456'; grant replication slave,replication client on *.* to rpl_user@'%'; create user rpl_user@'127.0.0.1' identified by '123456'; grant replication slave,replication client on *.* to rpl_user@'127.0.0.1'; create user rpl_user@'localhost' identified by '123456'; grant replication slave,replication client on *.* to rpl_user@'localhost'; set sql_log_bin=1; -- 增加复制凭证 change master to master_user='rpl_user', master_password='123456' for channel 'group_replication_recovery'; -- 安装组复制物件 install plugin group_replication soname 'group_replication.so'; -- 启动组复制 set global group_replication_bootstrap_group=on; start group_replication; set global group_replication_bootstrap_group=off;
【5】Le processus de configuration de l'instance 5506 est le suivant :
/usr/local/mysql/bin/mysqld --defaults-file=/tmp/5506.cnf &
mysql -h127.0.0.1 -uroot -P5506 -- 增加用户 set sql_log_bin=0; create user rpl_user@'%' identified by '123456'; grant replication slave,replication client on *.* to rpl_user@'%'; create user rpl_user@'127.0.0.1' identified by '123456'; grant replication slave,replication client on *.* to rpl_user@'127.0.0.1'; create user rpl_user@'localhost' identified by '123456'; grant replication slave,replication client on *.* to rpl_user@'localhost'; set sql_log_bin=1; -- 增加复制凭证 change master to master_user='rpl_user', master_password='123456' for channel 'group_replication_recovery'; -- 安装组复制物件 install plugin group_replication soname 'group_replication.so'; -- 启动组复制 start group_replication; # 注意这里不是初始化了,只要加入就行
【6】Le fonctionnement de l'instance 6606 est le même que celui de l'instance 5506. Le fonctionnement est le même et la configuration de la réplication de groupe est terminée.
