三、MGR配置
1. mysql_mgr_01
[mysql_mgr_01]
#关闭SQL_LOG_BIN
SET SQL_LOG_BIN=0;
#创建组复制使用的帐号密码
CREATE USER rpl_user@'%' IDENTIFIED BY 'password';
GRANT REPLICATION SLAVE ON *.* TO rpl_user@'%';
FLUSH PRIVILEGES;
#开启SQL_LOG_BIN
SET SQL_LOG_BIN=1;
#安装组复制插件group_replication.so
INSTALL PLUGIN group_replication SONAME 'group_replication.so';
CHANGE MASTER TO MASTER_USER='rpl_user', MASTER_PASSWORD='password' FOR CHANNEL 'group_replication_recovery';
#初始化主节点
SET GLOBAL group_replication_bootstrap_group=ON;
START GROUP_REPLICATION;
SET GLOBAL group_replication_bootstrap_group=OFF;
#查看组复制成员状态
SELECT * FROM performance_schema.replication_group_members;
#备份
mysqldump -uroot -p --all-databases --master-data=2 --single-transaction>/tmp/all.sql
2. mysql_mgr_02
[mysql_mgr_02]
#恢复备份
#安装组复制插件group_replication.so
INSTALL PLUGIN group_replication SONAME 'group_replication.so';
CHANGE MASTER TO MASTER_USER='rpl_user', MASTER_PASSWORD='password' FOR CHANNEL 'group_replication_recovery';
#启动组复制
START GROUP_REPLICATION;
3. mysql_mgr_03
[mysql_mgr_03]
#恢复备份
#安装组复制插件group_replication.so
INSTALL PLUGIN group_replication SONAME 'group_replication.so';
CHANGE MASTER TO MASTER_USER='rpl_user', MASTER_PASSWORD='password' FOR CHANNEL 'group_replication_recovery';
#启动组复制
START GROUP_REPLICATION;
