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;
