创建授权用户(master)

mysql> create user haha@'192.168.118.112' identified by '123456';
Query OK, 0 rows affected (0.00 sec)

mysql> grant replication slave on *.* to 'haha'@'192.168.118.112';
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

配置基于gtid的复制(从)

mysql> change master to
    master_host='192.168.118.222',
    master_user='haha',
    master_password='123456',
    master_port=3306,
    master_auto_position=1;
Query OK, 0 rows affected, 2 warnings (0.01 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql> show slave status\G
