授权复制用户：
slave1> GRANT REPLICATION SLAVE ON *.* TO [email protected] IDENTIFIED BY 'redhat'; slave1> flush privileges;
导入数据
[root@slave2 ~]# mysql shop<shop.sql
连接主服务器
salve2> CHANGE MASTER TO MASTER_HOST='slave1.sanyu.com', MASTER_USER='repluser', MASTER_PASSWORD='redhat', MASTER_AUTO_POSITION=1;
开始复制
salve2> start slave; slave1> create table t1(id int); Query OK, 0 rows affected (0.31 sec)

插入一条记录
master> insert into shop.ecs_users(user_name,last_time) values ('slave1',now());
Query OK, 1 row affected, 7 warnings (10.14 sec)
一条简单的记录花了10s+，是启用半同步复制的结果
slave1> select user_id,user_name,last_time from shop.ecs_users;
+---------+-----------+---------------------+
| user_id | user_name | last_time |

可见，一旦启用了基于GTID的复制，所有结点都应该启用
