授权复制用户：

slave1> GRANT REPLICATION SLAVE ON *.* TO repluser@10.10.10.63 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)

测试test库

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
