mysql开启gtid并配置主从

默认主从都开启了bin log.
1.主从都在/etc/my.cnf中加入并重启服务
gtid_mode = ON
enforce_gtid_consistency = ON
2.在主库创建用户并授权

create user slave identified with mysql_native_password by '123456'
mysql>GRANT REPLICATION SLAVE ON *.* to 'slave'@'%' identified by '123456'; //如果用户已存在，会改密码，如果不存在会直接创建这个用户，所以不需要create user单独创建用户
mysql>FLUSH PRIVILEGES;

2.在从库10.153.35.5中执行
CHANGE MASTER TO
MASTER_HOST='10.153.35.2',
MASTER_USER='slave',
MASTER_PASSWORD='123456',
MASTER_AUTO_POSITION = 1;

3.在从库开启复制线程
mysql> SHOW SLAVE STATUS\G

             Slave_IO_Running: No
            Slave_SQL_Running: No

mysql> START SLAVE IO_THREAD;
Query OK, 0 rows affected (0.01 sec)
mysql> START SLAVE SQL_THREAD;
Query OK, 0 rows affected (0.01 sec)

3.在从库开启复制线程
mysql> SHOW SLAVE STATUS\G

             Slave_IO_Running: Yes
            Slave_SQL_Running: Yes

如果从库报错，需要调过这个报错的事务，怎么处理？

第一种方式使用GTID_NEXT进行单个事务跳跃：
从库：
stop slave sql_thread;
SET @@SESSION.GTID_NEXT= '0f7a8bd3-d7cd-11ef-9ed5-00505695e953:5'; <<===GTID对应第三步查出来的失败事务的GTID
show global variables like '%gtid%'; <<===查看全局GTID信息
begin;commit; <<===执行空事务
SET @@SESSION.GTID_NEXT=automatic;                          <<===GTID自动执行
start slave sql_thread; <<===启动SQL线程
show slave status\G; <<===确认事务已跳过    

mysql> show slave status\G;

2.使用gtid_purged跳过多个事务。
