其中   APPLYING_TRANSACTION: b0610c84-8a92-11ee-be7e-2a26553b6ba7:12  就是我们要跳过的事务

3.跳过事务

复制代码

mysql> set gtid_next='b0610c84-8a92-11ee-be7e-2a26553b6ba7:12';
Query OK, 0 rows affected (0.00 sec)

mysql> begin; commit;    ## 设置空事件，如果不设置，会重启slave时会报错
Query OK, 0 rows affected (0.00 sec)

Query OK, 0 rows affected (0.00 sec)

mysql> set session gtid_next = automatic;  ##重新获取gtid的事件
Query OK, 0 rows affected (0.00 sec)

mysql> start slave;
Query OK, 0 rows affected (0.00 sec)

4.再次查看

复制代码

	mysql> show slave status\G
