mysql复制使用gtid，用gtid_purged跳过事务

2019独角兽企业重金招聘Python工程师标准>>>

show slave status查看slave状态时，SQL线程停止运行，错误显示Update错误，如果没有使用gtid，可以使用sql_slave_skip_counter跳过，但是开启gtid后，使用该方式是无效的。

解决办法:

使用
gtid_purged跳过事务，从上面slave状态信息可知，slave当前执行到了
7bdd3156-ff10-11e3-91dc-001018a0b030:1-107805，使用gtid_purged跳过下一个事务
7bdd3156-ff10-11e3-91dc-001018a0b030:1-107806

root@[(none)] 05:36:29> stop slave;
Query OK, 0 rows affected (0.05 sec)
root@[(none)] 05:36:35> reset master;

root@[(none)] 05:36:38> set global gtid_purged='7bdd3156-ff10-11e3-91dc-001018a0b030:1-107806'; #跳过事务
