mysql 复制失败，GTID 且无法恢复

Question

我已经配置了 MySQL 复制并且工作正常。我不小心删除/修改了从属设备上的一些用户，并在主设备上执行了相同的操作。之后复制停止并在“显示从属状态\G”上给出以下错误

我尝试设置SET GLOBAL SQL_SLAVE_SKIP_COUNTER = 1，它给出了以下消息，

mysql> SET GLOBAL SQL_SLAVE_SKIP_COUNTER = 1;
ERROR 1858 (HY000): sql_slave_skip_counter can not be set when the server is running with @@GLOBAL.GTID_MODE = ON. Instead, for each transaction that you want to skip, generate an empty transaction with the same GTID as the transaction

我也尝试了以下操作，但也没有帮助，

mysql> STOP SLAVE;
Query OK, 0 rows affected (0.00 sec)

mysql> SET GTID_NEXT="aaa2545a-4437-11e7-9f03-0021f6f0406f:20"
    -> ;
Query OK, 0 rows affected (0.00 sec)

mysql> BEGIN; COMMIT;
Query OK, 0 rows affected (0.00 sec)

Query OK, 0 rows affected (0.00 sec)

mysql> SET GTID_NEXT="acc29e29-4437-11e7-8074-0021f6f0406e:23";
Query OK, 0 rows affected (0.01 sec)

mysql> BEGIN; COMMIT;
Query OK, 0 rows affected (0.00 sec)

Query OK, 0 rows affected (0.00 sec)

mysql> SET GTID_NEXT="aaa2545a-4437-11e7-9f03-0021f6f0406f:31";
Query OK, 0 rows affected (0.00 sec)

mysql> BEGIN; COMMIT;
Query OK, 0 rows affected (0.00 sec)

Query OK, 0 rows affected (0.00 sec)

mysql> SET GTID_NEXT="AUTOMATIC";
Query OK, 0 rows affected (0.01 sec)

mysql> START SLAVE;
Query OK, 0 rows affected (0.00 sec)

有什么方法可以恢复这个并使复制正确进行。

我已经在Slave节点上重新安装了MySQL并重新配置了它。
