可以看到gtid_set下面有数了，这说明已经开启了gtid模式
Part3:GTID变更为传统模式
mysql> stop slave;-----从库执行
Query OK, 0 rows affected (0.00 sec)
mysql> set global gtid_mode='ON_PERMISSIVE';
Query OK, 0 rows affected (0.00 sec)
mysql> set global gtid_mode='OFF_PERMISSIVE';

mysql> set global gtid_mode='OFF';
Query OK, 0 rows affected (0.00 sec)
mysql> start slave;

mysql> show variables like '%gtid%';

可以看到这里GTID模式已经关了，下面再次开启GTID模式来观察id的变化
