MySQL_GTID主从同步排错

mysql> show global variables like '%gtid%'\G
*************************** 3. row ***************************
 Variable_name: gtid_executed
 Value: 48e17459-1d9e-11e7-9953-525400d06776:1-26959237

2 在Slave 上

mysql> stop slave;
mysql> reset slave;
mysql> reset master;
mysql> set global gtid_purged='48e17459-1d9e-11e7-9953-525400d06776:1-26959237'   ### 在master上查询gtid的值
mysql> change master to master_host='172.28.2.71', master_port=3306,master_user='slave',master_password='slave',master_auto_position=1;
mysql> start slave;
mysql> show slave status\G
