解决办法:
mysql> change master to master_log_file='mysql-bin.000001',master_log_pos=315;
Query OK, 0 rows affected (0.01 sec)

报错:
Fatal error: The slave I/O thread stops because master and slave have equal MySQL server UUIDs; these UUIDs must be different for replication to work. 
解决办法:
Mysql/data目录,把auto.cnf文件也拷贝过来了,里面记录了数据库的uuid,每个库的uuid应该是不一样的。
[auto]
server-uuid=39a19e0a-7957-11e6-aa19-0800272020f5
