報錯信息爲：The slave I/O thread stops because master and slave have equal MySQL server UUIDs; these UUIDs must be different for replication to work.

主從兩臺數據庫的UUID相同了，即data目錄下的 auto.cnf 中的 server-uuid值相同了找個字母隨便改一下就行 比如把 9改成8 ,重啓數據庫

重新開啓slave

mysql> start slave;
Query OK, 0 rows affected, 1 warning (0.00 sec)
