Last_SQL_Errno: 0 Last_SQL_Error:1 row in set (0.00 sec)(1) master and slave have equal MySQL server ids
【解决办法】
修改/etc/my.cnf 下的server-id的值，确保master和slave的server-id不一样即可；
(2) Error reading packet from server:
Access denied; you need the REPLICATION SLAVE privilege for this operation ( server_errno=1227)
【解决办法】主服务器给的复制权限不够，重新赋予权限。
