注意：
mysql02也要配置binlog，不然，mysql03上會報：
2017-10-25 19:21:20 2352 [ERROR] Error reading packet from server: Binary log is not open (server_errno=1236)
2017-10-25 19:21:20 2352 [ERROR] Slave I/O: Got fatal error 1236 from master when reading data from binary log: 'Binary log is not open', Error_code: 1236
