解决方法：将/etc/hosts文件中的内容添加如下所示

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.10.10 master.303kfy.net master localhost.localdomain

192.168.10.51 slave1.303kfy.net slave1 localhost.localdomain

192.168.10.52 slave2.303kfy.net slave2 localhost.localdomain

192.168.10.53 slave3.303kfy.net slave3 localhost.localdomain

192.168.10.54 slave4.303kfy.net slave4 localhost.localdomain

192.168.10.55 slave5.303kfy.net slave5 localhost.localdomain

192.168.10.56 slave6.303kfy.net slave6 localhost.localdomain

必须在你要使用这个命令的机器上有相应的IP和域名在这个/etc/hosts文件中。
