一、异常表现
[root@master zkpk]# ping slave
PING slave (192.168.82.94) 56(84) bytes of data.
From master (192.168.82.9) icmp_seq=2 Destination Host Unreachable
From master (192.168.82.9) icmp_seq=3 Destination Host Unreachable
From master (192.168.82.9) icmp_seq=4 Destination Host Unreachable
二、异常分析
1.查看其是否都在同一网段
2.若用别名，要查看/etc/hosts书写是否有误
3.查看防火墙是否关闭
4.查看二者是否在同一模式，如图：
5.查看他们是wired networks是否相同
如图：master 、salve 、slave1三者的wired networks
master:
slave:
slave1:
