集群开始还好好的，今天不知道为什么，突然不行了
本来以为重启网卡就好了，没想到重启网卡也报错了，在网上找了些方法，网卡配置也没错，如下：
TYPE -Ethernet
BOOTPROTO=dhcp
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPU4 FAILURE FATAL =no
IPU6 IN IT=yes
IPU6 AUTDCONF=yes
IPU6_ DEFROUTE=yes
IPU6_ PEERDNS=yes
IPU6_ PEERROUTES=yes
IPU6_ FA ILURE FATAL=nO
NAME=eno16777736
UUID=08c4f de5 -ff 4a -48c9 -8d6a -de64bZd46763
DEUICE=eno16777736
IPADDR=192.168.126.137
#NETWASK-255.255.255.0
#GATEWAY=192.168.126.1
ONBOOT=yes
我又输入了 ip addr 结果如下：
"ifcf g -eno16777736" 19L，358C Lur itten
[rootQhadoop2 network -scripts]# ip addr
