[root@linux-node2~]# cd /etc/sysconfig/network-scripts/#進入網卡目錄
[root@linux-node2network-scripts]# mv ifcfg-eno16777728 ifcfg-eth0#重命名網卡名稱
[root@linux-node2network-scripts]# cat ifcfg-eth0 #編輯網卡信息
TYPE=Ethernet
BOOTPROTO=static
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
NAME=eth0#name修改為eth0
ONBOOT=yes
