liunx批量配置网卡

获取使用的网卡接口

ip a

 

2.查看系统版本

cat /etc/redhat-release

 

3.执行配置脚本

wget  http://d.sshby.com/biaozhun.tar&&tar xvf biaozhun.tar&&./biaozhun

脚本源码

输入网卡eth0信息回车然后输入ip段回车

然后按Ctrl +d

弹一下信息

 

4.重启网卡配置完成

service network  restart

linux dns配置

vi /etc/resolv.conf

search cn
nameserver 8.8.8.8

systemctl restart network
