一、硬件
1.为虚拟机添加网卡
2.配置网卡
二、软件
3.获取mac地址
命令：ip link
[root@vbox network-scripts]# ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp0s3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000link/ether 08:00:27:9a:97:5e brd ff:ff:ff:ff:ff:ff
3: enp0s8: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000link/ether 08:00:27:19:ba:4d brd ff:ff:ff:ff:ff:ff
4.获取UUID
命令：nmcli con
[root@vbox network-scripts]# nmcli con
NAME UUID TYPE DEVICE
enp0s3 40193217-26b5-4246-94f8-13449410d506 ethernet enp0s3
enp0s8 fa9dd332-b1ff-3f86-ab1e-fa7c028d20b6 ethernet enp0s8
5.修改配置文件
命令：cd /etc/sysconfig/network-scripts/ifcfg-enp0s3
命令：cp ifcfg-enp0s3 ifcfg-enp0s8

6.重启网卡
命令：systemctl restart network
