Virtual Box设置桥接模式

一、硬件

1.查看宿主机ip

cmd命令：ipconfig

无线局域网适配器 WLAN:

   连接特定的 DNS 后缀 . . . . . . . :
   IPv6 地址 . . . . . . . . . . . . : 保密
   本地链接 IPv6 地址. . . . . . . . : fe80::f087:44c8:88bc:b041%11
   IPv4 地址 . . . . . . . . . . . . : 192.168.43.149
   子网掩码  . . . . . . . . . . . . : 255.255.255.0
   默认网关. . . . . . . . . . . . . : fe80::f805:ebff:fea5:4f38%11
                                       192.168.43.1

2.查看宿主机网卡

3.添加网卡

二、软件

4.获取mac地址

命令：ip link

[root@vbox ~]# ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/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 1000
    link/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 1000
    link/ether 08:00:27:19:ba:4d brd ff:ff:ff:ff:ff:ff
4: enp0s9: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
    link/ether 08:00:27:8b:f3:ec brd ff:ff:ff:ff:ff:ff

5.获取UUID

命令：nmcli con

[root@vbox ~]# nmcli con
NAME    UUID                                  TYPE      DEVICE 
enp0s3  40193217-26b5-4246-94f8-13449410d506  ethernet  enp0s3 
enp0s9  7571fda9-b1a6-3bf4-8920-94a7f625468c  ethernet  enp0s9 
enp0s8  fa9dd332-b1ff-3f86-ab1e-fa7c028d20b6  ethernet  enp0s8 

6.修改配置文件

命令：cd /etc/sysconfig/network-scripts
命令：cp ifcfg-enp0s3 ifcfg-enp0s9

ifcfg-enp0s3                                              ifcfg-enp0s9
