3, start to install linux

During the installation process, you need to set the IP and gateway of eth0

 

192.168.56.1

 

 

4, set ip

 

/etc/sysconfig/network-scripts/ifcfg-eth0, corresponding to host-only network card

 

 

DEVICE=eth0
TYPE=Ethernet
UUID=db0befdd-0ed5-47a4-b64d-d1b58806dae0
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
DEFROUTE = yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME="System eth0"
HWADDR=08:00:27:6C:2D:FA #Virtual machine network card mac
IPADDR=192.168.56.11 #IP
PREFIX=24
GATEWAY=192.168.56.1 #host-only ip

 

 

/etc/sysconfig/network-scripts/ifcfg-eth1, corresponding to NAT network card, dhcp automatically obtains IP without modification.
