# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto enp0s3
iface enp0s3 inet dhcp

# Host-Only network interface
auto enp0s8
iface enp0s8 inet static
address 192.168.56.100
netmask 255.255.255.0
gateaway 192.168.56.1

在VBox中安装虚拟机时，网卡enp0s8默认是没有配置的，这里手动配置一下。

$ sudo systemctl restart networking
# 或
$ sudo /etc/init.d/networking restart
