ubuntu系统中一个网卡配置两个IP

在ubuntu系统环境中遇到需要对一个网卡配置2个ip的需求，特此记录
sudo vi /etc/network/interfaces
配置内容如下
auto eth0
auto eth0:0
auto eth0:1

iface eth0 inet static
address 192.168.1.1
netmask 255.255.0.0
gateway 192.168.1.254

iface eth0:0 inet static
address 192.168.1.2
netmask 255.255.0.0
gateway 192.168.1.254

iface eth0:1 inet static
address 192.168.1.3
netmask 255.255.0.0
gateway 192.168.1.254
设置网卡生效
sudo /etc/init.d/networking restart
