Ubuntu一块网卡配置多个IP地址

命令行

sudo ifconfig eth0:0 192.168.1.100/24 up
sudo ifconfig eth0:1 192.168.2.123/24 up

重启后失效

修改/etc/network/interfaces文件，永久生效

auto eth0:0
iface eth0:0 inet static
	address 192.168.1.100
	netmask 255.255.255.0
	gateway 192.168.1.1
	
auto eth0:1
iface eth0:1 inet static
	address 192.168.2.22
	netmask 255.255.255.0
	gateway 192.168.2.1
	
auto eth0:2
iface eth0:2 inet static
	address 192.168.3.22
	netmask 255.255.255.0
	gateway 192.168.3.1
