要在 Ubuntu 系统上添加永久辅助 IP 地址，只需编辑 /etc/network/interfaces 文件并添加所需的 IP 详细信息。

# vi /etc/network/interfaces

# vi /etc/network/interfaces
 
# The loopback network interface
auto lo
iface lo inet loopback
 
# The primary network interface
auto eth0
iface eth0 inet static
        address 192.168.56.150
        netmask 255.255.255.0
        network 192.168.56.0
        broadcast 192.168.56.255
        gateway 192.168.56.1
 
auto eth0:1
iface eth0:1 inet static
        address 192.168.56.151
        netmask 255.255.255.0

保存并关闭文件，然后重启网络接口服务。

# service networking restart
或
# ifdown eth0:1 && ifup eth0:1

验证新添加的 IP 地址：

# ifconfig

如何在 Ubuntu 16.04 LTS 中临时添加辅助 IP 地址

正如本文开头所述，网络接口名称从 Ubuntu 15.10 就开始从 ‘ethX’ 更改为 ‘enXXXX’ (enp0s3)，所以，替换你的接口名称。
