如题，现有需求，为一个server版本的Ubuntu18.04配置 IP 。

在网上查到了 Ubuntu18.04 桌面版本的配置方法：

https://www.cnblogs.com/sammei/p/ubuntu-dan-wang-ka-shuang-ip.html

$ cat /etc/network/interfaces

修改配置文件：

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 192.168.1.111
gateway 192.168.1.1
netmask 255.255.255.0

auto eth0:1
iface eth0:1 inet dhcp

启用对网卡 eth0 的新IP配置：

sudo ifup eth0:1

==============================================

18.04 server 版本：

给一个网卡配置两个固定IP:

配置网卡文件 /etc/netplan/50-cloud-init.yaml

# This file is generated from information provided by
# the datasource.  Changes to it will not persist across an instance.
# To disable cloud-init's network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
# network: {config: disabled}
network:
    ethernets:
        eth0:
                addresses: [192.168.100.100/24,172.18.139.54/24]
                gateway4: 192.168.100.1
                dhcp4: no
    version: 2
