Ubuntu18.04 server 双网卡，一个设置为静态IP， 一个设置为动态IP

操作目的如题：

修改网络配置文件：

sudo vim /etc/netplan/50-cloud-init.yaml

修改内容如下：

# 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:
        enp7s0:
            dhcp4: true
            nameservers:
                addresses:
                - 202.118.66.6
                search: []
            optional: true

        enp8s0:
            addresses:
            - 192.168.11.66/24
            gateway4: 192.168.11.254
            nameservers:
                addresses:
                - 202.118.66.6
                search: []
            optional: true

    version: 2

编辑完后，执行命令：

sudo netplan apply

其中， 网卡  enp7s0  设置为动态获取ip， 网卡 enp8s0  设置为静态ip 。
