服务器默认是DHCP获取一个IP，由于绑定了多个IP到这台服务器，需要修改配置文件来绑定这些IP。

操作步骤

网络配置文件/etc/netplan/50-cloud-init.yaml默认配置如下：

network:
    version: 2
    ethernets:
        enp0s6:
            dhcp4: true
            match:
                macaddress: 02:00:17:00:ba:a5
            set-name: enp0s6

修改 dhcp4值 为false
增加 addresses 值为"IP/子网掩码"

network:
    version: 2
    ethernets:
        enp0s6:
            dhcp4: false
            match:
                macaddress: 02:00:17:00:ba:a5
            set-name: enp0s6
            addresses:
                - 10.0.0.101/24
                - 10.0.0.121/24
                - 10.0.0.134/24
