弹性网络接口

弹性网络接口 - Amazon Elastic Compute Cloud

如何让我的辅助网络接口在我的 Ubuntu Amazon 弹性计算云 (Amazon EC2) 实例中工作？

让辅助网络接口在 Ubuntu EC2 实例中工作

配置 Ubuntu 18.04

Ubuntu 18.04 已将其网络配置切换为 Netplan。以下示例使用了 Netplan 配置。请注意，Netplan 使用了 YAML 格式，因此缩进很重要。下面的示例使用了一个双空格缩进。

1.为辅助接口创建一个配置文件：

vim /etc/netplan/51-eth1.yaml

2.将以下行添加到 51-eth1.yaml 文件。

network:
    ethernets:
        eth0:
            addresses: [172.31.23.111/24,172.31.16.119/24]
            dhcp4: true
            dhcp6: false
            match:
