甲骨文云 Oracle Cloud Arm免费服务器Ubuntu服务器启用IPv6

由于系统默认无法使用IPv6 通过修改配置文件手动获取已经在Oracle中生成的IPv6地址。

将已经获取到的IPv6地址编辑进：/etc/netplan/50-cloud-init.yaml

vi /etc/netplan/50-cloud-init.yaml

删除原内容后添加以下内容：

注保留原：macaddress:后的MAC 地址内容，或在系统后台自行获取，或命令获取都可以。

# This file is generated from information provided by the datasource.  Changes
# to it will not persist across an instance reboot.  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:
        enp0s3:
            dhcp4: true
            dhcp6: false
            match:
                macaddress: 02:00:17:01:2e:*
            addresses:
              - 2603:c022:8001:*:*:*:*:*/128
              - 2603:c022:8001:*:*:*:*:*/128
              - 2603:c022:8001:*:*:*:*:*/128
              - 2603:c022:8001:*:*:*:*:*/128
              - 2603:c022:8001:*:*:*:*:*/128
              - 2603:c022:8001:*:*:*:*:*/128
              - 2603:c022:8001:*:*:*:*:*/128
            set-name: enp0s3
    version: 2

注：如果只有一个IPv6地址，就删除多余项。

编辑后保存退出。

sudo netplan apply

应用配置文件即完成。
