Macbook中使用Virtualbox 搭建Ubuntu20.4 server 设置静态IP

macbook 的虚拟机安装 Ubuntu 的网络设置和 window 不太一样，网上这方面的记录比较少，这里总结一下。

• gateway4 has been deprecated, use default routes instead.

kendall@kendall:/etc/NetworkManager$ sudo netplan apply

** (generate:3580): WARNING **: 09:04:21.545: `gateway4` has been deprecated, use default routes instead.
See the 'Default routes' section of the documentation for more details.

** (process:3578): WARNING **: 09:04:22.162: `gateway4` has been deprecated, use default routes instead.
See the 'Default routes' section of the documentation for more details.
Failed to start NetworkManager.service: Unit NetworkManager.service not found.

问题解决，将 gateway4 改成 routes ，具体见下文的静态 IP 配置。

• Unit network-manager.service not found.

问题解决

sudo apt-get install network-manager

然后修改/etc/NetworkManager/NetworkManager.conf ,

[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=true

[device]
wifi.scan-rand-mac-address=no

这里需要设置两个网卡，一个用来连接互联网，一个用来进行 ssh 连接。

具体步骤见下图

• 设置主机网络管理器
  
  
• 添加网卡

• 安装 network-manager

sudo apt-get install network-manager

• 修改/etc/NetworkManager/NetworkManager.conf ,

[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=true

[device]
wifi.scan-rand-mac-address=no

vim /etc/netplan/00-installer-config.yaml 

network:
  version: 2
  renderer: NetworkManager
  ethernets:
    enp0s3:
      dhcp4: yes
      dhcp6: yes
    enp0s8:
      dhcp4: no
      dhcp6: no
      addresses: [192.168.56.103/24]
      routes:
      - to: default
        via: 192.168.56.1
      nameservers:
        addresses: [8.8.8.8]

注意将 enp0s3 和 enp0s8 修改成自己的。然后就是注意空格和对齐

• 最后

sudo netplan apply 

以上就是全部步骤啦，可以使用 ping www.baidu.com 查看是否能联网，

在 Macbook 终端使用 ssh kendall@192.168.56.103 测试连接。
