1. 重要：Ubuntu 18.04 網絡配置與Ubuntu 16.04網絡配置變動較大

2.修改網絡配置文件 /etc/netplan/01-netcfg.yaml

$ sudo vim /etc/netplan/01-netcfg.yaml

修改模板

# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
  version: 2
  renderer: networkd
  ethernets:
  # 網卡名
    ens18:
    # 是否使用 dhcp4
     dhcp4: no
     # ip 地址
     addresses: [A.A.A.A/24]
     # 網關
     gateway4: G.G.G.G
     # dns 域名解析服務器地址
     nameservers:
       addresses: [N.N.N.N]

3.應用網絡配置

$ sudo netplan apply

如果應用失敗，可以查看錯誤日誌並調試

$ sudo netplan --debug apply
