ubuntu 18.04修改静态ip地址

1. 确认网卡名称

ip a　　#有ens开头的网卡，比如我的是ens160

2. DHCP的方式获取动态ip

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

network:
  ethernets:
      ens160:
          dhcp4: yes
          addresses: []

  version: 2

3. 设置静态ip

vim /etc/netplan/00-installer-config.yaml
network:
  ethernets:
      ens160:
          dhcp4: no
          addresses: [172.16.200.6/24]
          optional: true
          gateway4: 172.16.200.254
          nameservers:
              addresses: [202.96.128.86,202.96.128.166]


  version: 2

4. 应用新的网卡配置信息

netplan apply

5. 测试网络连通性
