适用于Ubuntu 17.04及更高版本

配置文件 ​

  1. 进入 netplan 配置文件目录

    通常在 /etc/netplan/ 目录下。 一般有一些不同的名字，但是都是yaml文件

  2. 在编辑前先拷贝一份，以防万一

    shell
    #   没有则创建
touch 01-netcfg.yaml
cp 01-netcfg.yaml 01-netcfg.yaml.bak
    #   没有则创建
touch 01-netcfg.yaml
cp 01-netcfg.yaml 01-netcfg.yaml.bak

  3. 查看本地使用的网络模式

    如果是有线连接一般就是eth0,wifi就是wlan0

    注(大坑): wifi网络和以太网网络要配置的网络模式不一样，网络上的文章都基本只说了以太网（网线）模式

    shell
    nmcli device show
    nmcli device show

    查看顶部的 GENERAL.DEVICE是什么，下面配置文件要用

  4. 配置netplan的yaml文件

    shell
    sudo nano /etc/netplan/01-netcfg.yaml
    sudo nano /etc/netplan/01-netcfg.yaml

    以太网模式(ethernets): ​

    shell
      network:
  version: 2
  renderer: networkd
#   以太网模式 使用 ethernets:
  ethernets:
    eth0:
      dhcp4: true
  ## 可以ip a查看以太网连接名称
  ## addresses添加网络掩码，如192.168.56.3/24
      addresses: [ 192.168.52.192/24 ]
      routes:
        - to: "default"
          via: "192.168.52.1"
      nameservers:
        search: [ mydomain , otherdomain ]
        addresses: [ 192.168.52.1 , 114.114.114.114 ]
      optional: true
      network:
  version: 2
  renderer: networkd
#   以太网模式 使用 ethernets:
  ethernets:
    eth0:
      dhcp4: true
  ## 可以ip a查看以太网连接名称
  ## addresses添加网络掩码，如192.168.56.3/24
      addresses: [ 192.168.52.192/24 ]
      routes:
        - to: "default"
          via: "192.168.52.1"
      nameservers:
        search: [ mydomain , otherdomain ]
        addresses: [ 192.168.52.1 , 114.114.114.114 ]
      optional: true

    WIFI模式(wifis): ​

    shell
    network:
  version: 2
  renderer: networkd
  ethernets:
    eth0:
      dhcp4: true
      ## 可以ip a查看以太网连接名称
      ## addresses添加网络掩码，如192.168.56.3/24
  #      addresses: [ 192.168.52.192/24 ]
  #      # gateway4: 10.10.10.1
  #      ## gateway4已经废弃，推荐使用routes
  #      routes:
  #        - to: "default"
  #          via: "192.168.52.1"
  #      nameservers:
  #        search: [ mydomain , otherdomain ]
  #        addresses: [ 192.168.52.1 , 114.114.114.114 ]
  #      optional: true
  wifis:
    wlan0:
      dhcp4: false
      addresses:
        - 192.168.52.192/24
      routes:
        - to: "default"
          via: "192.168.52.1"
      nameservers:
        search: [ mydomain , otherdomain ]
        addresses: [ 192.168.52.1 , 114.114.114.114 ]
      access-points:
        "your_ssid":
          password: 'your_wifi_pwd'
    network:
  version: 2
  renderer: networkd
  ethernets:
    eth0:
      dhcp4: true
      ## 可以ip a查看以太网连接名称
      ## addresses添加网络掩码，如192.168.56.3/24
  #      addresses: [ 192.168.52.192/24 ]
  #      # gateway4: 10.10.10.1
  #      ## gateway4已经废弃，推荐使用routes
  #      routes:
  #        - to: "default"
  #          via: "192.168.52.1"
  #      nameservers:
  #        search: [ mydomain , otherdomain ]
  #        addresses: [ 192.168.52.1 , 114.114.114.114 ]
  #      optional: true
  wifis:
    wlan0:
      dhcp4: false
      addresses:
        - 192.168.52.192/24
      routes:
        - to: "default"
          via: "192.168.52.1"
      nameservers:
        search: [ mydomain , otherdomain ]
        addresses: [ 192.168.52.1 , 114.114.114.114 ]
      access-points:
        "your_ssid":
          password: 'your_wifi_pwd'

重启网络 ​

  1. 应用配置并且重启网络
    shell
    sudo netplan apply
sudo systemctl restart Networkmanager
    sudo netplan apply
sudo systemctl restart Networkmanager
  2. 查看静态ip是否配置成功
    shell
    # 喜欢哪个运行哪个
ifconfig

ip addr show
    # 喜欢哪个运行哪个
ifconfig

ip addr show
