为Ubuntu 22.04设置静态IP（NetPlan）

发表于 分类于 阅读次数：
使用NetPlan工具，为Ubuntu 22.04设置静态IP

在 Ubuntu 服务器 22.04 中，网络由 netplan 程序控制，因此我们将使用 netplan 在 Ubuntu 服务器上配置静态 IP 地址。

修改netplan配置文件

修改：/etc/netplan/​00-installer-config.yaml配置文件：

默认配置如下：

1

# This is the network config written by 'subiquity'
network:
  ethernets:
    ens160:
      dhcp4: true
      dhcp-identifier: mac
  version: 2

按照需求修改如下：

1

# This is the network config written by 'subiquity'
network:
  ethernets:
    ens160:
      addresses:
        - 192.168.31.123/24
      nameservers:
        addresses: [114.114.114.114, 8.8.8.8]
      routes:
        - to: default
          via: 192.168.31.1
      dhcp-identifier: mac
    ens192:
      addresses:
        - 10.0.0.100/24
  version: 2

应用新的配置
