ubuntu2204使用netplan配置网络信息

文章目录

前言

ubuntu2204操作系统通过netplan配置网络信息
配置文件：/etc/netplan/00-installer-config.yaml
命令工具：netplan

一、使用dhcp方式配置

network:
  ethernets:
    ens3:
      dhcp4: true
  version: 2

在这里插入图片描述

备注：要注意冒号后面要带一个空格，在使用编辑器编辑的时候，要注意格式。

二、使用手动配置方式

配置信息：

  • IP：192.168.150.55
  • NETMASK：24
  • 网关：192.168.150.254
  • DNS：114.114.114.114, 8.8.8.8
network:
  ethernets:
    ens3:
      addresses: [192.168.150.55/24]          # 设置静态IP地址和掩码
      gateway4: 192.168.150.254                # 设置网关地址
      dhcp4: false                            # 禁用dhcp
      nameservers:
        addresses: [114.114.114.114, 8.8.8.8] # 设置主、备DNS
  version: 2

使用命令使得配置信息生效
