ubuntu24修改网络ip

环境:

OS:ubuntu 24.04

提前安装好 vim

apt install vim

 

1.将原来的网络配置文件备份到另外一个地方

root@hxl-VirtualBox:~# cd /etc/netplan/

root@hxl-VirtualBox:~#mv 01-network-manager-all.yaml /root/

 

2.创建一个新的配置文件

cd /etc/netplan/
vi 01-netcfg.yaml

network:
  version: 2
  renderer: networkd
  ethernets:
    enp0s3:
      dhcp4: no
      addresses:
        - 192.168.1.120/24
      routes:
        - to: default
          via: 192.168.1.1
      nameservers:
        addresses:
          - 8.8.8.8 # dns1
          - 8.8.4.4 # dns2

 

3.修改50-cloud-init.yaml

root@hxl-VirtualBox:/etc/netplan# more 50-cloud-init.yaml 
network:
  version: 2
  ethernets:
    enp0s3:
      dhcp4: false

这里修改为false

 

4.应用

sudo netplan apply # 应用网卡配置

sudo systemctl restart systemd-networkd # 重启网络

ip addr # 查看生效

ping www.baidu.com # 检查网络是否通
