Ubuntu Server 21.10设置静态IP

Ubuntu Server 21.10静态IP地址的设置和以前不同了.

• 经验证22.04该方案依旧可行.
• 默认动态IP地址对应的配置文件: /etc/netplan/*.yaml
• 设置固定ip地址
  如:192.168.1.2是本机IP，192.168.1.1是网关，f4:5b:11:4c:dc:bd是网卡的MAC地址.

# 此处文件名按照自己的实际情况来
sudo nano /etc/netplan/*.yaml

network:
  version: 2
  #renderer: networkd
  ethernets: 
    eth0:
      #link-local: []
      optional: true
      dhcp4: no
      addresses:
       - 192.168.1.2/24
      routes:  
        - to: default
          via: 192.168.1.1
      #match:
      #    macaddress: f4:5b:11:4c:dc:bd
      #set-name: eth0
      nameservers:
        addresses: [223.5.5.5,223.6.6.6,8.8.8.8,8.8.4.4]
        #search: []

• 然后执行命令应用设置

sudo netplan apply

• 重启系统

sudo reboot
