Ubuntu 22.04 修改IP_ubuntu22.04修改ip地址

Ubuntu 22.04 修改为静态IP

此处使用VM 自动获取IP后修改为静态IP

通常ens打头的为对应需要修改的网卡地址

tester@testerserver:~$ cat /etc/netplan/00-installer-config.yaml
1

将次文件的内容修改为

network:
  ethernets:
    # ip addr 默认 ens33
    ens33:
      dhcp4: false
      # IP 地址
      addresses: [192.168.79.8/24]
      routes: 
        - to: default
          # 网关 对应宿主机提供的IP
          via: 192.168.79.2
      nameservers:
        # DNS 地址
        addresses: [8.8.8.8,114.114.114.114]
      dhcp6: false 
  version: 2
