ubuntu20.04配置静态ip

配置文件在/etc/netplan/下面，cd进去看具体文件名，不同的人可能文件名不一样，

vim打开之后一般是

# Let NetworkManager manage all devices on this system
network:
  ethernets:
    enp0s160:   # 配置的网卡的名称
      dhcp4: true   # 打开dhcp4
  renderer: NetworkManager

修改成下面这样

# This is the network config written by 'subiquity'
network:
  ethernets:
    ens160:
      dhcp4: false
      addresses: [192.168.1.105/24]  #ip和掩码
      optional: true
      gateway4: 192.168.1.1  #网关
      nameservers:
        addresses: [192.168.1.1,144.144.144.144]  #DNS服务器
  version: 2
  renderer: NetworkManager

然后应用

sudo netplan apply
