ubuntu配置网络信息

环境:
Os:18.04.1

1.备份配置文件
root@11g:~# cd /etc/netplan
root@11g:/etc/netplan#
root@11g:/etc/netplan# cp 01-network-manager-all.yaml bak_01-network-manager-all.yaml

2.配置静态ip

# Let NetworkManager manage all devices on this system
network:
  ethernets:
    enp0s3:
      addresses: [192.168.56.101/24]
      gateway4: 192.168.56.1
      dhcp4: no
      dhcp6: no
      nameservers:
              addresses: [8.8.8.8,8.8.4.4]
      optional: true
  version: 2

3.配置完成后，应用命令：

root@11g:/etc/netplan# netplan apply
/etc/netplan/01-network-manager-all.yaml:12:4: Invalid YAML: inconsistent indentation:
   version: 2      
   ^

我这里上格式问题,调整后再次执行,最后文件内如如下:

root@11g:/etc/netplan# more 01-network-manager-all.yaml 
# Let NetworkManager manage all devices on this system
network:
  ethernets:
    enp0s3:
      addresses: [192.168.56.101/24]
      gateway4: 192.168.56.1
      dhcp4: no
      dhcp6: no
      nameservers:
        addresses: [8.8.8.8,8.8.4.4]
      optional: true
  version: 2
