Ubuntu配置IP地址

从 17.01 开始之后的版本，都已放弃在/etc/network/interfaces 里固定IP的配置，而是改成 netplan 方式，配置文件是：/etc/netplan/01-network-manager-all.yaml

l  17.01之前的版本ip配置

root@yh-virtual-machine:~# cat /etc/network/interfaces

# interfaces(5) file used by ifup(8) and ifdown(8)

auto ens32

iface ens32 inet static

address 10.0.0.10

netmask 255.255.255.0

gateway 10.0.0.254

dns-nameservers 223.5.5.5

dns-nameservers 114.114.114.114

l  17.01之后的版本ip配置

root@yang-virtual-machine:~# cat /etc/netplan/01-network-manager-all.yaml
