【原创】ubuntu18修改IP地址

打开网络配置文件

sudo vi /etc/network/interfaces
1

结果发现如下内容：

# ifupdown has been replaced by netplan(5) on this system.  See
# /etc/netplan for current configuration.
# To re-enable ifupdown on this system, you can run:
#    sudo apt install ifupdown

接下来，查看 /etc/netplan文件夹

tacgui@tacgui:~$ ll /etc/netplan/
total 12
drwxr-xr-x  2 root root 4096 Oct 11 08:11 ./
drwxr-xr-x 98 root root 4096 Aug 23  2019 ../
-rw-r--r--  1 root root  348 Oct 11 08:11 01-netcfg.yaml

里面只有一个文件 01-netcfg.yaml
打开 01-netcfg.yaml

sudo vi /etc/netplan/01-netcfg.yaml

原来，这里修改IP地址
