ubuntu 18.04以后如何修改固定ip和固定dns
ubuntu 18.04以后如何修改固定ip和固定dns这个问题可能刚接触18.04系统的还不知道怎么修改，我们都知道老版本可能很简单，就是修改：
sudo vim /etc/network/interfaces
输入类似：
输入：
auto eth0
iface eth0 inet static
address 192.168.2.1
gateway 192.168.2.254
netmask 255.255.255.0
就可以搞定了
但是自ubuntu 18.04开始，这样就不行啦，/etc/network/interfaces文件已经忽略
如果你先在ubuntu 18.04系统中使用固定ip，包括固定dns，请参考如下修改：
sudo vim /etc/netplan/50-cloud-init.yaml
或者在/etc/netplan的目录下，其他.yaml文件

搞定。
