方法1（需要重启才能生效）
打开，
$ sudo vim /etc/network/interfaces
如下修改，重启生效（使用 $ sudo service networking restart 无效），
# interfaces(5) file used by ifup(8) and ifdown(8) auto lo iface lo inet loopback #################################################### Add by User Start uto enp6s0 iface enp6s0 inet static address 192.168.1.20 netmask 255.255.255.0 #getway 192.168.1.1 # 一般不用设置 #################################################### Add by User End
方法2（不需要重启）推荐
打开，
$ sudo vim /etc/netplan/01-network-manager-all.yaml # 一般仅有一个 .yaml 文件
原始内容为，
# Let NetworkManager manage all devices on this system network: version: 2 renderer: NetworkManager
修改为固定 ip 地址 ，
# Let NetworkManager manage all devices on this system #network: # version: 2 # renderer: NetworkManager # ethernets: # enp6s0: # dhcp4: yes network: version: 2 ethernets: enp6s0: dhcp4: no addresses: [192.168.1.22/24] optional: true gateway4: 192.168.1.1 nameservers: addresses: [192.168.1.1]
执行，
$ sudo netplan apply
如果要还原更改为 DHCP，修改上述文件为，
# Let NetworkManager manage all devices on this system network: version: 2 renderer: NetworkManager ethernets: enp6s0: dhcp4: yes #network: # version: 2 # ethernets: # enp6s0: # dhcp4: no # addresses: [192.168.1.22/24] # optional: true # gateway4: 192.168.1.1 # nameservers: # addresses: [192.168.1.1]
再次执行，
$ sudo netplan apply
完。
