sudo nano /etc/network/interfaces.d/eth0
# maybe ethX

allow-hotplug eth0
iface eth0 inet static
address 192.168.1.5
network 192.168.1.1
netmask 255.255.255.0
gateway 192.168.1.1

或者使用流行的nmcli命令

sudo nmcli -p connection show

返回应该类似

NetworkManager connection profiles
NAME UUID TYPE DEVICE
Wired connection 1 bd220d18-7d6a-36a5-9820-4f67de2c01fc ethernet eth0
mywifi 2359440b-8991-4c86-a905-b011dced4587 wifi wlan0
lo c29ba7c5-98ff-4fa0-8d8e-06b30b8ec384 loopback lo

假设修改以太网

sudo nmcli c mod "Wired connection 1" ipv4.addresses 192.168.1.5/24 ipv4.method manual
# multi ip address
sudo nmcli c mod "Wired connection 1" ipv4.addresses "192.168.1.5/24, 192.168.1.6/24, 10.0.0.222/24" ipv4.method manual

sudo nmcli con mod "Wired connection 1" ipv4.gateway 192.168.1.1

sudo nmcli con mod "Wired connection 1" ipv4.dns "8.8.8.8,8.8.4.4"

# reboot network
sudo nmcli c down "Wired connection 1" && sudo nmcli c up "Wired connection 1"
nmcli -p connection show "Wired connection 1"

# 恢复到自动分配
sudo nmcli con modify "Wired connection 1" ipv4.method auto
sudo nmcli c down "Wired connection 1" && sudo nmcli c up "Wired connection 1"
