nmcli 设置网络配置

1> 查看设备和信息

nmcli device status
nmcli connection show
nmcli connection show --active
nmcli  -f  NAME,FILENAME connection show

2> 修改 connection-id
nmcli connection modify "Wired connection 1" connection.id net_eth0
nmcli connection modify "Wired connection 2" connection.id net_eth1


3> 通过connection-id 修改 等参数

nmcli connection modify net_eth0 ipv4.addresses "192.168.82.15/24"
nmcli connection modify net_eth0 ipv4.addresses "192.168.81.12/24" ipv4.gateway "192.168.81.1" ipv4.dns "8.8.8.8,1.1.1.1" ipv4.method manual 802-3-ethernet.speed 100 802-3-ethernet.duplex full 802-3-ethernet.auto-negotiate no

注意修改之后，需要重启才能生效
sudo nmcli connection down net_eth0
sudo nmcli connection up net_eth0
