NetworkManager Static IP

Configuration

[connection]
id=ens192
type=ethernet
interface-name=ens192
autoconnect=true

[ipv4]
method=manual
addresses=10.0.0.10/24
gateway=10.0.0.1
dns=223.5.5.5;8.8.8.8;
dns-search=

[ipv6]
method=ignore

chmod 600 /etc/NetworkManager/system-connections/ens34.nmconnection
chown root:root /etc/NetworkManager/system-connections/ens34.nmconnection

systemctl reload NetworkManager

systemctl restart NetworkManager

ip addr show ens34
ip route
cat /etc/resolv.conf

Fix

nmcli connection show

如果发现连的不是 ensxx，则 down：

nmcli connection down "Wired connection 2"

nmcli connection delete "Wired connection 2"

会自动连接到 ensxx，如果没有，则使用 modify 修改。
