配置网卡地址

[lwk@anolis ~]$ sudo nmcli con mod enp0s3 ipv4.method manual ipv4.addresses 192.168.11.138/24 ipv4.gateway 192.168.11.1 ipv4.dns 223.6.6.6,223.5.5.5 connection.autoconnect yes
[sudo] password for lwk: 
[lwk@anolis ~]$

启用配置

[lwk@anolis ~]$ sudo nmcli con down enp0s3 && sudo nmcli con up enp0s3
Connection 'enp0s3' successfully deactivated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/1)
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/2)

这里，我们采用修改连接的方式对静态IP做了配置，我们也可以将原先的连接删除，然后再重新创建一个连接，其效果也是相同的。
