Part 1: nmcli查看网络信息

[root@server ~]nmcli con show[root@server ~]nmcli con show --active

[root@server ~]nmcli con show "eno16777736"

Part 2 : nmcli配置网络连接
为现有连接添加一个额外ip

[root@server ~]nmcli connection modify eno16777736 +ipv4.addresses 192.168.124.82/24[root@server ~]nmcli connection show eno16777736 |grep ipv4

定义一个名为exam-con的新连接，给予ip地址，网关和dns，使用静态ip

[root@server ~]nmcli connection add con-name exam-con ifname eno16777736 type ethernet ip4 10.0.8.11/24 gw4 10.0.8.254[root@server ~]nmcli connection modify exam-con ipv4.dns 10.0.8.253

检查结果

禁止自动启动

[root@server ~]# nmcli connection modify exam-con connection.autoconnect no[root@server ~]# nmcli connection modify eno16777736 connection.autoconnect yes
