1、查看连接情况

[root@node1 ~]# nmcli connection show
NAME    UUID                                  TYPE      DEVICE 
ens33   3d2b9aad-a175-46ee-abee-ada67cd7a6c3  ethernet  ens33  
virbr0  ce5b08c2-eb1a-4d60-8b8d-716935662f71  bridge    virbr0

2、配置ip地址

[root@node1 ~]# nmcli connection modify ens33 ipv4.addresses 192.168.8.120/24 ipv4.gateway 192.168.8.1 connection.autoconnect yes ipv4.method manual

3、启动网络服务

[root@node1 ~]# nmcli connection up ens33
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/4)
[root@node1 ~]#

4、查看连接状态

[root@node1 ~]# nmcli connection show ens33
