- nmcli配置多會話
- 繫結兩塊網絡卡

實驗1
網絡卡支援多會話功能，由於工作環境不同，需要配置不同的網路：如在家裡使用使用DHCP獲取，在公司使用固定ip，如果使用修改方式比較麻煩，配置多會話功能，在不同場景啟用即可。
實驗環境：
centos7、home：DHCP、company：static，自動連線
配置過程：配置資訊會儲存至/etc/sysconfig/network-scripts/ifcfg-name- 新增會話

修改IP地址
如果不修改預設為自動分配；
[[email protected] ~]# nmcli connection modify company ipv4.addresses 172.16.0.10/16 ipv4.method manual
還可以配置DNS、gateway... - 檢視效果
