1、用nmcli命令生成网卡配置文件，此文件保存路径 /etc/sysconfig/network-scripts/ifcfg-lan1
nmcli conn add con-name lan1 type ethernet autoconnect yes ifname eno16777736 ip4 10.1.128.10/16 gw4 10.1.128.2
2、用nmcli添加dns
nmcli conn modify lan1 ipv4.dns 202.96.128.86
nmcli conn modify lan1 +ipv4.dns 202.96.128.166
3、添加永久静态网关
vim /etc/sysconfig/network-scripts/route-lan1
10.2.0.0/16 via 10.1.128.3 dev eno16777736
10.3.0.0/16 via 10.1.128.3 dev eno16777736
4、重启network服务立即生效
systemctl restart network
