[root@localhost ~]# ifup ens160

nmcli n
查看托管状态 enable为可用

nmcli n on 启用

解决

nmcli命令新增网卡并创建配置文件以及修改现有网卡地址信息

创建并配置

nmcli con add ifname enp1s0 type ethernet con-name ens1s0
ipv4.addresses 172.25.250.10/24 ipv4.gateway 172.25.250.254 ipv4.dns
172.25.250.254 ipv4.method manual

修改并设置

nmcli con mod ens1s0 ipv4.addresses 172.25.250.10/24
ipv4.gateway 172.25.250.254 ipv4.dns 172.25.250.254 ipv4.method manual
