```nmcli connection
NAME UUID TYPE DEVICE
ens33 a92fa07b-9b68-4d2b-a2e7-e55146099b1b ethernet ens33
ens36 418da202-9a8c-b73c-e8a1-397e00f3c6b2 ethernet ens36
nmcli con xxx ```
显示具体的网络接口信息
nmcli connection show xxx
显示所有活动连接
nmcli connection show --active
删除一个网卡连接
nmcli connection delete xxx
给xxx添加一个IP(IPADDR)
nmcli connection modify xxx ipv4.addresses 192.168.0.58
给xxx添加一个子网掩码(NETMASK)
nmcli connection modify xxx ipv4.addresses 192.168.0.58/24
IP获取方式设置成手动(BOOTPROTO=static/none)
nmcli connection modify xxx ipv4.method manual
添加一个ipv4
nmcli connection modify xxx +ipv4.addresses 192.168.0.59/24
删除一个ipv4
nmcli connection modify xxx -ipv4.addresses 192.168.0.59/24
添加DNS
nmcli connection modify xxx ipv4.dns 114.114.114.114
删除DNS
nmcli connection modify xxx -ipv4.dns 114.114.114.114
添加一个网关(GATEWAY)
nmcli connection modify xxx ipv4.gateway 192.168.0.2
可一块写入:
nmcli connection modify xxx ipv4.dns 114.114.114.114 ipv4.gateway 192.168.0.2
使用nmcli重新回载网络配置
nmcli c reload
如果之前没有xxx的connection,则上一步reload后就已经自动生效了
nmcli c up xxx
