命令详解

  1. 使用nmcli重新回载网络配置
# nmcli c reload
  1. 打开网卡
# nmcli c up <网卡>
  1. 查看网卡信息
# nmcli con 
NAME   UUID                                  TYPE      DEVICE 
ens33  36a7b552-ab17-4b2d-afd9-de96c6c935eb  ethernet  ens33 
  1. 显示具体的网络接口信息
# nmcli connection show xxx
  1. 显示所有活动连接
# nmcli connection show --active
  1. 删除一个网卡连接
# nmcli connection delete xxx
  1. 给xxx添加一个IP(IPADDR)
# nmcli connection modify xxx ipv4.addresses 192.168.0.51
  1. 给xxx添加一个子网掩码(NETMASK)
# nmcli connection modify xxx ipv4.addresses 192.168.0.51/24
  1. IP获取方式设置成手动(BOOTPROTO=static/none)
# nmcli connection modify xxx ipv4.method manual
  1. 添加一个ipv4
# nmcli connection modify xxx +ipv4.addresses 192.168.0.51/24
  1. 删除一个ipv4
# nmcli connection modify xxx -ipv4.addresses 192.168.0.51/24
  1. 添加DNS
# nmcli connection modify xxx ipv4.dns 114.114.114.114
  1. 删除DNS
# nmcli connection modify xxx -ipv4.dns 114.114.114.114
  1. 添加一个网关(GATEWAY)
# nmcli connection modify xxx ipv4.gateway 192.168.0.1
  1. 网关和DNS一起写入
# nmcli connection modify xxx ipv4.dns 114.114.114.114 ipv4.gateway 192.168.0.1
