命令详解

1. 使用nmcli重新回载网络配置

# nmcli c reload

2. 打开网卡

# nmcli c up <网卡>

2. 查看网卡信息

# nmcli con NAME UUID TYPE DEVICE ens33 36a7b552-ab17-4b2d-afd9-de96c6c935eb ethernet ens33

3. 显示具体的网络接口信息

# nmcli connection show xxx

4. 显示所有活动连接

# nmcli connection show --active

5. 删除一个网卡连接

# nmcli connection delete xxx

6. 给xxx添加一个IP（IPADDR）

# nmcli connection modify xxx ipv4.addresses 192.168.0.51

7. 给xxx添加一个子网掩码（NETMASK）

# nmcli connection modify xxx ipv4.addresses 192.168.0.51/24

8. IP获取方式设置成手动（BOOTPROTO=static/none）

# nmcli connection modify xxx ipv4.method manual

9. 添加一个ipv4

# nmcli connection modify xxx +ipv4.addresses 192.168.0.51/24

10. 删除一个ipv4

# nmcli connection modify xxx -ipv4.addresses 192.168.0.51/24

11. 添加DNS

# nmcli connection modify xxx ipv4.dns 114.114.114.114

12. 删除DNS

# nmcli connection modify xxx -ipv4.dns 114.114.114.114

13. 添加一个网关（GATEWAY）

# nmcli connection modify xxx ipv4.gateway 192.168.0.1

14. 网关和DNS一起写入

# nmcli connection modify xxx ipv4.dns 114.114.114.114 ipv4.gateway 192.168.0.1
