现在我们来配置网卡用静态ip使得树莓派通过usb共享电脑端的网络
(类似于使用USB网卡来共享网络)首先我们来为树莓派设置网络参数：

vi /etc/network/interfaces末行添加

allow-hotplug usb0
iface usb0 inet static
        address 192.168.2.2
        netmask 255.255.255.0
        network 192.168.2.0
        broadcast 192.168.2.255
        gateway 192.168.2.1

这里我们设置的是一个2的网段，树莓派主机的ip为192.168.2.2。当树莓派通过usb连接到电脑上时我们可以在Mac的网络设置中看到一个RNDIS/Ethernet Gadget的网卡我们设置其参数为这里写图片描述
注意这里的ip为192.168.2.1相当于小型局域网中的网关主机，此处也确实如此，树莓派以此ip为网关。此时直接reboot树莓派，有很多人使用
