1、树莓派起来了，顺手改个密码：
pi@raspberrypi:~$ passwd pi
Changing password for pi.
Current password:
New password:
Retype new password:
passwd: password updated successfully
pi@raspberrypi:~$
2、检查下wifi
pi@raspberrypi:~$ ifconfig

3、配置下wifi
sudo vi /etc/wpa_supplicant/wpa_supplicant.conf
增加下自己的网络配置
network={ssid="your SSID"key_mgmt=WPA-PSKpsk="your password"
}
4、reboot下
pi@raspberrypi:~$ sudo reboot
好了，起来之后，等一会儿，ifconfig就能看到wlan1有IP了。
