我要评论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
eth0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
ether b8:27:eb:dc:d2:08 txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)

lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536

wlan1: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
ether 44:33:4c:e8:d1:3c txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
pi@raspberrypi:~$
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-PSK
psk="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。
