树莓派安装和启动2

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)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
        loop  txqueuelen 1000  (Local Loopback)
        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

wlan0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        ether b8:27:eb:89:87:5d  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

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。
