插上网线，在 pc 上使用 nmap 之类扫出 ip 地址
使用 ip 地址 ssh 上去，用户名和密码都是 root
安装 wireless，参照http://raspberrypi.stackexchange.com/a/7992
将 wireless 设定为开机启动。http://unix.stackexchange.com/a/83108
显示 cpu 温度：https://wiki.archlinux.org/index.php/Raspberry_Pi#Temperature
安装 apache 和 php。http://kiros.co.uk/blog/installing-lamp-linuxapachemysqlphp-on-the-raspberry-pi/

最终效果

pi@raspberrypi ~ $ cat /etc/network/interfaces
auto lo

配置相机

挂载 samba，修改/etc/fstab 文件 //192.168.12.10/cloud /home/pi/mnt/192.168.12.10 cifs username=devin,password=123456,uid=1000 0 0

pi@raspberrypi ~ $ pwd
/home/pi
pi@raspberrypi ~ $ cat camera.sh
#!/bin/bash

DATE=$(date +"%Y-%m-%d_%H%M")

raspistill -vf -hf -o /home/pi/mnt/192.168.12.10/$DATE.jpg
pi@raspberrypi ~ $ cat /etc/cron.d/camera
*       *       *       *       *       pi      /home/pi/camera.sh

时间不正确

原型 raspi-config 重新设定一下 time zone，比较将 time zone 设定为 shanghai，然后时间就恢复正确了。

目前不确定是什么问题引起的时间不正确的问题。
