Raspberry Pi first boot up

从https://www.raspberrypi.org/downloads/raspbian/ 下载的raspbian的镜像,解压后用 Win32DiskImager解压到一张microSD卡上即可。

用hdmi连接显示器,显示器指示没有信号。需要把sd卡拿下来,编辑boot区的 config.txt:


但是装东西失败,显示disk full。

pi@raspberrypi ~ $ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/root 6.3G 6.0G 25M 100% /
devtmpfs 428M 0 428M 0% /dev
tmpfs 87M 336K 86M 1% /run
tmpfs 5.0M 0 5.0M 0% /run/lock
tmpfs 173M 0 173M 0% /run/shm
/dev/mmcblk0p5 60M 20M 41M 33% /boot
/dev/mmcblk0p3 27M 397K 25M 2% /media/SETTINGS

可以用 sudo apt-get purge wolfram-engine


可以运行 sudo raspi-config -> Expand Filesystem,重启后空间就回来了。

也可以用resize2fs /dev/mmcblk0p6 。但是没有试。

接下来是打开ssh,用ps显示ssh-server已经启动,apt-get重装openssh-server也不行。 ssh localhost也显示,connection refused。需要重新运行:
 sudo raspi-config

选择advanced setting,再选ssh就可以了。

  • Re-size to file-system to use the entire SD card in my case (8GB)
    First option in setup menu
  • Change the locale to match your location
    This is found under “Internationalization Options”
  • Change the timezone to match your location
    This is found under “Internationalization Options”
