0:下载BeagleBone Black操作系统镜像:
https://debian.beagleboard.org/images/
当前最新的是:
https://debian.beagleboard.org/images/bone-debian-9.2-iot-armhf-2017-10-10-4gb.img.xz
下载后,解压得到:bone-debian-9.2-iot-armhf-2017-10-10-4gb.img
用dd命令或者Win32DiskImager写入到TF卡中,建议大于等于4G
1,登录到bbb,并切换到root权限
Xshell:\> ssh [email protected] #从路由器可以看到BeagleBone Black的IP password: #密码:temppwd [email protected]:~$ sudo -s #密码:temppwd [email protected]:~# userdel -r debian [email protected]:~# vim /etc/ssh/sshd_config 将 #PermitRootLogin prohibit-password 改为 PermitRootLogin yes #重启SSHD服务 [email protected]:~# /etc/init.d/ssh restart
2,做必要的软件安装/卸载
[email protected]:~# apt-get update [email protected]:~# apt-get install psmisc [email protected]:~# apt-get autoremove apache2 [email protected]:~# apt-get autoremove nodejs [email protected]:~# apt-get install -f [email protected]:~# apt-get autoremove -f
3,扩容
查找脚本路径 [email protected]:~# find / -iname "grow_partition.sh" /opt/scripts/tools/grow_partition.sh [email protected]:~# 查看当前磁盘剩余 [email protected]:~# df -hT Filesystem Type Size Used Avail Use% Mounted on udev devtmpfs 217M 0 217M 0% /dev tmpfs tmpfs 49M 5.6M 44M 12% /run /dev/mmcblk0p1 ext4 3.3G 1.6G 1.5G 52% / tmpfs tmpfs 244M 0 244M 0% /dev/shm tmpfs tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs tmpfs 244M 0 244M 0% /sys/fs/cgroup tmpfs tmpfs 49M 0 49M 0% /run/user/1000 tmpfs tmpfs 49M 0 49M 0% /run/user/0 [email protected]:~# 执行扩容脚本 [email protected]:~# /opt/scripts/tools/grow_partition.sh [email protected]:~# reboot #手动重新上电,开机 Xshell:\> ssh [email protected] [email protected]:~# df -hT #扩容成功 Filesystem Type Size Used Avail Use% Mounted on udev devtmpfs 217M 0 217M 0% /dev tmpfs tmpfs 49M 4.9M 44M 11% /run /dev/mmcblk0p1 ext4 7.4G 1.6G 5.5G 23% / tmpfs tmpfs 244M 0 244M 0% /dev/shm tmpfs tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs tmpfs 244M 0 244M 0% /sys/fs/cgroup tmpfs tmpfs 49M 0 49M 0% /run/user/0 [email protected]:~#
