准备：
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
debian@beaglebone:~$ sudo -s #密码：temppwd
root@beaglebone:~# userdel -r debian
root@beaglebone:~# vim /etc/ssh/sshd_config
将
#PermitRootLogin prohibit-password
改为
PermitRootLogin yes
#重启SSHD服务
root@beaglebone:~# /etc/init.d/ssh restart2，做必要的软件安装/卸载
root@beaglebone:~# apt-get update
root@beaglebone:~# apt-get install psmisc
root@beaglebone:~# apt-get autoremove apache2
root@beaglebone:~# apt-get autoremove nodejs
root@beaglebone:~# apt-get install -f
root@beaglebone:~# apt-get autoremove -f3，扩容
查找脚本路径
root@beaglebone:~# find / -iname "grow_partition.sh"
/opt/scripts/tools/grow_partition.sh
root@beaglebone:~# 查看当前磁盘剩余
root@beaglebone:~# df -hT
