BeagleBone Black 开机初始化操作

标签：beaglebone black 开机初始化操作

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 debian@172.16.1.144 #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 restart

2，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 -f

3，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
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
root@beaglebone:~# 

执行扩容脚本
root@beaglebone:~# /opt/scripts/tools/grow_partition.sh
root@beaglebone:~# reboot    #手动重新上电，开机
Xshell:\> ssh root@172.16.1.144
root@beaglebone:~# 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
