beaglebone black 開機初始化操作
0：下載BeagleBone Black操作系統鏡像：
https://debian.beagleboard.org/images/
當前最新的是：
https://debian.beagleboard.org/images/bone-debian-9.2-iot-armhf-2017-10-10-4gb.img.xz
下載後，解壓得到：bone-debian-9.2-iot-armhf-2017-10-10-4gb.img
用dd命令或者Win32DiskImager寫入到TF卡中，建議大於等於4G
1，登錄到bbb，並切換到root權限
Xshell:\> ssh [email protected] #從路由器可以看到BeagleBone Black的IP password: #密碼：temppwd debian@beaglebone:~$ sudo -s #密碼：temppwd root@beaglebone:~# userdel -r debian root@beaglebone:~# vim /etc/ssh/sshd_config 將 #PermitRootLogin prohibit-password 改為 PermitRootLogin yes #重啟SSHD服務 root@beaglebone:~# /etc/init.d/ssh restart
2，做必要的軟件安裝/卸載
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，擴容
查找腳本路徑 root@beaglebone:~# find / -iname "grow_partition.sh" /opt/scripts/tools/grow_partition.sh root@beaglebone:~# 查看當前磁盤剩余 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:~# 執行擴容腳本 root@beaglebone:~# /opt/scripts/tools/grow_partition.sh root@beaglebone:~# reboot #手動重新上電，開機 Xshell:\> ssh [email protected] root@beaglebone:~# df -hT #擴容成功 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 root@beaglebone:~#
