Beaglebone Black基本操作（Debian）
1 Debian Beaglebone Black安装
###1.1 Image 下载
- Debian For BBB
- 我选择的是bone-debian-8.7-console-armhf-2017-01-30-2gb.img.xz
###1.2 准备EMMC烧录TF
- linux下
dd if=bone-debian-8.7-console-armhf-2017-01-30-2gb.img of=/dev/sdx bs=8M写入镜像 - linux系统下读取
rooft/boot/uEnv.txt
##enable BBB: eMMC Flasher:
cmdline=init=/opt/scripts/tools/eMMC/init-eMMC-flasher-v3.sh #### make this line enable
###1.3 插入TF卡，并从TF启动
###1.4 USB转串口连接
- GND(黑色） -> J1
- RXD(绿色） -> J4
- TXD(白色） -> J5
- 波特率：115200
- 用户名：root
- 密码：默认无
sudo minicom -o -D /dev/ttyUSB0 -b 115200
###1.5 使用完整TF卡容量
由于我使用的是32G的TF卡，而image文件是2G的镜像，df -h只能看到/分区只有2G容量，进行下述操作恢复完整容量：
cd /opt/scripts/tools
./grow_partition.sh
reboot
###1.6 Root登录，设置密码，并修改debian用户密码
passwd
passwd debian
###1.7 设置固定IP地址
目前该方法对于Debian7.x设置有效，但对于Debian8.x设置后，设备重启依然会走DHCP，再执行service networking restart又设置有效了
修改网络配置文件/etc/network/interfaces
sudo vi /etc/network/interfaces
找到相关内容添加下面的文字（我设置的ip地址为192.168.1.89）
# This file describes the network interfaces available on your system# and how to activate them.

###1.8 软件升级
apt-get update
apt-get upgrade
##2 安装ftp服务器，方便文件交互
###2.1 安装vsftpd
apt-get update
apt-get install vsftpd
###2.2 setup environment
cd /home/debian
mkdir ftp
chown debian ftp
chmod 777 ftp
###3.3 edit config file: vi /etc/vsftpd.conf
找到以下几行，做对应修改
anonymous_enable=NO ###change to NO
local_enable=YES ###uncomment
write_enable=YES ###uncomment
local_umask=022 ###uncomment
chroot_local_user=YES ###uncomment
chroot_list_enable=YES ###uncomment
chroot_list_file=/etc/vsftpd.chroot_list ###uncomment
local_root=/home/debian/ftp ###add
##3 ssh证书登录
###3.1 Windows
####3.1.1 key generate
- use puttygen generate rsa key, and public key
- save private key
- copy Pub key for openSSH, and save as authorized_keys
- use FTP to send authorized_keys to BBB
####3.1.2 server setup
cd ~
mkdir .ssh
cd .ssh
cat xxx/authorized_keys >> authorized_keys
####3.1.3 putty client setup
- Session -> IP & Port: 192.168.1.89 & 22
- Connection -> Data -> user name: file
- Connection -> SSH -> Auth: load the private key
- Session -> Saved Sessions: save all those setting as XXX
- Open
###3.2 Linux
####3.2.1 key generate
ssh-keygen -t rsa -b 1024
ssh-keygen -y -f ~/.ssh/id_rsa >> keytext
sudo ssh-keygen -f "/home/user/.ssh/known_hosts" -R 192.168.1.89 # add server to trust list
####3.2.2 server setup
cat keytext >> authorized_keys
####3.2.3 client login
ssh user@192.168.1.88
###3.3 More safe login setup of server
close password login port using ssh: vi /etc/ssh/sshd_config
PasswordAuthentication no ### change
