1，文件准备：smbd nmbd smbpasswd smb.conf。获取所需的smb环境及文件

a, smb源码:https://download.csdn.net/download/u013301596/87353322

b,smb二进制文件及配置文件:https://download.csdn.net/download/u013301596/87353318

2，解压samba.zip压缩包，并拷贝解压目录到Android设备的 /data/data/目录下

3,启动smb服务

export TMPDIR=/data/data/samba/var/tmp/      设置TMPDIR环境变量

smbd -D 启动samba服务，

nmbd -D 启动samba网络服务

smbpasswd -a accountname 添加用户/设置密码

smb.conf文件：

[global]
interfaces = wlan0 eth0 lo usb0 br0
workgroup = WORKGROUP
server string = Samba on Android
netbios name = ANDROID
remote announce = 255.255.255.255
encrypt passwords = yes
security = user
restrict anonymous = 1
load printers = no
printcap name = /dev/null
disable spoolss = yes
deadtime = 5
delete readonly = yes
nt acl support = no
inherit permissions = yes
socket options = SO_SNDBUF=16384 SO_RCVBUF=16384
[test]
comment = Android /mnt/sdcard
path = /data/data/samba/var/tmp
force user = root
read only = no
writable = yes
browseable = yes
[sdcard]
vfs objects = fake_perms
comment = Android /mnt/sdcard
path = /mnt/sdcard
force user = root
read only = no
writable = yes
guest ok = no

4，客户端访问android设备的共享目录：

a,内核添加：CIFS （Common Internet File System）的支持

b,挂载共享目录：mount -t cifs -o username=xxxxxxx,password=xxxxxx //IP/test /mnt
