把闲置的安卓手机做成smb服务器

2025-04-04

最近买了一个MacBook Air，奈何囊中羞涩只买得起256G的版本，到手之后把开发环境搭建好已经没有啥剩余空间，看了下上次换下来的安卓手机，8 + 256的配置，这200多G的空间已经快赶上我电脑了，这不利用起来真的是天理难容啊。

安卓软件方案

最开始是打算找一下支持远程访问的安卓软件的，比如小米的ftp服务，ftp服务搭建好了直接挂在到macOS上，打开视频会全量下载完成之后才会播放，用来传输文件还好，但是做存储体验太差了。

去然后找了一堆软件，比如 Mix文件管理器 、SMB Server 开启的ftp服务倒是没啥问题，开启smb服务就根本连接不上，还有lan drive这些比较老的软件根本运行不起来咯。

termux 服务方案（依赖 root）

安卓设备本来就是一个运行在Linux上的系统，Linux可玩的那可就多了，以前玩过Termux跑一些机器人服务，先直接按照Linux的方案把samba服务跑起来就行。

GitHub上直接下载最新发行版安装好 https://github.com/termux/termux-app/releases

Termux 配置

打开termux软件，切换源到国内

1	termux-change-repo

更新应用源

1	apt update

开启存储访问权限

1	termux-setup-storage

安装必要服务

1	pkg install -y vim openssh openssl samba root-repo tsh

电脑ssh登陆进行配置

我一般习惯通过共钥直接登陆，复制电脑上的~/.ssh/id_rsa.pub的内容，发送到设备上

1	echo $id_rsa.pub >> ~/.ssh/known_hosts

把电脑的公钥配置到安卓设备上，就不用用户密码直接登陆了。

直接运行sshd就会开启远程ssh服务

sshd

查看设备ip地址

ifconfig

然后直接登陆（termux 默认端口为8022）

1	ssh 192.168.1.* -p 8022

samba配置

安装好samba服务后/data/data/com.termux/files/usr/share/doc/samba目录下默认会有个smb.conf.example文件，通过这个文件修改几处配置，然后通过这个文件启动就可以开启smb服务了。

先复制一份出去，然后再进行编辑

mkdir /data/data/com.termux/files/usr/etc/samba
# copy 一份文件后编辑 
cp /data/data/com.termux/files/usr/share/doc/samba/smb.conf.example /data/data/com.termux/files/usr/etc/samba/smb.conf

对配置文件进行编辑

#============================ Share Definitions ==============================

; replace /storage/ext_sd with the path to your external card in /storage

第47行端口改为139和445，第53行的map to guest = Never改为map to guest = Bad User, 第100行下嘛的分享路径和权限按需配置即可。如果需要限制访问IP可以打开第21行注释，建议放开同网段下所有局域网:

1	hosts allow = 192.168.1.0/24

如果需要加密访问就保持53行map to guest = Never，然后再termux中进入root用户，使用smbpasswd 创建用户和密码。然后再分享的目录配置里面新增管理用户, 关闭来宾访问。

1 2	su /data/data/com.termux/files/usr/bin/smbpasswd -a Tia

smb.conf

guest ok = no
admin users = Tia
valid users = Tia

每次启动输一堆命令很麻烦，直接新建一个sh脚本吧

echo '#!/bin/bash
sudo /data/data/com.termux/files/usr/bin/smbd -s /data/data/com.termux/files/usr/etc/samba/smb.conf
' > setupsmb.sh

之后启动termux后直接输入脚本就可以启动服务

# 启动 Samba 服务
./stupsmb.sh

# 查看进程是否运行
ps aux | grep smbd

效果

一下子多了200多G空间，应该足够坚持到过保咯。

挂在效果
