继续折腾 NanoPC-T4之 私有云部署

Posted 2022-07-28 bywayboy

前言

自从360 等各大云盘开始收费， 莆田系各种恶心限速以来，一直想搭建一个自己的私有云服务器。以满足手机/PC等个机器之间的文件同步（中间用GIT替代过一段时间）. 虽然强大 但各种不方便。在尝试了 seafile、owncloud等后，发现这些东东都不能满足在树莓派嵌入式单板机器上的使用要求。于是转而寻求一个适合嵌入式机器使用的私有云软件。syncthing 出现了。

经过一段时间的折腾测试。目前已经成功部署且工作良好。

syncthing 总共分为三个组件。

1. syncthing 同步软件 用于文件夹变动监视、同步。
2. stdiscosrv 发现服务器 用户各机器之间发现对方。
3. strelaysrv 中转服务器 针对一些特殊网络环境无公网IP的宽带。或者路由器不止UPNP映射的环境通过 relay服务器中转同步

接下来一步步部署这三个软件

部署

还是直接整理成安装脚本吧. 方便大家直接使用

#!/bin/bash
arch=$(dpkg --print-architecture)
