1. updog 简述
updog，一个基于python的云盘环境搭建工具，可以帮助我们在服务器上搭建类似云盘的服务，使得我们可以在web界面中完成文件的上传与下载，十分的方便。
2. updog 安装
在命令行执行下面命令安装updog，注意必须基于 python3.x 进行安装

3. updog 配置服务
cd ~/
mkdir updog
cd updog
updog -p 9090 --password 123456执行updog命令后如下所示
[+] Serving /home/luckynote/updog… * Running on
http://0.0.0.0:9090/ (Press CTRL+C to quit)
此时即可点击链接打开网页，登陆密码按照设定的密码，用户名为空
登陆后即可完成上传下载的任务
4. updog 命令参数说明
updog -d DIRECTORY -p PORT --password PASSWORD其中参数d表示服务开启的根目录，即在服务开启后访问服务无法查看此目录同级别或以上的目录，默认为当前目录；
参数p表示服务开启的端口，默认9090；
参数password表示密码，使用HTTP basic authentication来进行密码保护，无用户名，默认无密码，即直接可以访问，当然这种不建议。
5. updog 补充
在关闭命令终端后，updog服务将自动关闭，这时候我们需要将另外一条命令来挂起updog
nohup updog -p 9091 --password 123456 &这时候云盘路径下多了 nohub.out 文件，此时，我们的服务便在后台挂起，即便关闭终端也可以正常访问云盘服务。
而如果想要关闭之前在后台挂起的服务，可以先通过
fuser -v -n tcp 端口号来查找对应的程序ID，然后使用kill -s 9 程序ID来关闭指定服务。
【PS】当然除了使用 nohub ，也可以使用 screen命令挂起服务，具体的命令这里就不多做介绍了，感兴趣的小伙伴可以自己查找 screen 的命令说明。
6. updog 好处
- 操作简单，仅仅需要几步就能让你拥有一个自主的网盘终端
- 非常适用于局域网内搭建统一管理的网盘系统
- 一台服务器可以开启多个不同配置的updog服务
