1. updog 簡述
updog，一個基於python的雲盤環境搭建工具，可以幫助我們在服務器上搭建類似雲盤的服務，使得我們可以在web界面中完成文件的上傳與下載，十分的方便。
2. updog 安裝
在命令行執行下面命令安裝updog，注意必須基於 python3.x 進行安裝
pip3 install updog

3. updog 配置服務
cd ~/
mkdir updog
cd updog
updog -p 9090 --password 123456
執行updog命令後如下所示
[+] Serving /home/luckynote/updog… * Running on
http://0.0.0.0:9090/ (Press CTRL+C to quit)
此時即可點擊鏈接打開網頁，登陸密碼按照設定的密碼，用戶名爲空
登陸後即可完成上傳下載的任務
4. updog 命令參數說明
updog -d DIRECTORY -p PORT --password PASSWORD
其中參數d表示服務開啓的根目錄，即在服務開啓後訪問服務無法查看此目錄同級別或以上的目錄，默認爲當前目錄；
參數p表示服務開啓的端口，默認9090；
參數password表示密碼，使用HTTP basic authentication來進行密碼保護，無用戶名，默認無密碼，即直接可以訪問，當然這種不建議。
5. updog 補充
在關閉命令終端後，updog服務將自動關閉，這時候我們需要將另外一條命令來掛起updog
nohup updog -p 9091 --password 123456 &
這時候雲盤路徑下多了 nohub.out 文件，此時，我們的服務便在後臺掛起，即便關閉終端也可以正常訪問雲盤服務。
而如果想要關閉之前在後臺掛起的服務，可以先通過
fuser -v -n tcp 端口號
來查找對應的程序ID，然後使用kill -s 9 程序ID來關閉指定服務。
【PS】當然除了使用 nohub ，也可以使用 screen命令掛起服務，具體的命令這裏就不多做介紹了，感興趣的小夥伴可以自己查找 screen 的命令說明。
6. updog 好處
- 操作簡單，僅僅需要幾步就能讓你擁有一個自主的網盤終端
- 非常適用於局域網內搭建統一管理的網盤系統
- 一臺服務器可以開啓多個不同配置的updog服務
