SGFS

Simple Golang File Server

SGFS, a open source file server, implement by golang that can be used to upload and download files. Simple to deploy, simple to use.

Advantage

• SGFS is easy to configure and deploy. (use yaml config and have no runtime dependencies)

• SGFS is easy to start and stop. (use ./startup.sh to start and use ./shutdown.sh to stop)

• SGFS is easy to use. (use HTTP to upload and delete file)

• SGFS use fasthttp to implement. (strong ability to deal with concurrent problems and fast speed. [https://github.com/valyala/fasthttp])

Quick Start

• Download release version.
  https://github.com/LinkinStars/sgfs/releases

• Configure conf.yml .
  (You don't have to configure it, but you'd better have a look.)

• Start server

  $ ./startup.sh
  

• Test to upload file
  I use postman to test and you can use any other methods(by HTTP).
  The default url is http://127.0.0.1:9001/upload-file If the response json have code and the code is 1, Congratulations, the file upload success. If not, you can follow the message to fix the problem.

• Visit file
  http://127.0.0.1:9002/pic/2019-02-22/20190222151902_7848902316.jpg
  If you set conf.yml generate_index_pages is true, you can visit the index page.
  http://127.0.0.1:9002/

• Delete file
  

• Stop server

  $ ./shutdown.sh
  

PS: Note that the default file operation port is 9001, and the default file access port is 9002, which is different.

HTTP

About Update

2. If you modify the conf.yml about old version please backup it before update.
3. Download release version and decompression to update. Easy.

• remove startup and shutdown scripts
• add cli commands to start server and shutdown
