## Requirements
- Go 1.12 or higher.
- Go 1.12 or higher as build only dependency.
- A suitable SQL server or key/value store to use as data provider: PostreSQL 9.4+ or MySQL 5.6+ or SQLite 3.x or bbolt 1.3.x
## Installation
Simple install the package to your [$GOPATH](https://github.com/golang/go/wiki/GOPATH "GOPATH") with the [go tool](https://golang.org/cmd/go/ "go command") from shell:
Binary releases for Linux, macOS and Windows are available, please visit the [releases](https://github.com/drakkan/sftpgo/releases "releases") page.
Sample Dockerfiles for [Debian](https://www.debian.org "Debian") and [Alpine](https://alpinelinux.org "Alpine") are available inside the source tree [docker](./docker "docker") directory.
Alternately you can install the package to your [$GOPATH](https://github.com/golang/go/wiki/GOPATH "GOPATH") with the [go tool](https://golang.org/cmd/go/ "go command") from shell:
```
$ go get -u github.com/drakkan/sftpgo

Make sure [Git](https://git-scm.com/downloads) is installed on your machine and in your system's `PATH`.
SFTPGo depends on [go-sqlite3](https://github.com/mattn/go-sqlite3) that is a CGO package and so it requires a `C` compiler at build time.
On Linux and macOS a compiler is easy to install or already installed, on Windows you need to download [MinGW-w64](https://sourceforge.net/projects/mingw-w64/files/) and build SFTPGo from its command prompt.

## REST API
SFTPGo exposes REST API to manage users and quota and to get real time reports for the active connections with possibility of forcibly closing a connection.
SFTPGo exposes REST API to manage users and quota, to backup and restore users and to get real time reports for the active connections with possibility of forcibly closing a connection.
If quota tracking is enabled in `sftpgo` configuration file, then the used size and number of files are updated each time a file is added/removed. If files are added/removed not using SFTP or if you change `track_quota` from `2` to `1`, you can rescan the user home dir and update the used quota using the REST API.
