Gotify

#lang-go 

Gotify is a self-hosted push notification service written in Go and distributed under the MIT License. It consists of a server for sending and receiving messages in real-time per WebSocket which is distributed as a single binary. It can be accessed via the built-in web-UI, the cli or the Android app (available via F-Droid and GooglePlay ).

Note

For this guide you should be familiar with the basic concepts of

• supervisord

• domains

• MySQL (optional)

Prerequisites

Gotify comes with a built-in sqlite database, but if you prefer to use MySQL, you can do so.

Gotify can run under a subdomain (e.g. https://gotify.isabella.uber.space) or via a subpath (e.g. https://isabella.uber.space/gotify/).

For both options you need to configure a web backend. The subpath option looks like this:

[isabell@stardust ~]$ uberspace web backend set /gotify/ --http --port 52111 --remove-prefix
Set backend for / to port 52111; please make sure something is listening!
You can always check the status of your backend using "uberspace web backend list".
[isabell@stardust ~]$

Note the –remove-prefix option here. Without it, gotify will not work behind a sub path (e.g. isabell.uber.space/gotify/).

Installation

Like a lot of Go software, gotify is distributed as a single binary. Since version 2.1.7 gotify requires GLIBC 2.28, which is not available in U7. Thus we need to build gotify from source. The building is done as is described in gotify’s documentation but building without docker and only for one architecture:

Warning

The yarn build command may fail at first with an code: 'EPIPE', syscall: 'write' error message. Just run it again until you get Done in 60.48s..

[isabell@stardust ~]$ git clone https://github.com/gotify/server.git

Configuration

Config file

Without configuration, gotify will listen on port 80. To change that to our previously chosen 52111, we will use an environment variable. It is also possible to use a config file, but we will ignore that for now. If you still want to change values in the config, download the example config and adjust it to your needs:

[isabell@stardust gotify]$ wget -O config.yml https://raw.githubusercontent.com/gotify/server/master/config.example.yml
[isabell@stardust gotify]$

Documentation for the config file can be found on the gotify website.

Setup daemon

Create ~/etc/services.d/gotify.ini with the following content.

[program:gotify]
command=%(ENV_HOME)s/gotify/gotify-linux-amd64
directory=%(ENV_HOME)s/gotify/
environment=GOTIFY_SERVER_PORT=52111

After creating the configuration, tell supervisord to refresh its configuration and start the service:

[isabell@stardust ~]$ supervisorctl reread
SERVICE: available
[isabell@stardust ~]$ supervisorctl update
SERVICE: added process group
[isabell@stardust ~]$ supervisorctl status
SERVICE                            RUNNING   pid 26020, uptime 0:03:14
[isabell@stardust ~]$

If it’s not in state RUNNING, check your configuration.

Finishing installation

The default user and password is admin and admin, but you are advised to change in as soon as you log in. You can replace the admin user with an other user with admin privileges later on.

Updates

Note

Check the update feed regularly to stay informed about the newest version.

Check gotify’s releases for the latest version. If a newer version is available, stop daemon by supervisorctl stop gotify and repeat the “Installation” step followed by supervisorctl start gotify to restart gotify.
