## Installation
|
|
|
|
_Supysonic_ can run as a standalone application (not recommended for a
|
|
"production" server) or as a WSGI application (on _Apache_ for instance).
|
|
|
|
To install it, either run:
|
|
|
|
$ python setup.py install
|
|
|
|
or
|
|
|
|
$ pip install .
|
|
|
|
but not both.
|
|
|
|
### Prerequisites
|
|
|
|
You'll need these to run _Supysonic_:
|
|
|
|
* Python >= 3.5
|
|
* [Flask](http://flask.pocoo.org/)
|
|
* [PonyORM](https://ponyorm.com/)
|
|
* [Python Imaging Library](https://github.com/python-pillow/Pillow)
|
|
* [requests](http://docs.python-requests.org/)
|
|
* [mutagen](https://mutagen.readthedocs.io/en/latest/)
|
|
* [watchdog](https://github.com/gorakhargosh/watchdog)
|
|
* [zipstream](https://github.com/allanlei/python-zipstream)
|
|
|
|
All the dependencies will automatically be installed by the
|
|
installation command above.
|
|
|
|
You may also need a database specific package if you don't want to use SQLite
|
|
(the default):
|
|
|
|
* _MySQL_: `pip install pymysql` or `pip install mysqlclient`
|
|
* _PostgreSQL_: `pip install psycopg2-binary`
|
|
|
|
### Database initialization
|
|
|
|
_Supysonic_ needs a database to run. It can either be a _SQLite_,
|
|
_MySQL_-compatible or _PostgreSQL_ database.
|
|
|
|
Please refer to the documentation of the DBMS you've chosen on how to create a
|
|
database. Once it has a database, _Supysonic_ will automatically create the
|
|
tables it needs.
|
|
|
|
If you want to use _PostgreSQL_ you'll have to add the `citext` extension to the
|
|
database once created. This can be done when connected to the database as the
|
|
superuser with the folowing SQL command:
|
|
|
|
supysonic=# CREATE EXTENSION citext;
|
|
|
|
If you absolutely have no clue about databases, you can go with _SQLite_ as it
|
|
doesn't need any setup other than specifying a path for the database.
|
|
Note that using _SQLite_ for large libraries might not be the brightest idea as
|
|
it tends to struggle with larger datasets.
|
|
|
|
### Configuration
|
|
|
|
Once you have a database, you'll need to create a configuration file. It must
|
|
be saved under one of the following paths:
|
|
|
|
* `/etc/supysonic`
|
|
* `~/.supysonic`
|
|
* `~/.config/supysonic/supysonic.conf`
|
|
|
|
A roughly documented sample configuration file is provided as `config.sample`.
|
|
|
|
The minimal configuration using a _SQLite_ database would be:
|
|
|
|
```ini
|
|
[base]
|
|
database_uri = sqlite:////some/path/to/a/supysonic.db
|
|
```
|
|
|
|
For a more details on the configuration, please refer to
|
|
[documentation][docs-config].
|
|
|
|
[docs-config]: docs/configuration.md
|
|
|
|
## Running the application
|
|
|
|
### As a standalone debug server
|
|
|
|
It is possible to run _Supysonic_ as a standalone server, but it is only
|
|
recommended to do so if you are hacking on the source. A standalone won't be
|
|
able to serve more than one request at a time.
|
|
|
|
To start the server, just run the `cgi-bin/server.py` script.
|
|
|
|
$ python cgi-bin/server.py
|
|
|
|
By default, it will listen on the loopback interface (`127.0.0.1`) on port
|
|
5000, but you can specify another address on the command line, for instance on
|
|
all the IPv6 interfaces:
|
|
|
|
$ python cgi-bin/server.py ::
|
|
|
|
### As an _Apache_ WSGI application
|
|
|
|
_Supysonic_ can run as a WSGI application with the `cgi-bin/supysonic.wsgi`
|
|
file. To run it within an _Apache2_ server, first you need to install the WSGI
|
|
module and enable it.
|
|
|
|
$ apt install libapache2-mod-wsgi-py3
|
|
$ a2enmod wsgi
|
|
|
|
Next, edit the _Apache_ configuration to load the application. Here's a basic
|
|
example of what it looks like:
|
|
|
|
WSGIScriptAlias /supysonic /path/to/supysonic/cgi-bin/supysonic.wsgi
|
|
<Directory /path/to/supysonic/cgi-bin>
|
|
WSGIApplicationGroup %{GLOBAL}
|
|
WSGIPassAuthorization On
|
|
Require all granted
|
|
</Directory>
|
|
|
|
With that kind of configuration, the server address will look like
|
|
*http://server/supysonic/*
|
|
|
|
### Other options
|
|
|
|
If you use another HTTP server, such as _nginx_ or _lighttpd_, or prefer to use
|
|
FastCGI or CGI over WSGI, FastCGI and CGI scripts are also provided in the
|
|
`cgi-bin` folder, respectively as `supysonic.fcgi` and `supysonic.cgi`. You
|
|
might need to edit those file to suit your system configuration.
|
|
|
|
Here are some quick docs on how to configure your server for [FastCGI][] or
|
|
[CGI][].

### Docker

|
|
|
If you want to run _Supysonic_ in a _Docker_ container, here are some images
|
|
provided by the community.

|
## Quickstart
|
|
|
|
To start using _Supysonic_, you'll first have to specify where your music
|
|
library is located and create a user to allow calls to the API.
|
|
|
|
Let's start by creating a new admin user this way:
|
|
|
|
$ supysonic-cli user add MyUserName -a -p MyAwesomePassword
|
|
|
|
To add a new folder to your music library, you can do something like this:
|
|
|
|
$ supysonic-cli folder add MyLibrary /home/username/Music
|
|
|
|
Once you've added a folder, you will need to scan it:
|
|
|
|
$ supysonic-cli folder scan MyLibrary
|
|
|
|
You should now be able to enjoy your music with the client of your choice!
|
|
|
|
For more details on the command-line usage, take a look at the
|
|
[documentation][docs-cli].
|
|
|
|
[docs-cli]: docs/cli.md
|
|
|
|
## Client authentication
|
|
|
|
The Subsonic API provides several authentication methods. One of them, known as
|
|
_token authentication_ was added with API version 1.13.0. As Supysonic currently
|
|
targets API version 1.9.0, the token based method isn't supported. So if your
|
|
client offers you the option, you'll have to disable the token based
|
|
authentication for it to work.
|
|
|
|
## Running the daemon
|
|
|
|
_Supysonic_ comes with an optional daemon service that currently provides the
|
|
following features:
|
|
- background scans
|
|
- library changes detection
|
|
|
|
First of all, the daemon allows running backgrounds scans, meaning you can start
|
|
scans from the CLI and do something else while it's scanning (otherwise the scan
|
|
will block the CLI until it's done).
|
|
Background scans also enable the web UI to run scans, while you have to use the
|
|
CLI to do so if you don't run the daemon.
|
|
|
|
Instead of manually running a scan every time your library changes, the daemon
|
|
can listen to any library change and update the database accordingly. This
|
|
watcher is started along with the daemon but can be disabled to only keep
|
|
background scans.
|
|
|
|
The daemon is `supysonic-daemon`, it is a non-exiting process. If you want to
|
|
keep it running in background, either use the old `nohup` or `screen` methods,
|
|
or start it as a _systemd_ unit (see the very basic _supysonic-daemon.service_
|
|
file).
|
|
|
|
## Upgrading
|
|
|
|
To upgrade your _Supysonic_ installation, simply re-run the command you used to
|
|
install it (either `python setup.py install` or `pip install .`).
|
|
|
|
Some commits might introduce changes in the database schema. Starting with
|
|
commit e84459d6278bfc735293edc19b535c62bc2ccd8d (August 29th, 2018) migrations
|
|
will be automatically applied.
|
|
|
|
If your database was created prior to this date, you'll have to manually apply
|
|
unapplied migrations up to the latest. Once done you won't have to worry about
|
|
future migrations as they'll be automatically applied.
|
|
Migration scripts are provided in the `supysonic/schema/migration` folder, named
|
|
by the date of commit that introduced the schema changes. There could be both
|
|
SQL scripts or Python scripts. The Python scripts require arguments that are
|
|
explained when the script is invoked with the `-h` flag.
