## 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, run:
|
|
|
|
$ python setup.py install
|
|
|
|
### Prerequisites
|
|
|
|
You'll need these to run _Supysonic_:
|
|
|
|
* Python 2.7 or >= 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) (if you want to use the
|
|
[watcher](#watching-library-changes))
|
|
|
|
You can install all of them using `pip`:
|
|
|
|
$ pip install .
|
|
|
|
You may also need a database specific package:
|
|
|
|
* _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.
|
|
|
|
_Supysonic_ does not automatically create the database and tables it needs to
|
|
work. Thus the database and tables must be created prior to running the
|
|
application. Please refer to the documentation of the DBMS you've chosen on how
|
|
to create a database and how to use a command-line client. 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;
|
|
|
|
Table creation scripts are provided in the `schema` folder for _SQLite_,
|
|
_MySQL_ and _PostgreSQL_. Just feed them to any client you're able to use.
|
|
|
|
If you absolutely have no clue about databases, you can go with _SQLite_.
|
|
You'll just need the `sqlite3` command-line tool. Install it and create the
|
|
database and tables with the following commands:
|
|
|
|
$ apt install sqlite3
|
|
$ sqlite3 /some/path/to/a/supysonic.db < schema/sqlite.sql
|
|
|
|
Remember the path you've used for the database file
|
|
(`/some/path/to/a/supysonic.db` in the example above), you'll need it in the
|
|
configuration file.
|
|
|
|
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 the _SQLite_ database created on the example
|
|
above whould 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
|
|
$ 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
|
|
Order deny,allow
|
|
Allow from all
|
|
</Directory>
|
|
|
|
You might also need to run _Apache_ using the system default locale, as the one
|
|
it uses might cause problems while scanning the library from the web UI. To do
|
|
so, edit the `/etc/apache2/envvars` file, comment the line `export LANG=C` and
|
|
uncomment the `. /etc/default/locale` line. Then you can restart _Apache_:
|
|
|
|
$ systemctl restart apache2
|
|
|
|
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][].

|
## 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
|
|
|
|
## Watching library changes
|
|
|
|
Instead of manually running a scan every time your library changes, you can run
|
|
a watcher that will listen to any library change and update the database
|
|
accordingly.
|
|
|
|
The watcher is `bin/supysonic-watcher`, it is a non-exiting process and doesn't
|
|
print anything to the console. If you want to keep it running in background,
|
|
either use the old `nohup` or `screen` methods, or start it as a simple
|
|
_systemd_ unit (unit file not included).
|
|
|
|
It needs some additional dependencies which can be installed with the following
|
|
command:
|
|
|
|
$ pip install -e .[watcher]
|
|
|
|
## Upgrading
|
|
|
|
Some commits might introduce changes in the database schema. When that's the
|
|
case migration scripts will be provided in the `schema/migration` folder,
|
|
prefixed by the date of commit that introduced the changes. Those scripts
|
|
shouldn't be used when initializing a new database, only when upgrading from a
|
|
previous schema.
|
|
|
|
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.
|
|
If a migration script isn't provided for a specific database engine, it simply
|
|
means that no migration is needed for this engine.
