# Configuration
|
|
|
|
_Supysonic_ looks for four files for its configuration: `/etc/supysonic`,
|
|
`~/.supysonic`, `~/.config/supysonic/supysonic.conf` and `supysonic.conf` in
|
|
the current folder, merging values from all files.
|
|
|
|
Configuration files must respect a structure similar to Windows INI file, with
|
|
`[section]` headers and using a `KEY = VALUE` or `KEY: VALUE` syntax.
|
|
|
|
You'll find a roughly documented configuration sample file at the root of the
|
|
project, file conveniently named `config.sample`. More details below.
|
|
|
|
There are six sections in the configuration:
|
|
- [base](#base-section): defines the database and additional scanning config
|
|
- [webapp](#webapp-section): configuration relative to the HTTP server
|
|
- [daemon](#daemon-section): configuration for the scanning file watcher
|
|
- [lastfm](#lastfm-section): keys to enable Last.FM scrobbling
|
|
- [transcoding](#transcoding-section): defines transcoding programs
|
|
- [mimetypes](#mimetypes-section): some file extension to mimetype mappings
|
|
|
|
## `[base]` section
|
|
|
|
`database_uri`: the most important configuration, defines the type and
|
|
parameters of the database _Supysonic_ should connect to. It usually includes
|
|
username, password, hostname and database name. The typical form of a database
|
|
URI is:
|
|
|
|
driver://username:password@host:port/database
|
|
|
|
If the connection needs some additional parameters, they can be provided as a
|
|
query string, such as:
|
|
|
|
driver://username:password@host:port/database?param1=value1¶m2=value2
|
|
|
|
Supported drivers are `sqlite`, `mysql` and `postgres` (or `postgresql`).
|
|
|
|
As SQLite connects to local files, the format is slightly different. The "file"
|
|
portion of the URI is the filename of the database. For a relative path, it
|
|
requires three slashes, for absolute paths it's also three slashes followed by
|
|
the absolute path, meaning actually four slashes on Unix systems.
|
|
|
|
```ini
|
|
; Relative path
|
|
database_uri = sqlite:///relative-file.db
|
|
; Absolute path on Unix-based systems
|
|
database_uri = sqlite:////home/user/supysonic.db
|
|
; Absolute path on Windows
|
|
database_uri = sqlite:///C:\Users\user\supysonic.db
|
|
```
|
|
|
|
A MySQL-compatible database requires either `MySQLdb` or `pymysql` to be
|
|
installed. PostgreSQL needs `psycopg2`.
|
|
Note that for MySQL if no character set is defined on the URI it defaults to
|
|
`utf8mb4` regardless of what's set on your MySQL installation.
|
|
|
|
If `database_uri` isn't provided, it defaults to a SQLite database stored in
|
|
`/tmp/supysonic/supysonic.db`.
|
|
|
|
`scanner_extensions`: A space separated list of file extensions the scanner is
|
|
restricted to. Useful if you have multiple audio formats in your library but
|
|
only want to serve some. If left empty, the scanner will try to read every file
|
|
it finds.
|
|
|
|
`follow_symlinks`: if set to `yes`, allows the scanner to follow symbolic links.
|
|
Disabled by default, enable it only if you trust your file system as nothing is
|
|
done to handle broken links or loops.
|
|
|
|
```ini
|
|
[base]
|
|
; A database URI. See the 'schema' folder for schema creation scripts
|
|
; Default: sqlite:////tmp/supysonic/supysonic.db
|
|
database_uri = sqlite:////var/supysonic/supysonic.db
|
|
;database_uri = mysql://supysonic:supysonic@localhost/supysonic
|
|
;database_uri = postgres://supysonic:supysonic@localhost/supysonic
|
|
|
|
; Optional, restrict scanner to these extensions. Default: none
|
|
scanner_extensions = mp3 ogg
|
|
|
|
; Should the scanner follow symbolic links? Default: no
|
|
follow_symlinks = no
|
|
```
|
|
|
|
## `[webapp]` section
|
|
|
|
`cache_dir`: directory used to store generated files, such as resized cover
|
|
art or transcoded files. Defaults to `/tmp/supysonic`.
|
|
|
|
`cache_size`: maximum size (in megabytes) of the cache (except for trancodes).
|
|
Defaults to 512 MB
|
|
|
|
`transcode_cache_size`: maximum size (in megabytes) of the transcode cache.
|
|
Defaults to 1024 MB (1 GB)
|
|
|
|
`log_file`: rotating file where some events generated by the web server are
|
|
logged. Leave empty to disable logging.
|
|
|
|
`log_level`: defines the minimum severity threshold of messages to be added to
|
|
`log_file`. Possible values are: `DEBUG`, `INFO`, `WARNING`, `ERROR` and
|
|
`CRITICAL`. Defaults to `WARNING`.
|
|
|
|
`mount_api`: [`on`/`off`] enable or disable the Subsonic REST API. Should be
|
|
kept on or _Supysonic_ would be quite useless. Exists mostly for testing
|
|
purposes. Defaults to `on`.
|
|
|
|
`mount_webui`: [`on`/`off`] enable or disable the administrative web interface.
|
|
Note that setting this off will prevent users from defining a preferred
|
|
transcoding format. Defaults to `on`.
|
|
|
|
```ini
|
|
[webapp]
|
|
; Optional cache directory. Default: /tmp/supysonic
|
|
cache_dir = /var/supysonic/cache
|
|
|
|
; Main cache max size in MB. Default: 512
|
|
cache_size = 512
|
|
|
|
; Transcode cache max size in MB. Default: 1024 (1GB)
|
|
transcode_cache_size = 1024
|
|
|
|
; Optional rotating log file. Default: none
|
|
log_file = /var/supysonic/supysonic.log
|
|
|
|
; Log level. Possible values: DEBUG, INFO, WARNING, ERROR, CRITICAL.
|
|
; Default: WARNING
|
|
log_level = WARNING
|
|
|
|
; Enable the Subsonic REST API. You'll most likely want to keep this on.
|
|
; Here for testing purposes. Default: on
|
|
;mount_api = on
|
|
|
|
; Enable the administrative web interface. Default: on
|
|
;mount_webui = on
|
|
```
|
|
|
|
## `[daemon]` section
|
|
|
|
`socket`: Unix domain socket file (or named pipe on Windows) used to communicate
|
|
between the daemon and clients that rely on it (eg. CLI, folder admin web page,
|
|
etc.). Note that using an IP address here isn't supported.
|
|
Default: /tmp/supysonic/supysonic.sock
|
|
|
|
`run_watcher`: whether or not to start the watcher that will listen for library
|
|
changes. Default: yes
|
|
|
|
`wait_delay`: delay before triggering the scanning operation after a change
|
|
have been detected. This prevents running too many scans when multiple changes
|
|
are detected for a single file over a short time span. Default: 5 seconds.
|
|
|
|
`log_file`: rotating file where events generated by the file watcher are logged.
|
|
If left empty, any logging will be sent to stderr.
|
|
|
|
`log_level`: defines the minimum severity threshold of messages to be added to
|
|
`log_file`. Possible values are: `DEBUG`, `INFO`, `WARNING`, `ERROR` and
|
|
`CRITICAL`. Defaults to `WARNING`.
|
|
|
|
```ini
|
|
[daemon]
|
|
; Socket file the daemon will listen on for incoming management commands
|
|
; Default: /tmp/supysonic/supysonic.sock
|
|
socket = /var/run/supysonic.sock
|
|
|
|
; Defines if the file watcher should be started. Default: yes
|
|
run_watcher = yes
|
|
|
|
; Delay before triggering scanning operation after a change have been detected
|
|
; This prevents running too many scans when multiple changes are detected for a
|
|
; single file over a short time span. Default: 5
|
|
wait_delay = 5
|
|
|
|
; Optional rotating log file for the scanner daemon. Logs to stderr if empty
|
|
log_file = /var/supysonic/supysonic-daemon.log
|
|
log_level = INFO
|
|
```
|
|
|
|
## `[lastfm]` section
|
|
|
|
This section allow defining API keys to enable Last.FM integration in
|
|
_Supysonic_. Currently it is only used to _scrobble_ played tracks and update
|
|
the _now playing_ information.
|
|
See https://www.last.fm/api to obtain such keys.
|
|
Once keys are set, users have to link their account by visiting their profile
|
|
page on _Supysonic_'s administrative UI.
|
|
|
|
`api_key`: Last.FM API key
|
|
|
|
`secret`: secret key associated to the API key
|
|
|
|
```ini
|
|
[lastfm]
|
|
; API and secret key to enable scrobbling. http://www.last.fm/api/accounts
|
|
; Defaults: none
|
|
;api_key =
|
|
;secret =
|
|
```
|
|
|
|
## `[transcoding]` section
|
|
|
|
This section defines command-line programs to be used to convert an audio file
|
|
to another format or change its bitrate. All configurations in the sample below
|
|
have **not** been thoroughly tested.
|
|
For more details, please refer to the
|
|
[transcoding configuration](transcoding.md).
|
|
|
|
```ini
|
|
[transcoding]
|
|
; Programs used to convert from one format/bitrate to another. Defaults: none
|
|
transcoder_mp3_mp3 = lame --quiet --mp3input -b %outrate %srcpath -
|
|
transcoder = ffmpeg -i %srcpath -ab %outratek -v 0 -f %outfmt -
|
|
decoder_mp3 = mpg123 --quiet -w - %srcpath
|
|
decoder_ogg = oggdec -o %srcpath
|
|
decoder_flac = flac -d -c -s %srcpath
|
|
encoder_mp3 = lame --quiet -b %outrate - -
|
|
encoder_ogg = oggenc2 -q -M %outrate -
|
|
```
|
|
|
|
## `[mimetypes]` section
|
|
|
|
Use this section if the system _Supysonic_ is installed on has trouble guessing
|
|
the mimetype of some files. This might only be useful in some rare cases.
|
|
|
|
See the following links for a list of examples:
|
|
* https://en.wikipedia.org/wiki/Media_type#Common_examples
|
|
* https://www.iana.org/assignments/media-types/media-types.xhtml
|
|
|
|
```ini
|
|
[mimetypes]
|
|
; Extension to mimetype mappings in case your system has some trouble guessing
|
|
; Default: none
|
|
;mp3 = audio/mpeg
|
|
;ogg = audio/vorbis
|
|
```
