Problem Description: When configuring the Subsonic server using the config file /etc/default/subsonic, none of the environment variables SUBSONIC_HOME, SUBSONIC_HOST, SUBSONIC_PORT etc. that are supposed to be used are honored - it just falls back to the default values set in subsonic.sh. The only variable that seems to make it from that config file to the actual execution is SUBSONIC_ARGS.
Troubleshooting Steps: I set these variables in an attempt to configure my server in a way that wouldn't be overwritten by an upgrade.
Contents of /etc/default/subsonic (comments removed) below:
- Code: Select all
SUBSONIC_ARGS="--max-memory=150"
SUBSONIC_CONTEXT_PATH=/music
SUBSONIC_HOST=localhost
This resulted in a command line like the following, clearly not honoring my SUBSONIC_HOST and SUBSONIC_CONTEXT_PATH settings:
- Code: Select all
java -Xmx150m -Dsubsonic.home=/var/subsonic -Dsubsonic.host=0.0.0.0 -Dsubsonic.port=4040 -Dsubsonic.httpsPort=0 -Dsubsonic.contextPath=/ -Dsubsonic.db= -Dsubsonic.defaultMusicFolder=/var/music -Dsubsonic.defaultPodcastFolder=/var/music/Podcast -Dsubsonic.defaultPlaylistFolder=/var/playlists -Djava.awt.headless=true -verbose:gc -jar subsonic-booter-jar-with-dependencies.jar
However, if I put the configuration parameters into the SUBSONIC_ARGS string to be parsed as command line arguments (SUBSONIC_ARGS="--max-memory=150 --host=localhost --context-path=/music") everything works like it should:
- Code: Select all
java -Xmx150m -Dsubsonic.home=/var/subsonic -Dsubsonic.host=localhost -Dsubsonic.port=4040 -Dsubsonic.httpsPort=0 -Dsubsonic.contextPath=/music -Dsubsonic.db= -Dsubsonic.defaultMusicFolder=/var/music -Dsubsonic.defaultPodcastFolder=/var/music/Podcast -Dsubsonic.defaultPlaylistFolder=/var/playlists -Djava.awt.headless=true -verbose:gc -jar subsonic-booter-jar-with-dependencies.jar

<-------------------------Subsonic Help Request---------------------->
I might add that the same config file (/etc/default/subsonic) worked with subsonic server 6.0 but has been broken with every 6.1.* version.
The install was done using the debian package and I'm using Apache 2.4 as a frontend proxy with subsonic listening on localhost only, so this bug broke my setup as it immediately redirected me to localhost:4040 when attempting to log in via the browser.
