Subsonic Forum

Hi folks,

I struggled with running my Subsonic installation with Apple's LaunchDaemon. LaunchDaemon starts Subsonic as root at system startup. Here's how i did.

Step 1: Download Subsonic standalone version and put contents in "/opt/local/subonic" (be careful with rights: folder and files should have "755 root admin").

Step 2: Edit "/opt/local/subsonic/subsonic.sh" to set the startup variables.

Code: Select all

SUBSONIC_HOME=/opt/local/var/subsonic
SUBSONIC_HOST=0.0.0.0
SUBSONIC_PORT=4040
SUBSONIC_HTTPS_PORT=0
SUBSONIC_CONTEXT_PATH=/
SUBSONIC_MAX_MEMORY=200
SUBSONIC_PIDFILE=
SUBSONIC_DEFAULT_MUSIC_FOLDER=/path/to/music
SUBSONIC_DEFAULT_PODCAST_FOLDER=/path/to/podcasts
SUBSONIC_DEFAULT_PLAYLIST_FOLDER=/path/to/playlists

Step 3: Start Subsonic once with the startup script to ensure that all folders exist: "sh /opt/local/subsonic/subsonic.sh".

Step 4: Create LaunchDaemon ParameterList in "/Library/LaunchDaemons/org.subsonic.plist" with rights "755 root wheel".

Code: Select all

        <key>Disabled</key><false/>
        <key>OnDemand</key><false/>
        <key>RunAtLoad</key><true/>
</dict>
</plist>

Step 5: Reboot and check if subsonic started without problems (have a look at "/opt/local/var/subsonic/subsonic.log").

Improvement suggestions are welcome.

Good luck!

Thanks for this. Works great.

Why would you want to run Subsonic as root? Sounds like an security risk with no benefit.

Because LaunchDaemon needs root afaik.

Yes, but you could instead make it a LaunchAgent with a normal user. Or simply add Subsonic.app to Login Items in the GUI. I just don't see the benefit of using a LaunchDaemon.

Placing the App in login items needs a logged in user. With LaunchDeamon Subsonic will start, even if my server crashes and reboots (I disable automatic login by default > security). It is safer to run Subsonic as root than to configure a server to automatically log in on start.

I'm surprised you can't do both... I'm a windows users, and I can create a service that runs under a non-administrative account for subsonic. Is that not possible on a mac?

Yes, but you can specify which user you want the daemon to run as:-


UserName <string>
This optional key specifies the user to run the job as. This key is only applicable when launchd is
running as root.

GroupName <string>
This optional key specifies the group to run the job as. This key is only applicable when launchd is
running as root. If UserName is set and GroupName is not, the the group will be set to the default
group of the user.
