I realized shortly after completing this that wintermute already posted a bash-script for starting subsonic. However personally I prefer to have all services running as dedicated users to prevent any security breaches and such on my server. No offense to wintermute
Here's at least how Subsonic is handled by my system, free for anybody to use
Subsonic is started automatically by init at boot time on runlevels 3-5 run as the user subsonic
This is done without modifying the original subsonic.sh at all to avoid having to do updates after upgrading Subsonic
PS: However some changes to subsonic.sh could improve the init-script somewhat
init-script put in /etc/init.d/subsonic
- Code: Select all
#!/bin/sh
#
# chkconfig: 345 99 05
# /etc/init.d/subsonic
#
# Description: Linux startup-script for Subsonic standalone
#
[ ! -d /usr/bin ] && exit
# On RedHat AS 3 and above, use runuser rather than su

To setup the subsonic user and register the init-script
- Code: Select all
sudo adduser subsonic -c "Subsonic Media Streamer" -d /var/subsonic -M -s /sbin/nologin
sudo chown -R subsonic.subsonic /var/subsonic
sudo chmod og+x /etc/init.d/subsonic
sudo chkconfig --add subsonic
Example of usage
- Code: Select all
$ sudo service subsonic
Usage: subsonic {start|stop|status|restart}
$ sudo service subsonic status
Subsonic Media Streamer is not running..
$ sudo service subsonic start
Starting Subsonic Media Streamer: [ OK ]
$ sudo service subsonic status
Subsonic Media Streamer is running.. Found PID 31136
$ sudo service subsonic stop
Stopping Subsonic Media Streamer: [ OK ]
$ sudo service subsonic status
Subsonic Media Streamer is not running..
