Startup Script

[warllo]

Hi,

I installed Subsonic in a jail.

The command to run subsonic is /var/subsonic/subsonic.sh.

I would like to have this command run when the jail is started, I am new to freenas/freebsd and can not figure this out. I have tried adding the command to the /etc/rc.local file however this does not work.

Any suggestions? I am using the command in the /etc/rc.local method for running another application within a different jail under the old UI within warden and it works great however I am not trying to do this in the 11.2 Beta.

Thanks in advance for any input.

If using iocage for the new jail, try iocage exec JAILNAME /var/subsonic/subsonic.sh
this way you can setup the post init command in FreeNAS from the GUI.... Not sure if that will work as teh jail may not be up yet...
Note: This will run as root inside the jail.

Anyone else know off the top of their heads? I need to get lunch and may test when I get back.

The command you listed worked great, it even started the jail that was not running. Where would you set the post init command in the freenas gui?

Its under Tasks. As mentioned use post init but this may still be too early in the boot process. If your feeling ambitious, you could test and report back! :D

Unfortunately this doesn't work when configured under tasks. I'm guessing the Post Init occurs before the jail is started. Why it will start the jail when you run the command manually and not when it's a task is a mystery.

I though that might be an issue.
When you are talking about rc.local, are you referring to inside the jail or the base system? You should still be able to do that inside the jail. Is the subsonic.sh a full service wrapper? perhaps we can symlink it into /etc/rc.d/subsonic and then just add subsonic_enable=yes (I forget the exact syntax for it but that's the idea

I was trying to do this all from within the jail. I don't think it's a full wrapper.

This actually works to start subsonic once the jail has started. It needs some cleanup but it does indeed work.

Code:

#!/bin/sh

# PROVIDE: myscript

. /etc/rc.subr

name="myscript"
rcvar=`set_rcvar`
start_cmd="myscript_start"
stop_cmd=":"

load_rc_config $name

myscript_start()
{
	if checkyesno ${rcvar}; then
	  echo "Starting Subsonic"
   export
PATH=$PATH:/sbin:/bin:/usr/sbin:/usr/bin:/usr/games:/usr/local/sbin:/usr/local/bin:/root/bin
   cd /var/subsonic/
   sh subsonic.sh

	fi
}

run_rc_command "$1"

Quick and dirty. Just the way all RC scripts should be!
