service wrapper broken

service wrapper broken

[dvanherbergen]

Which OS are you using? Are you running on an ARMv6/v7 machine?

[dakky]

Running on raspberry pi2 with raspbian jessie

[dvanherbergen]

Can you execute the command arch and post the result?

[dakky]

armv7l

[dvanherbergen]

Strange. We know there is an issue with the service on armv6, but on v7 it should work.
I don't have a pi2 myself, so I can't really test. The openHAB service is using the karaf service installation underneath. Could you try downloading karaf and installing that as a service by executing the command 'wrapper:install' in the shell?

@kaikreuzer did you test starting the service on your pi2?

@kaikreuzer did you test starting the service on your pi2?

No, not yet.

same problem when creating a service:

Hit '<ctrl-d>' or type 'system:shutdown' or 'logout' to shutdown Karaf.

Setup complete.  You may wish to tweak the JVM properties in the wrapper configuration file:
    /tmp/apache-karaf-4.0.3/etc/karaf-wrapper.conf
before installing and starting the service.

That's bad news. That means that the Java Service Wrapper which is included in Karaf doesn't work. And because of a license change, it won't be upgraded anymore.
So we'll have to rework the whole service installation part 😞
This will take some time...

[dakky]

an alternative might be, to work around problem and do not use the karaf native service. in openhab 1.x (pre "there are some deb packages,too"-phase) I had a hacky solution.
starting openhab:

sudo -u ${OHUSER} tmux new-session -s openHAB -d  "sh ./start.sh"

stopping openhab:

sudo -u ${OHUSER} tmux send-keys -t openHAB "exit" Enter "y" Enter "exit" Enter

not very beautyful, but it worked. Creds for this solution to "I don't know where i digged this up"

[kaikreuzer]

Hm, this is really unfortunate, I was so happy that Karaf offered this service and no it is irrepairably broken :-(

So maybe we need to implement our own logic to generated the required files (at least on the platform, where the Karaf solution does not work). Maybe this would be a start for it: https://community.openhab.org/t/start-script-for-oh2/5883/7?u=kai

[dakky]

https://issues.apache.org/jira/browse/KARAF-2734 unresolved :(

[dakky]

have a look here: https://community.openhab.org/t/start-script-for-oh2/5883/15

starting the start.sh via systemd works fine. so there is no need for the karaf service wrapper on any systemd enabled distributions.

[kaikreuzer]

Since the service wrapper does not work for RaspPi, this has been solved through documentation now: https://github.com/openhab/openhab-distro/pull/74/files
