Raspbian: automatic restart of minimserver after reboot doesn't work

[catsup]

Fortunately, I managed to solve the java issue (thnx to Simon) on my RPI 2.

In general, minimserver works fine, streams music etc. Great!

However, unfortunately, the automatic restart of minimserver doesn't work.
To avoid any other conflict with the installation attempt and the java issue, I uninstalled minimserver (using the keep config option which led to another issue when re-installing - details as below) and finally re-installed minimserver from scratch. It again works fine except for the automatic restart.

Here are the details:

While uninstalling I have chosen to keep the config file.

During re-installation, this error occurred:
un-taring done before
pi@bwtmusic:~ $ minimserver/bin/setup
mv: der Aufruf von stat für '/home/pi/.minimserver/bin/setup' ist nicht möglich: Datei oder Verzeichnis nicht gefunden
pi@bwtmusic:~ $

So the setup program in .minimserver was not found.
I played arround for a while but figured to throw away e.th. and start from scratch as I doen't have much (config etc.) to loose:

I *believe* s.th. is wrong in /etc/init.d/minimserver, but I am not sure what.

Any help is greatly appreciated.

Thanks

When automatic startup fails, what is in the files minimserver.log and minimserver-out.log in the minimserver/data directory?

It is normal for the /etc/init.d directory to not contain a minimserver-init.sh file amd it is also normal for the /var/log/minimserver-init.log file to have a length of 0 bytes.

Hm, it looks like that the non-default java environment

$ java -version

$ echo $JAVA_HOME
/usr/lib/jvm/zulu11.43.100-ca-jdk11.0.9.1-linux_aarch32hf

is not being picked during boot.

As said, starting MinimServer manually with startd works just fine.

Any idea to fix the - probably - Java environment/path issue?

Thanks a lot!

I suggest you put a symbolic link to the Zulu java executable in the /usr/local/bin directory, as follows:

sudo ln -s /usr/lib/jvm/zulu11.43.100-ca-jdk11.0.9.1-linux_aarch32hf/bin/java /usr/local/bin

If you do this, you can remove your custom setting for PATH.

Edit: added sudo to the command.

Hi Simon,

thanks, this workaround worked!

MinimServer now is starting after reboot.

Thanks
catsup

P.S.: the symlink command has to be performed with sudo.

I'm glad to hear this is all working now. I have edited my previous post to add sudo.
