Re: AW: CentOS 7/systemd startup script for fuseki
Maybe the best way to proceed is to put a script in now so it gets
picked up in the next release and not worry too much about the details
but instead mark it "experimental" or "template to start from".
We can discuss details we know about but often its the things other
users have in their systems that generate concerns we can not know.
Great tutorial!

The
Environment=FUSEKI_HOME=/opt/fuseki
Environment=FUSEKI_BASE=/etc/fuseki
lines in Osmas script makes the environment settings quite clear. However, I'm
not sure if these completely override the settings in /etc/default/fuseki.
Setting FUSEKI_HOME and FUSEKI_BASE should work.
If /etc/default/fuseki is leaking through that's a bug.
Or we ough to advise not having /etc/default/fuseki and put the setting
in the script.
FUSEKI_HOME and FUSEKI_BASE defaults are supposed to be something simple
and not prescriptive.
The path in
ExecStart=/opt/fuseki/fuseki-server
unfortunately cannot be replaced by $FUSEKI_HOME ("Executable path is not absolute" -
"Refusing").
If published as part of the docs, the memory setting should probably be
Environment=JVM_ARGS=-Xmx2G
perhaps with a hint on how it should increase with total memory size.
Another sentence in
https://jena.apache.org/documentation/fuseki2/fuseki-run.html#fuseki-service could
clarify: "For newer systemd based Linux systems, the script 'fuseki.service' is
provided. Please adapt to your paths and settings."

I think it would be worth including - after some consideration perhaps.
There is already an old-style sysv init script in the Fuseki distribution after
all.
However, I would like some discussion first about what the proper way is to
install Fuseki as a system level service on a typical Linux machine.
As you can see from the tutorial I linked to from my previous message, it's
currently a bit cumbersome to make it comply to the FHS. Naturally the chosen
directory layout also affects the systemd unit file.
