CentOS 7/systemd startup script for fuseki

Hi everybody,

Has anybody a proper systemd startup script for fuseki in place?

So far I use an entry for the "fuseki" init.d script in /etc/rc.local, which works after making the latter executable. But perhaps the problem has been solved in a better way.

Cheers, Joachim

Hi Osma,

Thank you so much - works beautifully and without modification under RH/CentOS 7.4

Cheers, Joachim

+1. At the least, we will have provided a starting point, and I believe that users will find that helpful in and of itself.

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!

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.

+1 for inclusion, and for consideration of more FHS compatible directory layout, too. 

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.

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."

Cheers, Joachim

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.

Is this worth including in the distribution as a file, or maybe just in "README"-type docs?

Hi Joachim!

Glad you asked, I've been on sitting on one for a while and thought it 
should be shared but never got to it.

Mine is included at the bottom of the message. It's for an Ubuntu 16.04 
system where Fuseki has been installed according to the Skosmos tutorial 
[1] i.e. with symlinks that make it fit better into a Linux FHS layout. 
It's placed at /etc/systemd/system/fuseki.service
