Running Fuseki as a Daemon or Windows Service
I see a number of oblique references online to running Fuseki as a *nix daemon. However, I see no clear procedure for doing so. Is such documentation written anywhere?
Also, and equally important to my customers, is there a way to run Fuseki as a Windows Service?
Thanks,
Ian

Well, I won't get an msi... running
mvn windows-service-installer:installer
on https://github.com/steinarb/fusekiservice currently gets me this, in
the target directory:
-rw-rw-rw- 1 sb None 92126065 02-07 09:06 fusekiservice-0.0.1-SNAPSHOT-installer.zip
-rw-rw-rw- 1 sb None 24859992 02-07 09:06 install.jar
Double-clicking on the "install.jar" starts an IzPack installer of the
stuff in the zip file (which in its the current state doesn't include
the unpacked jena fuseki webapp, so the it won't actually run).
(Note: I haven't actually run the installer fully through yet. I think I
will use a VM for that, at least for the first couple of runs)

Not something I _need_ to do, just something I would like to try out.
I stumbled over this maven plugin
https://github.com/alexkasko/windows-service-installer
and thought "hey, an MSI that would install jena fuseki as a windows
service, that would be kind of cool".

An msi would give an easier installation procedure for windows
sysadmins. Fewer parts in motion that can go wrong.

Hi Steinar,
I'm wondering why you need to write a java driver.
Is there something that the standalone server command line won't do for
you? You can give a whole Jetty config file but "--port=4000" seems to
do what you want.
A cmd script to run a service then makes running your setup easy - it's
a common way to setup services on Windows (and Linux).
Or run the WAR in Tomcat because running tomcat as a service on windows
is well documented with lots of help on StackOverflow and elsewhere.
Or repackage a custom setup in a WAR file (that's what they are for
after all).
Fuseki needs to find the content for the UI. In standalone server form,
the webpages are outside the jar and the code needs to find them. In
war file form, the web pages are in the war file. In a war file,
FUSEKI_HOME is not needed - createWebApp isn't called.
If FUSEKI_HOME is null, then it looks in "webapp" and "src/main/webapp"
(more for develoopment mode) but setting environment variable
FUSEKI_HOME is better.

I've switched the port back to the default 3030, but it is easily
modified in the jenafusekiservice.properties file.

The current version installs in
C:\Program Files\Apache\Jena\Fuseki
and the Fuseki data directory will be
C:\Program Files\Apache\Jena\Fuseki\run
with the TDB databases placed in
C:\Program Files\Apache\Jena\Fuseki\run\databases
The value of the "run" directory can be modified by setting the
jena.fuseki.datalocation property in the jenafusekiservice.properties
file:

This still is valid.

Even more progress. With the current state of
https://github.com/steinarb/fusekiservice the installer installs, and
starts a service, running Jena Fuseki, that listens to port 4000.
I haven't actually tried using it... for one thing, I don't presently
know where TDB will put its database... but Jena Fuseki starts and runs,
and that's definitely progress.
Stop and Start works from the Windows Services window.
Instructions for running the installer and uninstall can be found in the
README file of https://github.com/steinarb/fusekiservice
The uninstaller will stop the service, and uninstall it.

Progress!
Now the webapp starts in the unit test.
Unfortunately, it doesn't stop yet. This means that calling
JettyFuseki.instance.join()
like I do in FusekiService.stopDaemon() was not the way to stop the
server... I have to read a bit more code, I guess...?
What I did was to unpack the jena fuseki webapp where the unit test
would find it ("./webapp" from the CWD of the unit test):
https://github.com/steinarb/fusekiservice/commit/87dbb7be634a0b26137854798eaeaef7074ba5cf
I get the following on the console:
[2016-02-06 12:17:45] FusekiService INFO FUSEKI_HOME: null
[2016-02-06 12:17:46] Server INFO Fuseki 2.3.1 2015-12-08T09:24:07+0000
[2016-02-06 12:17:46] Config INFO FUSEKI_HOME=unset

[2016-02-06 12:17:47] Server INFO Started 2016/02/06 12:17:47 CET on port 4000
And the webapp starts and listens to port 4000.
Unfortunately the unit test never stops, and killing the unit test
leaves the webapp running, so there is still a way to go...
Trying to create a Jena Fuseki Windows Service installer (Was: Running Fuseki as a Daemon or Windows Service)
Posted by Steinar Bang <sb...@dod.no>.
Hi,
I am trying to use the windows-service-installer maven plugin to create
a windows installer that will install a windows service that will run
Jena Fuseki.
https://github.com/alexkasko/windows-service-installer
My DaemonLauncher for Jena Fuseki, is here:
https://github.com/steinarb/fusekiservice/blob/master/src/main/java/no/priv/bang/fuseki/fusekiservice/FusekiService.java
I have written a JUnit test that attempts to start and stop the service
(just to see if I can make it run at all).
https://github.com/steinarb/fusekiservice/blob/master/src/test/java/no/priv/bang/fuseki/fusekiservice/FusekiServiceTest.java
The JUnit test currently fails with the following console output:
[2016-01-31 18:21:38] FusekiService INFO FUSEKI_HOME: null
[2016-01-31 18:21:38] Server ERROR Can't find resourceBase (tried webapp and src/main/webapp)
[2016-01-31 18:21:38] Server ERROR Failed to start
So my question is: what am I missing from the FusekiService.startDaemon() method?
I have been stealing code from here (mainly):
https://github.com/apache/jena/blob/master/jena-fuseki2/jena-fuseki-core/src/main/java/org/apache/jena/fuseki/cmd/FusekiCmd.java
The reason I haven tried using FusekiCmd, is that I would like to have
JettyFuseki.instance.start();
in the startDaemon() method, and
JettyFuseki.instance.join();
in the stopDaemon() method (unless I've misunderstood how they are
supposed to work...?)
The failing code, is in
https://github.com/apache/jena/blob/master/jena-fuseki2/jena-fuseki-core/src/main/java/org/apache/jena/fuseki/jetty/JettyFuseki.java
in the JettyFuseki.createWebApp() method.
The code in createWebapp() looks like it expects a directory, with
WEB-INF/web.xml residing in that directory (ie. WEB-INF a subdirectly of
the webapp directory), so I have been toying with the idea of
downloading and unpacking the fuseki webapp in a directory and give that
directory.
But even if I could make that work in a JUnit test, I have no idea of
how to accomplish the same thing in a windows service installed by an
installer created by the windows-service-installer maven plugin...
And the ready packaged jena fuseki starts and runs from a single .jar,
so unpacking something shouldn't be necessary.
So how should I proceed with this? Is this doable?
Thanks!

See
https://svn.apache.org/repos/asf/jena/branches/jena-fuseki-new-ui/fuseki
for now.
It's normal init/service(8) script.

There is no reason why not if such a thing were contributed. i don't
know how to run java services on Windows.
There will be a .WAR version as well but maybe not for the first v2
release. It works; the setting up of the file area needs to be properly
integrated into usual practice.
