systemd definition for solr?

Ryan W
Does anyone have a simple systemd definition for a solr service?

The things I am finding on the internet don't work.  I am not sure if this
is the kind of thing where there might be some boilerplate that (usually)
works?  Or do situations vary so much that no boilerplate is possible?

Here is what I see when I try to use one of the definitions I found on the
internet:

[root@faspbsy0002 system]# systemctl status solr.service
? solr.service - LSB: A very fast and reliable search engine.

I didn't realize that to start a systemd service, I need to do...

systemctl start solr

...and not...

service solr start

Now the output from the status command looks a bit better, though still
with some problems...

[root@faspbsy0002 system]# systemctl status solr.service
? solr.service - LSB: A very fast and reliable search engine.
   Loaded: loaded (/etc/rc.d/init.d/solr; bad; vendor preset: disabled)
   Active: active (exited) since Thu 2020-10-15 15:58:23 EDT; 19s ago
     Docs: man:systemd-sysv-generator(8)
  Process: 34100 ExecStop=/etc/rc.d/init.d/solr stop (code=exited,
status=1/FAILURE)
  Process: 98871 ExecStart=/etc/rc.d/init.d/solr start (code=exited,
status=0/SUCCESS)

I just needed to enable the service with....

systemctl enable solr.service

Re: systemd definition for solr?

Joe Doupnik
In reply to this post by Ryan W
     Close, but not quite there yet. The rules say use
         systemctl start (or stop or status) solr.service
That dot service part ought to be there. I suspect that if we omit it
then we may be scolded on-screen and lose some grade points.
     On your error report below. Best to ensure that Solr is started by
either /etc/init.d or systemd but not both. To check on the /etc/init.d
part, go to /etc/init.d and give command chkconfig -l solr. if the
result shows "On" for any run level then /etc/init.d is supposed to be
in charge rather than systemd. If that were the case then your systemd
control page ought to indicate that solr is a "LSB" process. On the
other hand, if systemd were to be the controlling agent then ensure that
the /etc/init.d part does not interfere by issuing command chkconfig -d
solr  which will unlink solr from its to-do list. Then say systemctl
enable solr    to let systemd take charge.
      Thus some busy work to check on things, and then making a choice
of which flavour will be in charge.
     Thanks,
     Joe D.
