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,

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...

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:
