Ah so, systemd style. I suggestion which might help. Look at the
/etc/init.d style script in the Solr distribution and uses its commands
as a reference when you review the systemd equivalents. In addition, a
prerequisite is choosing the user+group for Solr files, applying
ownership of those files, and ensuring the systemd script uses that user
information (which the init.d script does via that RUNAS item). Solr''s
offered /etc/init.d file is in installation directory ~/solr/bin/init.d
as file solr.
For systemd I control apps via commands of the form systemctl start
solr.service.
Thanks,

Alex has it right. In my environment I created user "solr" in group
"users". Then I ensured that "solr:user" owns all of Solr's files. In
addition, I do Solr start/stop with an /etc/init.d script (the Solr
distribution has the basic one which we can embellish) in which there is
control line RUNAS="solr". The RUNAS variable is used to properly start
Solr.

It sounds like maybe you have started the Solr in a different way than
you are restarting it. E.g. maybe you started it manually (bin/solr
start, probably as a root) but are trying to restart it via service
script. Who owned the .pid file? I am guessing 'root', while the
service script probably runs as a different (lower-permission) user.
The practical effect of that assumption is that your environmental
variables were set differently and various things (e.g. logs) may not
be where you expect.
The solution is to be consistent in using the service to
start/restart/stop your Solr.

What is my permissions problem here:
[root@faspbsy0002 bin]# service solr restart
Sending stop command to Solr running on port 8983 ... waiting up to 180
seconds to allow Jetty process 38947 to stop gracefully.
/opt/solr/bin/solr: line 2125: /opt/solr/bin/solr-8983.pid: Permission
denied
What is the practical effect if Solr can't write this solr-8983.pid
file?
What user should own the contents of /opt/solr/bin ?
Thanks
