I stopped the Solr by using
* /sudo /opt/solr/bin/solr stop -force/
Then tried using restarting by using:
* /sudo service solr start
/
* /sudo systemctl start/
The results of both commands indicated that solr started but I could not
get to the admin ui.
Checked the process id, indicated from the results but there was none.
Based on what Shawn said, I must have overridden the service name but I
can't image how and when, seeing that they once worked.
Funny enough, if I start the Solr using
* /sudo /opt/solr/bin/solr stop -force/
The stop it using:
* /sudo service solr stop/
It stops.
Can someone please advise?/

When you install Solr, the service starts as root just like every
other service, and switches to the unprivileged user as part of
startup. This switch happens in the service script, not in the solr
script.
What happens if you type this command?
sudo service solr restart
This assumes that when you installed Solr that you did not override
the service name. If you did, then you will have to change "solr" in
that command to the actual service name you used.
You should not be calling the solr script directly, even as the solr
user. Ran in this way, it will not be configured correctly even if it
does start ... and chances are that it won't even start.
The installation script creates the solr user without a working
password, not even a blank password.
Thanks,
Shawn
