SOLR will not run from systemd

David Smith

RHEL 7.5, TS 16.4.1

I have installed Zookeeper and SOLR and created wrapper scripts to run SOLR as non-root. When I run my scripts from the command line, they work beautifully. SOLR starts and I can see it's status on the browser. Perfection. However, when I attempt to create the systemd service and run my scripts from the service, I am unable to start/stop SOLR this way. I'm not seeing any useful logging. When I run a status after attempting to start, I see this:

● solr1.service - Solr1 Service

Googling this message is not getting me anywhere. Has anyone successfully been able to get SOLR started from systemd using a wrapper script?

This is my solr1.service:
