Hello, How did you installed Solr?, have you followed this instructions?: https://lucene.apache.org/solr/guide/7_0/taking-solr-to-production.html#taking-solr-to-production
On that instructions you first extracts an script file from inside the tar.gz. Then running that script file with a few options, it install the required files, creates the solr user and folders and starts (or not if you use that option) the solr daemon from /etc/init.d/solr. After all, you'll have a solr user, a file in /etc/init.d/solr that runs the daemon at boot, and a file in /etc/default/solr (i don't rememeber the entire name), that is for configure the daemon. I'm not fully sure if is different on Ubuntu, but showld be similar. Greetings!
