it's surprisingly hard to install Solr in a way where I can guarantee to automatically get updates, especially security updates in a reliable manner, as well as get a documented way to start / run Solr on my distro of choice.
What I am really looking for is an official rpm repository (and probably a deb repo too) that I can add to my package manager and then install a package that will give me all the updates I want, as well as starts the database with a systemd file that is known good.
I in particular am looking for a centos 7 repository.
I think, that this would make installation of Solr so much easier.
What do you say?
