I did a bit of digging around and only found a handful of long procedures like say the one on Digital Ocean for Ubuntu 14, which actually is pretty good. But there is still an awful lot of things to keep in mind. I dug up the usual sources, but found no script that would actually automate the entire process from Java through install to core creation.
I wrote an end-to-end Solr installer script for RedHat and was wondering if there is one for Ubuntu I may have missed? Or should I actually devote some time and write it myself?
