Jan Høydahl commented on SOLR-6734:
-----------------------------------
What do you mean by “service” here? Process or OS service/daemon?
I like the idea of evolving the control scripts+SolrCLI into a new binary
(jar?) which can work one-off as today or optionally run in the background and
then be able to monitor, restart etc other processes.
Good old FAST ESP username to have exactly this, called the node controller
(nctrl). You would simply say “nctrl start nctrl” and it would start itself as
a daemon, looking at its config for what processes to start. Then you could use
the same binary to control the controller “nctrl restart qrserver”. And of
course it took commands from the GUI. The only process running as an OS service
was the node controller.
Perhaps such software exists in open source already, flexible enough to use?
