nupic-history-server and htm-school-viz expect the same port for redis

[breznak]

nupic-history-server is a dependency for htm-schoool-viz since Ep.8+, there is mentioned that htm-school-viz expect redis tu run on port 8000.

While redis-server by default runs on 6379 - change either of them, so that the defaults match.

The error manifests as:

(schools) mmm@mmm-U2442:/mnt/store/devel/HTM/htm_schools/htm-school-viz$ npm start 8080

> htm-school-viz@1.0.0 start /mnt/store/devel/HTM/htm_schools/htm-school-viz
> node index.js "8080"

See https://github.com/htm-community/htm-school-viz/issues/19

• redis should run on 6379
• nupic-history-server should run on 8000
• htm-school-viz can run on any port, but defaults to 8080

Thanks @rikkertkoppes ! I really got that confused.

But still:

1. run redis-server (default 6379) ...OK
2. how do I run the "history server"? I assume python webserver.py , but it defaults to :8080 ...FAIL *)
3. run "htm schools" npm start

*) as you see, I think the ports are still switched:

• history server runs on 8080, and I don;t know how to change that
• I can change "htm schools" to run on arbitrary port, say 8001
  • I can change "htm schools" to expect "history" to be at :8080, which then fits :grey_question: BUT: I'd still get
