COUCH DB INSTALLATION ON RASPBERRY PI
======================================================================================================================
https://github.com/apache/couchdb/releases/tag/2.3.0
http://tplinkwifi.net/
https://andyfelong.com/2017/09/couchdb-2-1-on-raspberry-pi-raspbian-stretch/



cd /home/couchdb/etc
sudo -i -u couchdb /home/couchdb/bin/couchdb

START CouchDb:
sudo -i -u couchdb /home/couchdb/bin/couchdb

Issues:
1. After setting up couch db ensure that you go to settings and select "configure for single node". Else it will trow a write permission required and no documents will be written on the db
2. Keep the db port as 5000
