Using nginx as a reverse proxy, installing in Ubuntu 14.04

Sample nginx configuration changes:
nginx.conf
default

Install nginx in Ubuntu 14.04
Refer: https://www.digitalocean.com/community/tutorials/how-to-install-nginx-on-ubuntu-14-04-lts

$ sudo apt-get update
$ sudo apt-get install nginx

It runs under localhost by default.

Manage the Nginx Process

$ sudo service nginx stop
$ sudo service nginx start
$ sudo service nginx restart

Location of default HTML files for nginx:
/usr/share/nginx/html

Change permissions to allow easy access to files:
$ sudo chown -R $USERID:$USERID /usr/share/nginx/html
$ sudo chmod -R 755 /usr/share/nginx/html

You can copy the "build" folder there now for testing, make sure to restart nginx
http://localhost/build/index.html#/?token=1m5rel70oem7e035c2puba6ueo
