Create a local Nginx-based proxy for <http://download.elasticsearch.org> for demos at conferences, meetups, etc

download.elasticsearch.conf

# Create a local proxy for <http://download.elasticsearch.org>
# ============================================================
#
# This setup and Nginx configuration provides a local webserver which intercepts requests
# to <http://download.elasticsearch.org> and serves a local file instead,
# facilitating and speeding up demonstrations at conferences, meetups, etc.
#
#
# 1. Create directories for Nginx:
#
#     $ mkdir -pv tmp/logs tmp/html
#
# 2. Download the Elasticsearch archive from the internet
#
#     $ curl -# -O https://download.elasticsearch.org/elasticsearch/elasticsearch/elasticsearch-0.90.5.tar.gz
#
# 3. Add intercepting into `/etc/hosts`
#
#     $ grep download.elasticsearch /etc/hosts || \
#       sudo sh -c 'echo "127.0.0.1 download.elasticsearch.org\n::1 download.elasticsearch.org" >> /etc/hosts'
#
# 4. Launch Nginx
#
#     $ sudo nginx -p "$PWD/tmp/" -c "$PWD/download.elasticsearch.conf"
#
# Use the <http://download.elasticsearch.org> URL in your scripts:
#
#     $ curl -I http://download.elasticsearch.org/elasticsearch/elasticsearch/elasticsearch-0.90.5.tar.gz
#
#
# Stop Nginx with:
#
#     $ sudo nginx -p "$PWD/tmp/" -c ../download.elasticsearch.conf -s quit
#
