Hide Elasticsearch behind Apache HTTP server

Requirements

1. Elasticsearch instance up and running.
2. Apache HTTP server. If you haven't install it already, you can get Apache installed on your server through apt-get:

sudo apt-get update

sudo apt-get install apache2

Setup mod_proxy

Install and enable mod_proxy so Apache can forward requests to any ports you want:

apt-get install libapache2-mod-proxy-html
a2enmod proxy
a2enmod proxy_http

Either create or edit a vhost for elasticsearch.

In this case we are going to edit Apache's default vhost 000-default.conf.

1. Open the file 000-default.conf vi /etc/apache2/sites-available/default-000.conf
2. Add a new location. You can copy an paste the code bellow, just replace %your_location% with the location you want to use.

#ProxyPass http://localhost:9200/
<Location /%your_location%>
     ProxyPass http://localhost:9200/
     ProxyPassReverse http://localhost:9200/
</Location>

1. Save and close the file. If necessary restart Apache.
2. In your browser try to access elastic search by navigating to %your_location%.

http://localhost/%your_location%
