This is for new ElasticSearch user.

If you have installed elastic search and unable to install plugins, here are the easy steps.

1. Type this command

$ curl "localhost:9200/_nodes/settings?pretty=true"

Locate your home directory ( Look for Settings -> Path -> Home for value )
2. Go to Location (Example on the picture above)

 cd /opt/kibana/esvm/dev/branch-2.3" 

Install Plugin (Example plugin: mobz/elasticsearch-head)

 sudo bin/plugin install mobz/elasticsearch-head

If you are using old elasticSearch use "-install" instead of just install

I have ES 2.1.0 and the command is : sudo bin/plugin install mobz/elasticsearch-head  for me

How to test –

Open this URL

http://localhost:9200/_plugin/head/

If you see this, your plugin is working.

similarly, you can install other plugins –

sudo bin/plugin install https://github.com/AIsaac08/bigdesk/archive/master.zip

Command which is given in the site is not working on 29th of Nov 2015
