How to config Single node for Single Cluster (Standalone Cluster) ElasticSearch

Question

I installed elastic search in my local machine, I want to configure it as the only one single node in the cluster(Standalone Server). it means whenever I create a new index, it

Answer 1

Here's relevant info for ElasticSearch 5:

According to changelog, to enable local mode on ES 5 you need to add transport.type: local to your elasticsearch.yml instead of node.local: true.

Answer 2

If you intend to run Elasticseach on a Single Node and be able to bind it to public IP, two important settings are:

network.host: <PRIVATE IP OF HOST>
discovery.type: single-node

Answer 3

In elasticsearch.yml

# Note, that for development on a local machine, with small indices, it usually
# makes sense to "disable" the distributed features:
#
index.number_of_shards: 1
index.number_of_replicas: 0

Use the same configuration in your code.

Also to isolate the node use node.local: true or discovery.zen.ping.multicast: false

I ve got the answer from http://elasticsearch-users.115913.n3.nabble.com/How-to-isolate-elastic-search-node-from-other-nodes-td3977389.html.

Kimchy : You set the node to local(true), this means it will not discover other nodes using network, only within the same JVM.

in elasticsearch/bin/elasticsearch.yml file

node.local: true # disable network

Answer 5

If you're using a network transport in your code, this won't work, as node.local gives you a LocalTransport only:

The trick then is to set

discovery.zen.ping.multicast: false

in your elasticsearch.yml which will stop your node looking for any other nodes.

I'm not sure if this prevents other nodes from discovering yours though; I only needed this to affect a group of nodes with the same settings on the same network.

Answer 6

This solve your problem:

PUT /_all/_settings
{"index.number_of_replicas":0}

Tested with ES version 5.
