How to config Single node for Single Cluster (Standalone Cluster) ElasticSearch
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 networkUpdated for ES 7.x
in elasticsearch.yml
network.host: 0.0.0.0discovery.type: single-nodeand make sure you have cluster.initial_master_nodes off
# cluster.initial_master_nodes: ["node-1", "node-2"]credited to @Chandan.
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: 1index.number_of_replicas: 0Use the same configuration in your code.
Also to isolate the node use node.local: true or discovery.zen.ping.multicast: false
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.
