sudo dpkg -i elasticsearch-5.5.0.deb
 
#Start and Stop the Elastic Search
sudo -i service elasticsearch start
sudo -i service elasticsearch stop

Do the following changes Example Elasticsearch.yml and update the following parameters:

Elastic Search Single Node

ZEE Server and Elastic Search is in same Server

Single node Elastic Search

cluster.name: zephyr
node.name: "Node1"
node.master: true
node.data: true
transport.tcp.port: 9300
http.port: 9200
script.inline: true
script.stored: true
indices.query.bool.max_clause_count: 9012

ZEE and Elastic Search in Different Server

Single node Elastic Search

cluster.name: zephyr
node.name: "Node1"
node.master: true
node.data: true
script.inline: true
script.stored: true
network.bind_host: 192.168.45.21
network.publish_host: 192.168.45.21
network.host: 192.168.45.21
transport.tcp.port: 9300
http.port: 9200
discovery.zen.ping.unicast.hosts: ["192.168.45.21:9300"]
indices.query.bool.max_clause_count: 9012

Sample elasticsearch.yml file attached : Example Elasticsearch.yml

Changes need to do in Zephyr

In Jdbc properties need to change
#transport|node
transport.nodes=192.168.45.21:9300, 192.168.45.22:9300

ElasticSearch Cluster

Elastic Search in cluster should be in Odd Number minimum node to be in elastic search cluster should be 3 node
Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):

cluster node Elastic Search

#ESNode 1 (192.168.11.144)
 
cluster.name: zephyr
node.name: "ESNode1"
node.master: true
node.data: true
network.host: 192.168.11.144
http.port: 9200
transport.tcp.port: 9300
network.bind_host: 192.168.11.144
network.publish_host : 192.168.11.144
discovery.zen.ping.unicast.hosts: ["192.168.11.144:9300","192.168.11.145:9300","192.168.11.146:9300"]
discovery.zen.minimum_master_nodes: 2
script.inline: true
script.stored: true
indices.query.bool.max_clause_count: 9012
 
------------------------------------------------------------------------------------------------------------------------------------
 
#ESNode 2 (192.168.11.145)
 
cluster.name: zephyr
node.name: "ESNode2"
node.master: true
node.data: true
network.host: 192.168.11.145
http.port: 9200
transport.tcp.port: 9300
network.bind_host: 192.168.11.145
network.publish_host : 192.168.11.145
discovery.zen.ping.unicast.hosts: ["192.168.11.144:9300","192.168.11.145:9300","192.168.11.146:9300"]
discovery.zen.minimum_master_nodes: 2
script.inline: true
script.stored: true
indices.query.bool.max_clause_count: 9012
 
---------------------------------------------------------------------------------------------------------------------------------------


#ESNode 3 (192.168.11.146)
 
cluster.name: zephyr
node.name: "ESNode3"
node.master: true
node.data: true
network.host: 192.168.11.146
http.port: 9200
transport.tcp.port: 9300
network.bind_host: 192.168.11.146
network.publish_host : 192.168.11.146
discovery.zen.ping.unicast.hosts: ["192.168.11.144:9300","192.168.11.145:9300","192.168.11.146:9300"]
discovery.zen.minimum_master_nodes: 2
script.inline: true
script.stored: true
indices.query.bool.max_clause_count: 9012

NOTE :

discovery.zen.ping.unicast.hosts should contain all the elasticsearch system's host ip and port which are in cluster.

Sample elasticsearch.yml file attached :

ESNode 1	Example ES 1
EsNode 2	Example ES 2
EsNode 3	Example ES 3

If elastic Search is in Cluster then in ZE we have to change the "number_of_shards" and "number_of_replicas"

Navigate to the ZE installation Dir

C:\Program Files\Zephyr\tomcat\webapps\flex\WEB-INF\template\zephyr

In this file _settings.json

change the number of shards and number of replicas

{
"index" : {
"number_of_shards" : 2,
"number_of_replicas" : 1
}
}

NOTE: for single node of the Elastic search this configuration should be default

Changes need to do in Zephyr

In Jdbc properties need to change
#transport|node
transport.nodes=192.168.11.144:9300,192.168.11.145:9300.192.168.11.146:9300
