Creating a cluster

Since you have learned a major part of cluster configuration, let's begin to create a full-blown production-ready cluster. In this example, we will configure a cluster with three master, two client nodes, and two data nodes.

The example shows a configuration of one master, one data, and one client node. On the rest of nodes, all the configuration will remain the same according to the node category, but only four parameters will be changed:

node.name, path.data, path.log and network.host.

Note

If you are configuring a new data or log path, make sure that Elasticsearch has the full permission of that directory. You can set the permission with the following command:

sudo chown -R elasticsearch:elasticsearch path_of_the_data_directory

Configuring master nodes

cluster.name: "production-cluster"
node.name: "es-master-01"
node.data: false
node.master: true
path.data: "path_to_data_directory"
network.host: "192.168.1.10" (should be changed to a private IP address of this machine or can be left out too, because Elasticsearch, by default, binds itself to the 0.0.0.0 address)
http.enabled: false
transport.tcp.port: 9300
discovery.zen.minimum_master_nodes: 3 
discovery.zen.ping.unicast.hosts: ["es-master-01:6300","es-master-02:6300", "es-master-03:6300"]
discovery.zen.ping.timeout: 5s
bootstrap.mlockall: true 
action.destructive_requires_name: true 
#For allowing script execution
script.inline: on

Configuring client nodes

cluster.name: "production-cluster"
node.name: "es-client-01"
node.data: false
node.master: false
network.host: "192.168.1.10" (should be changed to the private IP address of this machine)
http.enabled: true
http.port: 9200
transport.tcp.port: 9300 
discovery.zen.minimum_master_nodes: 3 
discovery.zen.ping.unicast.hosts: ["es-master-01:9300","es-master-02:9300", "es-master-03:9300"]
discovery.zen.ping.timeout: 5s
bootstrap.mlockall: true 
action.destructive_requires_name: true 
action.disable_delete_all_indices: false
script.inline: on
#To allow sense and marvel to query elasticsearch
http.cors.enabled: true
http.cors.allow-origin: /http://localhost(:[0-9]+)?/
http.cors.allow-credentials: true

Configuring data nodes

cluster.name: "production-cluster"
node.name: "es-data-01"
node.data: true
node.master: false
network.host: "192.168.1.10" (should be changed to the private IP address of this machine)
http.enabled: false
transport.tcp.port: 9300 
discovery.zen.minimum_master_nodes: 3 
discovery.zen.ping.unicast.hosts: ["es-master-01:9300","es-master-02:9300", "es-master-03:9300"]
discovery.zen.ping.timeout: 5s
bootstrap.mlockall: true 
action.destructive_requires_name: true 
script.inline: on
