Define cluster and data replication in Elasticsearch 6.4

[kolli_dilip]

Hi

Can some one suggest me how to define the cluster details (ip's) and the data replication values in the new elasticsearch.yml, the below is my present yml

---------------------------------- Cluster -----------------------------------

Use a descriptive name for your cluster:

cluster.name: mycluster

------------------------------------ Node ------------------------------------

Use a descriptive name for the node:

node.name: node-1

Add custom attributes to the node:

#node.attr.rack: r1

--------------------------------- Discovery ----------------------------------

Pass an initial list of hosts to perform discovery when new node is started:

The default list of hosts is ["127.0.0.1", "[::1]"]

discovery.zen.ping.unicast.hosts: ["ip1", "ip2"]

Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):

#discovery.zen.minimum_master_nodes:

Thanks

1. Please format your code as code, so it's properly readable
2. Replication is set per index (or globally or via a template) via the API. See https://www.elastic.co/guide/en/elasticsearch/reference/6.4/indices-create-index.html#create-index-settings for the creation and https://www.elastic.co/guide/en/elasticsearch/reference/6.4/indices-update-settings.html#indices-update-settings for update settings.
3. To form a cluster you need to configure the IP addresses / DNS names of the other nodes in discovery.zen.ping.unicast.hosts

Thank-you @xeraa, can you please let me know how to add security (xpack) configuration on elasticsearch.yml, i belive there has to be some added notations of xpack in the elasticsearch.yml, or is there any other way

[xeraa]

Assuming you have the default package, which includes X-Pack, you need to start a trial and then enable security: https://www.elastic.co/guide/en/elasticsearch/reference/current/security-settings.html

Though this is another topic. If you have more questions about X-Pack or security, please start another discussion.
