This template lists +# the most important settings you may want to configure for a production cluster. +# +# Please consult the documentation for further information on configuration options: +# https://www.elastic.co/guide/en/elasticsearch/reference/index.html +# +# ---------------------------------- Cluster ----------------------------------- +# +# Name of the Elasticsearch cluster. +# A node can only join a cluster when it shares its cluster.name with all the other nodes in the cluster. +# The default name is elasticsearch, but you should change it to an appropriate name which describes the +# purpose of the cluster. +# +cluster.name: $cluster.name +# +# ------------------------------------ Node ------------------------------------ +# +# It is better to provide different meaningfull names fot different elastic nodes. +# By default, Elasticsearch will take the 7 first character of the randomly generated uuid used as the node id. +# Note that the node id is persisted and does not change when a node restarts +# +#node.name: $node.name +# +# +# ----------------------------------- Paths ------------------------------------ +# +# The location of the data files of each index / shard allocated on the node. Can hold multiple locations separated by coma. +# In production, we should not keep this fixed, as on upgrading Elasticsearch, directory structure +# may change & can deal to data loss. +path.data: /usr/share/elasticsearch/data +# +# Elasticsearch's log files location. In production, we should not keep this default to "/elasticsearch/logs", +# as on upgrading Elasticsearch, directory structure may change. +path.logs: /usr/share/elasticsearch/logs +# +# ----------------------------------- Memory ----------------------------------- +# +# It is vitally important to the health of your node that none of the JVM is ever swapped out to disk. +# Lock the memory on startup. +# +bootstrap.memory_lock: true +# +# Make sure that the heap size is set to about half the memory available +# on the system and that the owner of the process is allowed to use this +# limit. +# +# Elasticsearch performs poorly when the system is swapping the memory. +# +# ---------------------------------- Network ----------------------------------- +# This IP is published for TCP & HTTP communications. +# HTTP is used for REST communications. +# TCP is used for communication between Elasticsearch cluster nodes +# If you have different different IPs for TCP & HTTP, you have to declare "transport.publish_host" & "http.publish_host" +# More info: https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html +network.publish_host: $network.publish_host +# +# Set the bind address to a specific IP (IPv4 or IPv6): +# In order to communicate and to form a cluster with nodes on other servers, your node will need to bind to a +# non-loopback address. +#network.host: "0.0.0.0" +# +# Set a custom port for HTTP: If required, default is 9200-9300 +# This is used for REST APIs +http.port: $http.port +# +# Port to bind for communication between nodes. Accepts a single value or a range. +# If a range is specified, the node will bind to the first available port in the range. +# Defaults to 9300-9400. +# More info: +transport.tcp.port: $transport.tcp.port +# +# For more information, consult the network module documentation. +# +# --------------------------------- Discovery ---------------------------------- +# +# Pass an initial list of hosts to perform discovery when new node is started: +# To form a cluster with nodes on other servers, you have to provide a seed list of other nodes in the cluster +# that are likely to be live and contactable. +# By default, Elasticsearch will bind to the available loopback addresses and will scan ports 9300 to 9305 to try +# to connect to other nodes running on the same server. +# +discovery.zen.ping.unicast.hosts: $discovery.zen.ping.unicast.hosts +# +# This setting tells Elasticsearch to not elect a master unless there are enough master-eligible nodes +# available. Only then will an election take place. +# Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1): +discovery.zen.minimum_master_nodes: 2 +# +# For more information, consult the zen discovery module documentation. +#
