+##################### Elasticsearch Configuration Example #####################
|
|
|
+
|
|
|
+# This file contains an overview of various configuration settings,
|
|
|
+# targeted at operations staff. Application developers should
|
|
|
+# consult the guide at <http://elasticsearch.org/guide>.
|
|
|
+#
|
|
|
+# The installation procedure is covered at
|
|
|
+# <http://elasticsearch.org/guide/en/elasticsearch/reference/current/setup.html>.
|
|
|
+#
|
|
|
+# Elasticsearch comes with reasonable defaults for most settings,
|
|
|
+# so you can try it out without bothering with configuration.
|
|
|
+#
|
|
|
+# Most of the time, these defaults are just fine for running a production
|
|
|
+# cluster. If you're fine-tuning your cluster, or wondering about the
|
|
|
+# effect of certain configuration option, please _do ask_ on the
|
|
|
+# mailing list or IRC channel [http://elasticsearch.org/community].
|
|
|
+
|
|
|
+# Any element in the configuration can be replaced with environment variables
|
|
|
+# by placing them in ${...} notation. For example:
|
|
|
+#
|
|
|
+#node.rack: ${RACK_ENV_VAR}
|
|
|
+
|
|
|
+# For information on supported formats and syntax for the config file, see

|
|
+# Cluster name identifies your cluster for auto-discovery. If you're running

+#################################### Node #####################################
|
|
|
+
|
|
|
+# Node names are generated dynamically on startup, so you're relieved
|
|
|
+# from configuring them manually. You can tie this node to a specific name:
|
|
|
+#
|
|
|
+#node.name: "Franz Kafka"
|
|
|
+
|
|
|
+# Every node can be configured to allow or deny being eligible as the master,
|
|
|
+# and to allow or deny to store the data.
|
|
|
+#
|
|
|
+# Allow this node to be eligible as a master node (enabled by default):
|
|
|
+#
|
|
|
+#node.master: true
|
|
|
+#
|
|
|
+# Allow this node to store data (enabled by default):
|
|
|
+#
|
|
|
+#node.data: true
|
|
|
+
|
|
|
+# You can exploit these settings to design advanced cluster topologies.
|
|
|
+#
|
|
|
+# 1. You want this node to never become a master node, only to hold data.
|
|
|
+# This will be the "workhorse" of your cluster.
|
|
|
+#
|
|
|
+#node.master: false
|
|
|
+#node.data: true
|
|
|
+#
|
|
|
+# 2. You want this node to only serve as a master: to not store any data and
|
|
|
+# to have free resources. This will be the "coordinator" of your cluster.
|
|
|
+#
|
|
|
+#node.master: true
|
|
|
+#node.data: false
|
|
|
+#
|
|
|
+# 3. You want this node to be neither master nor data node, but
|
|
|
+# to act as a "search load balancer" (fetching data from nodes,
|
|
|
+# aggregating results, etc.)
|
|
|
+#
|
|
|
+#node.master: false
|
|
|
+#node.data: false
|
|
|
+
|
|
|
+# Use the Cluster Health API [http://localhost:9200/_cluster/health], the

+# <http://mobz.github.com/elasticsearch-head> to inspect the cluster state.
|
|
|
+
|
|
|
+# A node can have generic attributes associated with it, which can later be used
|
|
|
+# for customized shard allocation filtering, or allocation awareness. An attribute
|
|
|
+# is a simple key value pair, similar to node.key: value, here is an example:
|
|
|
+#
|
|
|
+#node.rack: rack314
|
|
|
+
|
|
|
+# By default, multiple nodes are allowed to start from the same installation location
|
|
|
+# to disable it, set the following:
|
|
|
+#node.max_local_storage_nodes: 1

+#################################### Index ####################################
|
|
|
+
|
|
|
+# You can set a number of options (such as shard/replica options, mapping
|
|
|
+# or analyzer definitions, translog settings, ...) for indices globally,
|
|
|
+# in this file.
|
|
|
+#
|
|
|
+# Note, that it makes more sense to configure index settings specifically for
|
|
|
+# a certain index, either when creating it or by using the index templates API.
|
|
|
+#
|
|
|
+# See <http://elasticsearch.org/guide/en/elasticsearch/reference/current/index-modules.html> and
|
|
|
+# <http://elasticsearch.org/guide/en/elasticsearch/reference/current/indices-create-index.html>
|
|
|
+# for more information.
|
|
|
+
|
|
|
+# Set the number of shards (splits) of an index (5 by default):
|
|
|
+#
|
|
|
+#index.number_of_shards: 5
|
|
|
+
|
|
|
+# Set the number of replicas (additional copies) of an index (1 by default):
|
|
|
+#
|
|
|
+#index.number_of_replicas: 1
|
|
|
+
|
|
|
+# Note, that for development on a local machine, with small indices, it usually
|
|
|
+# makes sense to "disable" the distributed features:
|
|
|
+#
|
|
|
+#index.number_of_shards: 1
|
|
|
+#index.number_of_replicas: 0
|
|
|
+
|
|
|
+# These settings directly affect the performance of index and search operations
|
|
|
+# in your cluster. Assuming you have enough machines to hold shards and
|
|
|
+# replicas, the rule of thumb is:
|
|
|
+#
|
|
|
+# 1. Having more *shards* enhances the _indexing_ performance and allows to
|
|
|
+# _distribute_ a big index across machines.
|
|
|
+# 2. Having more *replicas* enhances the _search_ performance and improves the
|
|
|
+# cluster _availability_.
|
|
|
+#
|
|
|
+# The "number_of_shards" is a one-time setting for an index.
|
|
|
+#
|
|
|
+# The "number_of_replicas" can be increased or decreased anytime,
|
|
|
+# by using the Index Update Settings API.
|
|
|
+#
|
|
|
+# Elasticsearch takes care about load balancing, relocating, gathering the
|
|
|
+# results from nodes, etc. Experiment with different settings to fine-tune
|
|
|
+# your setup.
|
|
|
+
|
|
|
+# Use the Index Status API (<http://localhost:9200/A/_status>) to inspect
|
|
|
+# the index status.

|
|

|
|

+############################## Network And HTTP ###############################
|
|
|
+
|
|
|
+# Elasticsearch, by default, binds itself to the 0.0.0.0 address, and listens
|
|
|
+# on port [9200-9300] for HTTP traffic and on port [9300-9400] for node-to-node
|
|
|
+# communication. (the range means that if the port is busy, it will automatically
|
|
|
+# try the next port).
|
|
|
+
|
|
|
+# Set the bind address specifically (IPv4 or IPv6):
|
|
|
+#
|
|
|
+#network.bind_host: 192.168.0.1
|
|
|
+
|
|
|
+# Set the address other nodes will use to communicate with this node. If not
|
|
|
+# set, it is automatically derived. It must point to an actual IP address.

+#
|
|
|
+#network.publish_host: 192.168.0.1
|

|
|
|
+#network.host: 192.168.0.1
|

+################################### Gateway ###################################
|
|
|
+
|
|
|
+# The gateway allows for persisting the cluster state between full cluster

|
+# restarts. Every change to the state (such as adding an index) will be stored
|
|
|
+# in the gateway, and when the cluster starts up for the first time,
|

|
+# it will read its state from the gateway.
|
|
|
+
