1 # ======================== Elasticsearch Configuration =========================
3 # NOTE: Elasticsearch comes with reasonable defaults for most settings.
4 # Before you set out to tweak and tune the configuration, make sure you
5 # understand what are you trying to accomplish and the consequences.
7 # The primary way of configuring a node is via this file. This template lists
8 # the most important settings you may want to configure for a production cluster.
10 # Please see the documentation for further information on configuration options:
11 # <http://www.elastic.co/guide/en/elasticsearch/reference/current/setup-configuration.html>
13 # ---------------------------------- Cluster -----------------------------------
15 # Use a descriptive name for your cluster:
17 cluster.name: $clustername
19 # ------------------------------------ Node ------------------------------------
21 # Use a descriptive name for the node:
25 # Add custom attributes to the node:
29 # ----------------------------------- Paths ------------------------------------
31 # Path to directory where to store the data (separate multiple locations by comma):
33 # path.data: /path/to/data
36 path.plugins: etc/elasticsearch-plugins
40 # path.logs: /path/to/logs
42 # ----------------------------------- Memory -----------------------------------
44 # Lock the memory on startup:
46 # bootstrap.mlockall: true
48 # Make sure that the `ES_HEAP_SIZE` environment variable is set to about half the memory
49 # available on the system and that the owner of the process is allowed to use this limit.
51 # Elasticsearch performs poorly when the system is swapping the memory.
53 # ---------------------------------- Network -----------------------------------
55 # Set the bind address to a specific IP (IPv4 or IPv6):
57 # network.host: 192.168.0.1
58 network.bind_host: 0.0.0.0
59 network.publish_host: $hostname
61 # Set a custom port for HTTP:
65 # For more information, see the documentation at:
66 # <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html>
68 # --------------------------------- Discovery ----------------------------------
70 # Pass an initial list of hosts to perform discovery when new node is started:
71 # The default list of hosts is ["127.0.0.1", "[::1]"]
73 # discovery.zen.ping.unicast.hosts: ["host1", "host2"]
75 # Prevent the "split brain" by configuring the majority of nodes (total number of nodes / 2 + 1):
77 # discovery.zen.minimum_master_nodes: 3
79 # For more information, see the documentation at:
80 # <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-discovery.html>
82 # ---------------------------------- Gateway -----------------------------------
84 # Block initial recovery after a full cluster restart until N nodes are started:
86 # gateway.recover_after_nodes: 3
88 # For more information, see the documentation at:
89 # <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-gateway.html>
91 # ---------------------------------- Various -----------------------------------
93 # Disable starting multiple nodes on a single system:
95 # node.max_local_storage_nodes: 1
97 # Require explicit names when deleting indices:
99 # action.destructive_requires_name: true
101 # Required for Kibana 4.x support
102 index.max_result_window: 2147483647
103 #transport.tcp.port: 9301
