- # ======================== Elasticsearch Configuration =========================
- #
- # NOTE: Elasticsearch comes with reasonable defaults for most settings.
- # Before you set out to tweak and tune the configuration, make sure you
- # understand what are you trying to accomplish and the consequences.
- #
- # The primary way of configuring a node is via this file. 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 -----------------------------------
- #
- # Use a descriptive name for your cluster:
- #
- cluster.name: graylog
- #
- # ------------------------------------ Node ------------------------------------
- #
- # Use a descriptive name for the node:
- #
- #node.name: node-1
- #
- # Add custom attributes to the node:
- #
- #node.attr.rack: r1
- #
- # ----------------------------------- Paths ------------------------------------
- #
- # Path to directory where to store the data (separate multiple locations by comma):
- #
- path.data: /var/lib/elasticsearch
- #
- # Path to log files:
- #
- path.logs: /var/log/elasticsearch
- #
- # ----------------------------------- Memory -----------------------------------
- #
- # 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 -----------------------------------
- #
- # Set the bind address to a specific IP (IPv4 or IPv6):
- #
- #network.host: 192.168.0.1
- #
- # Set a custom port for HTTP:
- #
- #http.port: 9200
- #
- # For more information, consult the network module documentation.
- #
- # --------------------------------- 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: ["host1", "host2"]
- #
- # Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):
- #
- #discovery.zen.minimum_master_nodes:
- #
- # For more information, consult the zen discovery module documentation.
- #
- # ---------------------------------- Gateway -----------------------------------
- #
- # Block initial recovery after a full cluster restart until N nodes are started:
- #
- #gateway.recover_after_nodes: 3
- #
- # For more information, consult the gateway module documentation.
- #
- # ---------------------------------- Various -----------------------------------
- #
- # Require explicit names when deleting indices:
- #
- #action.destructive_requires_name: true
- action.auto_create_index: false
