# ======================== 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 see the documentation for further information on configuration options: # # # ---------------------------------- Cluster ----------------------------------- # # Use a descriptive name for your cluster: # # cluster.name: my-application # # ------------------------------------ Node ------------------------------------ # # Use a descriptive name for the node: # # node.name: node-1 # # Add custom attributes to the node: # # node.rack: r1 # # ----------------------------------- Paths ------------------------------------ # # Path to directory where to store the data (separate multiple locations by comma): # # path.data: /path/to/data # # Path to log files: # # path.logs: /path/to/logs # # ----------------------------------- Memory ----------------------------------- # # Lock the memory on startup: # # bootstrap.mlockall: true # # Make sure that the `ES_HEAP_SIZE` environment variable 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 adress 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, see the documentation at: # # # ---------------------------------- Gateway ----------------------------------- # # Block initial recovery after a full cluster restart until N nodes are started: # # gateway.recover_after_nodes: 3 # # For more information, see the documentation at: # # # --------------------------------- Discovery ---------------------------------- # # Elasticsearch nodes will find each other via multicast, by default. # # To use the unicast discovery, disable the multicast discovery: # # discovery.zen.ping.multicast.enabled: false # # Pass an initial list of hosts to perform discovery when new node is started: # # discovery.zen.ping.unicast.hosts: ["host1", "host2"] # # Prevent the "split brain" by configuring the majority of nodes (total number of nodes / 2 + 1): # # discovery.zen.minimum_master_nodes: 3 # # For more information, see the documentation at: # # # ---------------------------------- Various ----------------------------------- # # Disable starting multiple nodes on a single system: # # node.max_local_storage_nodes: 1 # # Require explicit names when deleting indices: # # action.destructive_requires_name: true
