Elasticsearch Elasticsearch Configuration Static Elasticsearch Settings
Example
Elasticsearch uses a YAML (Yet Another Markup Language) configuration file that can be found inside the default Elasticsearch directory (RPM and DEB installs change this location amongst other things).
You can set basic settings in config/elasticsearch.yml:
# Change the cluster name. All nodes in the same cluster must use the same name!
cluster.name: my_cluster_name
# Set the node's name using the hostname, which is an environment variable!
# This is a convenient way to uniquely set it per machine without having to make
# a unique configuration file per node.
node.name: ${HOSTNAME}
# ALL nodes should set this setting, regardless of node type
path.data: /path/to/store/data
# This is a both a master and data node (defaults)
node.master: true
node.data: true
# This tells Elasticsearch to bind all sockets to only be available
# at localhost (default)
network.host: _local_
