# ======================== 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: estest
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: test1
#
# Add custom attributes to the node:
#
node.attr.rack: r1
node.master: true
node.data: true
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
path.data: data
#
# Path to log files:
#
path.logs: logs
#
# ----------------------------------- 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: 0.0.0.0
#
# Set a custom port for HTTP:
#
http.port: 9200
# 内部节点通信端口
transport.tcp.port: 9300
# 开启安全防护
http.cors.enabled: true
http.cors.allow-origin: /.*/
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when this node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
# 设置可参选master的节点
#discovery.seed_hosts: ["127.0.0.1:9300","127.0.0.1:9301","127.0.0.1:9302"]
discovery.seed_hosts: ["127.0.0.1", "[::1]"]
# ping超时时长,默认3S,适当修改,防止脑裂
discovery.zen.ping_timeout: 120s
client.transport.ping_timeout: 60s
http.cors.allow-headers: Authorization,X-Requested-With,Content-Length,Content-Type
#
# Bootstrap the cluster using an initial set of master-eligible nodes:
#
#cluster.initial_master_nodes: ["node-1", "node-2"]
cluster.initial_master_nodes: ["test1","test2","test3"]
#cluster.initial_master_nodes: ["127.0.0.1:9300","127.0.0.1:9301","127.0.0.1:9302"]
#
# For more information, consult the discovery and cluster formation 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
