# ======================== 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:

# multi node configuration
cluster.name: exceptionless
action.destructive_requires_name: trueaction.auto_create_index: .security,.monitoring*,.watches,.triggered_watches,.watcher-history*#bootstrap.memory_lock: true#
# ------------------------------------ Node ------------------------------------#
# Use a descriptive name for the node:
#
node.name: p2_es_node_03

#
# 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: /path/to/data
#
# Path to log files:
#
#path.logs: /path/to/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#
# 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: 3#
# 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# 启用跨域
#Enable CORS in elasticsearch
http.cors.enabled: truehttp.cors.allow-origin: "*"# 集群配置
# 这个配置限制了单机上可以开启的ES存储实例的个数,当我们需要单机多实例，则需要把这个配置赋值2，或者更高。
node.max_local_storage_nodes: 1#设置这个集群中节点的数量，默认为2，一旦这N个节点启动，就会立即进行数据恢复。
gateway.expected_nodes: 3#设置这个参数来保证集群中的节点可以知道其它N个有master资格的节点。默认为1，对于大的集群来说，可以设置大一点的值（2-4）
discovery.zen.minimum_master_nodes: 2#设置集群中master节点的初始列表，可以通过这些节点来自动发现新加入集群的节点。
discovery.zen.ping.unicast.hosts: ["10.255.131.162","10.255.131.163","10.255.131.164"]
#network.bind_host: [ '_site_', '_local_' ]
#network.publish_host: '_site_'

## JVM configuration

################################################################
## IMPORTANT: JVM heap size
################################################################
##
## You should always set the min and max JVM heap
## size to the same value. For example, to set
## the heap to 4 GB, set:
##
## -Xms4g
## -Xmx4g
##
## See https://www.elastic.co/guide/en/elasticsearch/reference/current/heap-size.html## for more information
##
################################################################

# Xms represents the initial size of total heap space
# Xmx represents the maximum size of total heap space-Xms4g-Xmx4g
