配置详解

# ---------------------------------- Cluster （集群配置）-----------------------------------
#
# cluster.name: my-application   （自定义集群名称，相同集群该名称相同  my-application）
#
# ------------------------------------ Node ------------------------------------
#
 node.name: node-1     （当前节点名称，同一个集群中不能重复）

#
# Add custom attributes to the node:
#
# node.rack: r1
#
# ----------------------------------- Paths （数据，日志路径配合）------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
 path.data: /home/yang/elasticsearch-2.2.0/data  (数据存储路径，支持多路径)
#
# Path to log files:
#
 path.logs: /home/yang/elasticsearch-2.2.0/logs  （日志文件存储路径）
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
# bootstrap.mlockall: true   （是否锁住内存，指长期占用该内存，不产生内存交换，防止内存交换导致性能降低，配合内存设置使用）
#
# 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（网络配置） -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
# network.host: 192.168.0.1      （IP地址，url访问的ip）
#
# Set a custom port for HTTP:
#
# http.port: 9200       （http访问端口）
#
# For more information, see the documentation at:
# <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html>
#
# --------------------------------- Discovery （节点发现配置）----------------------------------
#
# 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"]    （初始主节点列表，默认启动是按照这个初始化master节点）
#
# Prevent the "split brain" by configuring the majority of nodes (total number of nodes / 2 + 1):
#
# discovery.zen.minimum_master_nodes: 3（集群中主节点数，默认 节点数/2 + 1）
#
# For more information, see the documentation at:
# <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-discovery.html>
#
# ---------------------------------- Gateway-------------------------
#
# Block initial recovery after a full cluster restart until N nodes are started:
#
# gateway.recover_after_nodes: 3   (n个节点启动后开始数据恢复)
#
# For more information, see the documentation at:
# <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-gateway.html>
#
# ---------------------------------- Various -----------------------------------
#
# Disable starting multiple nodes on a single system:
#
# node.max_local_storage_nodes: 1  （禁用多节点从同一个位置启动）
#
# Require explicit names when deleting indices:
#
# action.destructive_requires_name: true  （设置是否可以通过正则或者_all删除或者关闭索引）
