配置詳解

# ---------------------------------- Cluster （集群配置）-----------------------------------
#
# cluster.name: my-application   （自定義集群名稱，相同集群該名稱相同  my-application）
#
# ------------------------------------ Node ------------------------------------
#
 node.name: node-1     （當前節點名稱，同一個集群中不能重復）

#
# Add custom attributes to the node:
#
# node.rack: r1
#
# ----------------------------------- Paths （數據，日志路徑配合）------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
 path.data: /home/yang/elasticsearch-2.2.0/data  (數據存儲路徑，支持多路徑)
#
# Path to log files:
#
 path.logs: /home/yang/elasticsearch-2.2.0/logs  （日志文件存儲路徑）
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
# bootstrap.mlockall: true   （是否鎖住內存，指長期占用該內存，不產生內存交換，防止內存交換導致性能降低，配合內存設置使用）
#
# 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（網絡配置） -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
# network.host: 192.168.0.1      （IP地址，url訪問的ip）
#
# Set a custom port for HTTP:
#
# http.port: 9200       （http訪問端口）
#
# For more information, see the documentation at:
# <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html>
#
# --------------------------------- Discovery （節點發現配置）----------------------------------
#
# 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"]    （初始主節點列表，默認啟動是按照這個初始化master節點）
#
# Prevent the "split brain" by configuring the majority of nodes (total number of nodes / 2 + 1):
#
# discovery.zen.minimum_master_nodes: 3（集群中可以知道其他n個有master自個節點，默認 節點數/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個節點啟動后開始數據恢復)
#
# 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  （禁用多節點從同一個位置啟動）
#
# Require explicit names when deleting indices:
#
# action.destructive_requires_name: true  （設置是否可以通過正則或者_all刪除或者關閉索引）
