（0.5）elasticsearch配置文件(基础)

【0】默认文件内容

#(1)cluster
cluster.name：集群名称     # 默认名称为 elasticsearch
cluster.initial_master_nodes：["node-1","node-2"]　　#分布式集群，初始化节点
gateway.recover_after_nodes：3                      #在整个集群重启后，阻止恢复访问，直到启动完 N 个节点位置（这里就是要3个节点及以上启动好之后才可以访问）

#(2)node
＃node.name：node-1         #默认为计算机名，但应该为节点起一个描述性名称
＃node.attr.rack：r1        #添加自定义的节点属性

#(3)path
path.data：/path/to/data   #数据文件路径，可以有多个路径，多个路径以 , 逗号分割
path.logs：/path/to/logs

#(4)memory
bootstrap.memory_lock：true   #在启动时锁定内存（锁定内存页）,确保将堆大小设置为可用内存的一半，并且在操作系统层面解开使用限制

#(5)network
network.host：192.168.0.1   #设置绑定地址：本机IP
network.host：0.0.0.0       #设置绑定地址：任意地址，建议设置这个，省事
http.port：9200             #设置绑定端口

#(6)discovery
#默认主机列表为 【127.0.0.1】，【::1】，也就是本机
discovery.seed_hosts：["host1","host2"]

#others
action.destructive_requires_name：true　　         #删除索引时，必须要提供具体的名称！

# ======================== 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: my-application
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
#node.name: node-1
#
# 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: 192.168.0.1
#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 this node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
#discovery.seed_hosts: ["host1", "host2"]
#
# Bootstrap the cluster using an initial set of master-eligible nodes:
#
#cluster.initial_master_nodes: ["node-1", "node-2"]
#
# 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
