ES之master机器配置elasticsearch.yml

# ======================== 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:
#配置集群名称，默认elasticsearch
cluster.name: "array-es-cluster"
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#配置节点名称
node.name: "master"
#
# Add custom attributes to the node:
#每个节点都可以定义一些与之关联的通用属性，用于后期集群进行碎片分配时的过滤
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#分配给当前节点的索引数据所在的位置
path.data: /data/apps/elasticsearch-7.9.0/data
#
# Path to log files:
#日志文件所在位置
path.logs: /data/apps/elasticsearch-7.9.0/logs
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
## 锁住内存，不被使用到交换分区去
#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: "10.241.42.41"
#
# 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]"]
#
#Elasticsearch7新增参数，写入候选主节点的设备地址，来开启服务时就可以被选为主节点
discovery.seed_hosts: ["10.241.42.41:9300", "10.241.42.165:9300"]
#
# Bootstrap the cluster using an initial set of master-eligible nodes:
#Elasticsearch7新增参数，写入候选主节点的设备地址，来开启服务时就可以被选为主节点
cluster.initial_master_nodes: ["master"]

# 主节点相关配置
node.master: true
node.data: false
node.ingest: false
node.ml: false
cluster.remote.connect: false

# 跨域
http.cors.enabled: true
http.cors.allow-origin: "*"

# x-head 访问配置
http.cors.allow-headers: Authorization,X-Requested-With,Content-Length,Content-Type

#security安全认证,开启xpack认证机制
#xpack.security.enabled: true
#xpack.security.transport.ssl.enabled: true

# 配置ssl和CA证书配置
#xpack.ssl.key: elasticsearch/elasticsearch.key
#xpack.ssl.certificate: elasticsearch/elasticsearch.crt
#xpack.ssl.certificate_authorities: ca/ca.crt

# 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:
#允许在N个节点启动后恢复过程
gateway.recover_after_nodes: 2
#
# For more information, consult the gateway module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Require explicit names when deleting indices:
#设置是否可以通过正则或者_all删除或者关闭索引，默认false 允许 可设置true不允许
#action.destructive_requires_name: true
