在生产环境中，强烈建议elasticsearch.yml中的path.data和path.logs设置为$ES_HOME之外的位置。
默认情况下，Docker、Debian和RPM安装会将数据和日志写入$ES_HOME之外的位置。
---------------------------------- Cluster -----------------------------------
Use a descriptive name for your cluster:
给集群取名字
cluster.name: elasticClusterName
------------------------------------ Node ------------------------------------
Use a descriptive name for the node:
给 当前ElasticSearch 节点取名字
node.name: node-1
node.master: true
node.data: true
node.ingest: false
当前 节点 在 集群中的角色
node.roles: [master,data,remote_cluster_client,ingest,ml,transform]
node.roles: {{$node_roles}}
----------------------------------- Paths ------------------------------------
Path to directory where to store the data (separate multiple locations by comma):
path.data: data
Path to log files:
设置 日志 存放地址
path.logs: /path/to/logs
----------------------------------- Memory -----------------------------------
Lock the memory on startup:
bootstrap.memory_lock: true
---------------------------------- Network -----------------------------------
Set the bind address to a specific IP (IPv4 or IPv6):
节点绑定 主机，0.0.0.0代表允许所有IP访问
network.host: 0.0.0.0
节点暴露的地址，elasticSearch 对外暴露的IP地址，即安装本机的地址
network.publish_host: XXX_IP
Set a custom port for HTTP:
对外暴露的端口
http.port: 9200
Set a custom port for TCP:
数据交互的 端口
transport.port: 9300
ingest.geoip.downloader.enabled: false
--------------------------------- Discovery ----------------------------------
Pass an initial list of hosts to perform discovery when this node is started:
集群 地址集合,所有安装了 elastic search 的地址
discovery.seed_hosts: ["XXX_IP1:9300","XXX_IP2:9300","XXX_IP3:9300"]
Bootstrap the cluster using an initial set of master-eligible nodes:
集群节点 名称 集合
cluster.initial_master_nodes: ["node-1","node-2","node-3"]
---------------------------------- Various -----------------------------------
Allow creating indices automatically:
action.auto_create_index: true
Require explicit names when deleting indices:
action.destructive_requires_name: true
xpack.security.audit.enabled: true
xpack.ml.enabled: false
Set to false to disable Watcher:
xpack.watcher.enabled: false
Security settings:
安全配 置
xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true
xpack.security.transport.ssl.verification_mode: certificate
xpack.security.transport.ssl.keystore.path: /app/elasticsearch/1/config/elastic-certificates.p12
xpack.security.transport.ssl.truststore.path: /app/elasticsearch/1/config/elastic-certificates.p12
