## 结果
From:https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/elasticsearch.rb
Config:  /usr/local/etc/elasticsearch/

## 通过brew安装的es的yml文件，路径：/usr/local/etc/elasticsearch/
cluster.name: elasticsearch_brew
## 通过官网下载的es里的yml文件，路径：~/software/es/es-a/elasticsearch-8.0.1/config
cluster.name: my-application

# ======================== 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: cyx-application
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: node-1
# 是否有资格选举为主节点
node.master: true
# 是否存储数据
node.data: true
# 最大集群节点数
node.max_local_storage_nodes: 3
#
# 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: /Users/yuxichen/software/es/es-a/data
#
# Path to log files:
#
path.logs: /Users/yuxichen/software/es/es-a/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 -----------------------------------
#
# By default Elasticsearch is only accessible on localhost. Set a different
# address here to expose this node on the network:
#
#network.host: 192.168.0.1
#
# By default Elasticsearch listens for HTTP traffic on the first free port it
# finds starting at 9200. Set a specific HTTP port here:
# 端口号
http.port: 9201
# 内部节点之间沟通端口
transport.tcp.port: 9500
#
# 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]"]
# 候选主节点地址
#
discovery.seed_hosts: ["127.0.0.1:9300", "127.0.0.1:9400"]
#
# 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.
#
# ---------------------------------- Various -----------------------------------
#
# Allow wildcard deletion of indices:
#
#action.destructive_requires_name: false
