Elasticsearch下载

ElasticSearch是基于lucence开发的，运行需要java jdk支持。
由于ElasticSearch 5.x 往后依赖于JDK 1.8的，需要下载JDK 1.8或者更高版本。
JDK的下载、安装和环境配置教程(2021年，win10)

Elasticsearch安装

下载好压缩包后分别解压两份，命名随意，路径随意
在这里插入图片描述

Elasticsearch.yml修改

首先是主节点，打开elasticsearch.yml
在这里插入图片描述

# ======================== 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:
#
# 集群名字,需要在同一个集群下的节点需要保持一致
cluster.name: my-elasticsearch
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
# 节点名字
node.name: master
#
# 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 -----------------------------------
#
# By default Elasticsearch is only accessible on localhost. Set a different
# address here to expose this node on the network:
#
# 设置其它节点和该节点交互的ip地址，如果不设置它会自动判断，值必须是个真实的ip地址。
network.host: 127.0.0.1
#
# By default Elasticsearch listens for HTTP traffic on the first free port it
# finds starting at 9200. Set a specific HTTP port here:
#
# 设置是否压缩tcp传输时的数据，默认为false，不压缩。
http.port: 9200
# 这个参数是用来同时设置bind_host和publish_host上面两个参数。
transport.tcp.port: 9300
#
# 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: ["127.0.0.1:9300", "127.0.0.1:8300","127.0.0.1:7300"]
#
# Bootstrap the cluster using an initial set of master-eligible nodes:
#
cluster.initial_master_nodes: ["127.0.0.1:9300", "127.0.0.1:8300","127.0.0.1:7300"]
#
# For more information, consult the discovery and cluster formation module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Require explicit names when deleting indices:
#
#action.destructive_requires_name: true
# head插件可以访问es
http.cors.enabled: true
http.cors.allow-origin: "*"

二者配置的区别只在http.port，transport.tcp.port和node.name上

配置好后依次打开节点elasticsearch.bat
在这里插入图片描述
出现started即打开成功

启动之后在浏览器输入http://localhost:9200/_cat/nodes验证一下
