简介
Elasticsearch 是一个实时的分布式搜索分析引擎， 它能让你以一个之前从未有过的速度和规模，去探索你的数据。 它被用作全文检索、结构化搜索、分析以及这三个功能的组合。
下载ElasticSearch
最新版下载地址：https://www.elastic.co/downloads/elasticsearch
为了配合中文分词插件的版本，这里我下载的是elasticsearch-8.2.3
https://www.elastic.co/cn/downloads/past-releases/elasticsearch-8-2-3
https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.2.3-windows-x86_64.zip
安装ElasticSearch
在windows下的ElasticSearch是一个压缩包，所有的命令都是bat批处理文件。
解压缩以后执行bin目录里面的批处理文件就可以运行了
启动ElasticSearch
进入bin目录执行elasticsearch.bat
$ cd D:\elasticsearch-8.2.3\bin
$ elasticsearch.bat
第一次访问的时候注意看一下默认的账号和密码

-> Configure Kibana to use this cluster:
* Run Kibana and click the configuration link in the terminal when Kibana starts.
* Copy the following enrollment token and paste it into Kibana in your browser (valid for the next 30 minutes):

-> Configure other nodes to join this cluster:
* On this node:
- Create an enrollment token with `bin/elasticsearch-create-enrollment-token -s node`.
- Uncomment the transport.host setting at the end of config/elasticsearch.yml.
- Restart Elasticsearch.
* On other nodes:
- Start Elasticsearch with `bin/elasticsearch --enrollment-token <token>`, using the enrollment token that you generated.

设置账号和密码
先不要关闭elasticsearch，然后新开一个CMD窗口，执行命令
$ elasticsearch-setup-passwords.bat interactive

安装中文分词插件-方式1
首先下载和elasticsearch版本对应的插件:
https://github.com/medcl/elasticsearch-analysis-ik/releases
大概4.3m左右，然后复制到bin目录。
D:\elasticsearch-8.2.3\bin
$ elasticsearch-plugin install elasticsearch-analysis-ik-8.2.3.zip
运行过程
D:\elasticsearch-8.2.3\bin
$ elasticsearch-plugin install elasticsearch-analysis-ik-8.2.3.zip

安装中文分词插件-方式2
1.直接解压缩到\plugins目录中
$ cd D:\elasticsearch-8.3.2\plugins
D:\elasticsearch-8.3.2\plugins
$ ls
elasticsearch-analysis-ik-8.2.3/
2.ik分词器的plugin-descriptor.properties
# 'description': simple summary of the plugin
description=IK Analyzer for Elasticsearch
#
# 'version': plugin's version
version=8.3.2
#
# 'name': the plugin name
name=analysis-ik
#
# 'classname': the name of the class to load, fully-qualified.
classname=org.elasticsearch.plugin.analysis.ik.AnalysisIkPlugin
#
# 'java.version' version of java the code is built against
# use the system property java.specification.version
# version string must be a sequence of nonnegative decimal integers
# separated by "."'s and may have leading zeros
java.version=1.8
#
# 'elasticsearch.version' version of elasticsearch compiled against
# You will have to release a new version of the plugin for each new
# elasticsearch release. This version is checked when the plugin
# is loaded so Elasticsearch will refuse to start in the presence of
# plugins with the incorrect elasticsearch.version.
elasticsearch.version=8.3.2
主要修改version=8.3.2和elasticsearch.version=8.3.2
提示：
我用的最新的ElasticSearch8.3.2版本，ik分词器最新的版本8.2.3,版本没有跟上，最好es-ik分词插件版本要和es安装的版本对应。
