簡介

Elasticsearch 是一個實(shí)時的分布式搜索分析引擎脱柱， 它能讓你以一個之前從未有過的速度和規(guī)模榨为，去探索你的數(shù)據(jù)。 它被用作全文檢索日川、結(jié)構(gòu)化搜索板壮、分析以及這三個功能的組合绰精。

下載ElasticSearch

最新版下載地址：https://www.elastic.co/downloads/elasticsearch

為了配合中文分詞插件的版本，這里我下載的是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

安裝ElasticSearch

在windows下的ElasticSearch是一個壓縮包卿樱，所有的命令都是bat批處理文件硫椰。

解壓縮以后執(zhí)行bin目錄里面的批處理文件就可以運(yùn)行了

啟動ElasticSearch

進(jìn)入bin目錄執(zhí)行elasticsearch.bat

    $ cd D:\elasticsearch-8.2.3\bin
    $ elasticsearch.bat

第一次訪問的時候注意看一下默認(rèn)的賬號和密碼

    --------------------------------------------------------------------------------------------------
    
    -> Elasticsearch security features have been automatically configured!
    -> Authentication is enabled and cluster connections are encrypted.

    ->  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.

訪問測試繁调，看到提示需要密碼萨蚕。

設(shè)置賬號和密碼

先不要關(guān)閉elasticsearch，然后新開一個CMD窗口蹄胰，執(zhí)行命令

安裝中文分詞插件-方式1

首先下載和elasticsearch版本對應(yīng)的插件:

https://github.com/medcl/elasticsearch-analysis-ik/releases

https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v8.2.3/elasticsearch-analysis-ik-8.2.3.zip

大概4.3m左右岳遥，然后復(fù)制到bin目錄。

D:\elasticsearch-8.2.3\bin
$ elasticsearch-plugin install elasticsearch-analysis-ik-8.2.3.zip

運(yùn)行過程

D:\elasticsearch-8.2.3\bin
$ elasticsearch-plugin install elasticsearch-analysis-ik-8.2.3.zip

ERROR: Unknown plugin elasticsearch-analysis-ik-8.2.3.zip

安裝中文分詞插件-方式2

1.直接解壓縮到\plugins目錄中

$ cd D:\elasticsearch-8.3.2\plugins

D:\elasticsearch-8.3.2\plugins
$ ls
elasticsearch-analysis-ik-8.2.3/

2.ik分詞器的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版本裕寨，ik分詞器最新的版本8.2.3,版本沒有跟上，最好es-ik分詞插件版本要和es安裝的版本對應(yīng)宾袜。
