es簡(jiǎn)介

Elastic官網(wǎng)

https://www.elastic.co/cn/

主要功能:

分布式搜索

數(shù)據(jù)分析

分組和聚合

es下載地址

https://www.elastic.co/cn/downloads/

linux安裝es

• 將下載的安裝包上傳導(dǎo)linux服務(wù)器,我的版本是elasticsearch-7.2.0-linux-x86_64.tar.gz
• 創(chuàng)建usr/local/soft/es目錄,將es解壓到這個(gè)目錄中
• 修改es的yum文件

node.name: node-1
// 這個(gè)很重要
http.host: 0.0.0.0
http.port: 9200

• 修改es的jvm.options

-Xms256M
-Xmx256M

• 創(chuàng)建新的用戶(hù)來(lái)啟動(dòng)es
• useradd esuser
• 賦予權(quán)限

chown -R esuser:esuser /usr/local/software/elasticsearch-7.2.0

• 切換到esuser用戶(hù)

su esuser

• 通過(guò)es用戶(hù)后臺(tái)啟動(dòng)es

sh elasticsearch -d

• 驗(yàn)證是否啟動(dòng)成功

curl -X GET "http://localhost:9200"

添加ik到es中

• 下載ik的版本必須和es版本對(duì)應(yīng)
• 將ik放到es的plugin目錄下進(jìn)行解壓

es重啟后會(huì)加載ik

es中新增索引post

curl -X PUT "localhost:9200/post" 

將分詞器修改成ik

• 關(guān)閉索引

POST post/_close

• 配置ik

PUT post/_settings
{
  "number_of_replicas": 0,
  "index":{
    "analysis.analyzer.default.type":"ik_max_word",
    "analysis.search_analyzer.default.type":"ik_smart"
  }
}

• 開(kāi)啟post索引

POST post/_open

創(chuàng)建es的mapping,根據(jù)自己的需求創(chuàng)建

curl --location --request PUT '787k.fun:9200/post/_mapping' \
--header 'Content-Type: application/json' \
--data-raw '{
    "properties": {
        "id": {
            "type": "integer"
        },
        "title": {
            "type": "text"
        },
        "content": {
            "type": "text"
        },
        "blogImg": {
            "type": "keyword"
        },
        "html_content": {
            "type": "keyword"
        },
        "authorId": {
            "type": "integer"
        },
        "authorName": {
            "type": "keyword"
        },
        "tag": {
            "type": "integer"
        },
        "type": {
            "type": "integer"
        },
        "status": {
            "type": "integer"
        },
        "commentCount": {
            "type": "integer"
        },
        "score": {
            "type": "double"
        },
        "created": {
            "type": "date"
        },
        "updated": {
            "type": "date"
        }
    }
}'

springboot集成es

• pom文件加入依賴(lài)

    
      org.elasticsearch.client
      elasticsearch-rest-high-level-client
      7.2.0
    
    
      org.elasticsearch
      elasticsearch
      7.2.0
    
    

• yum文件添加文件

elasticsearch.host=localhost
elasticsearch.port=9200
