[TOC] ## 一、下載 下載地址：[https://www.elastic.co/cn/downloads/elasticsearch](https://www.elastic.co/cn/downloads/elasticsearch)  獲取歷史版本：  ## 二、安裝 ### 2. 配置xpack  #### 2.1. 生成證書 ``` bin/elasticsearch-certutil cert -out config/elastic-certificates.p12 -pass "" ``` #### 2.2. 修改配置 ``` vim config/elasticsearch.yml ``` 修改config目錄下elasticsearch.yml文件，在最后新增以下參數 ``` xpack.security.enabled: true xpack.security.transport.ssl.enabled: true xpack.security.transport.ssl.verification_mode: certificate xpack.security.transport.ssl.keystore.path: elastic-certificates.p12 xpack.security.transport.ssl.truststore.path: elastic-certificates.p12 ``` 配置elasticsearch.yml ``` cluster.name: my-es network.host: 0.0.0.0 node.name: node-1 cluster.initial_master_nodes: ["node-1"] http.cors.enabled: true http.cors.allow-origin: "*" bootstrap.memory_lock: false bootstrap.system_call_filter: false xpack.security.enabled: true xpack.security.transport.ssl.enabled: true xpack.security.transport.ssl.verification_mode: certificate xpack.security.transport.ssl.keystore.path: elastic-certificates.p12 xpack.security.transport.ssl.truststore.path: elastic-certificates.p12 ``` ## 三、啟動 ``` bin/elasticsearch ``` > 后臺運行：bin/elasticsearch -d ## 四、初始化密碼 兩種方式二選一 ### 4.1. 自動生成密碼 ``` bin/elasticsearch-setup-passwords auto ``` ### 4.2. 手動設置密碼 ``` bin/elasticsearch-setup-passwords?interactive ``` > 【重要】記錄密碼，很多地方需要驗證密碼。如：logstash，kibana。 ``` Changed password for user apm_system PASSWORD apm\_system = vKqf8FtzpUqPDrYfbsjt Changed password for user kibana_system PASSWORD kibana_system = 45CnPubkY740mul0BGst Changed password for user kibana PASSWORD kibana = 45CnPubkY740mul0BGst Changed password for user logstash_system PASSWORD logstash_system = KIUsb7e2cJePAWH5KW1t Changed password for user beats_system PASSWORD beats_system = zAnlSRyBEWJ1oOyUjxSK Changed password for user remote_monitoring_user PASSWORD remote_monitoring_user = K1YDZxvqURqIVylvUq0J Changed password for user elastic PASSWORD elastic = 7kgH0ARRpwLbhrdCTvrO ``` ## 五、IK分詞器 查詢數據，都是使用的默認的分詞器，分詞效果不太理想，會把text的字段分成一個一個漢字，然后搜索的時候也會把搜索的句子進行分詞，所以這里就需要更加智能的分詞器IK分詞器了 ### 5.1. 下載 下載地址：[https://github.com/medcl/elasticsearch-analysis-ik/releases](https://github.com/medcl/elasticsearch-analysis-ik/releases) > 這里你需要根據你的**Es的版本來下載對應版本的IK** ### 5.2. 將解壓文件復制到 es的安裝目錄/plugin/ik下面即可  ### 5.3. 重啟es并檢查插件是否安裝成功 [http://localhost:9200/\_cat/plugins](http://localhost:9200/_cat/plugins)  ## 六、訪問 1. 驗證密碼 [http://localhost:9200](http://localhost:9200) 打開瀏覽器，輸入我們的elasticsearch的網址，比如本地的[http://localhost:9200/](http://localhost:9200/)?，然后會彈出一個輸入框，讓我們輸入賬號和密碼   2. 查看索引 [http://localhost:9200/\_cat/indices?v](http://localhost:9200/_cat/indices?v)  3. 查看插件 [http://localhost:9200/\_cat/plugins](http://localhost:9200/_cat/plugins)  4. 查看狀態 [http://localhost:9200/\_cluster/health?pretty=true](http://localhost:9200/_cluster/health?pretty=true)
