一、ES證書申請

Register | Elastichttps://license.elastic.co/registration

• 郵箱下載授權文件是一個json格式 ,修改json文件的屬性，basic 基礎版本，platinum 白金版本,時間戳自行修改，年限自定義

• "type":"basic" 替換為 "type":"platinum"??

• "expiry_date_in_millis":"1765556390000"?

二、ES證書類型對比

訂閱 | Elastic Stack 產品和支持 | Elastic查看 Elastic Stack（Elasticsearch、Kibana、Beats 和 Logstash）就地部署、Elastic Cloud 和 Elastic Cloud Enterprise 的訂閱級別、定價和分級功能。https://www.elastic.co/cn/subscriptions

三、使用授權,進入到json 所在的文件目錄，執行以下命令

curl -XPOST -u elastic "http://127.0.0.1:9200/_xpack/license?acknowledge=true" -H "Content-Type: application/json" -d @xxxx.json Enter host password for user 'elastic': {"acknowledged":true,"license_status":"invalid"}

四、 修改用戶密碼

E:\elasticsearch-7.17.4-windows-x86_64\elasticsearch-7.17.4\bin>elasticsearch-setup-passwords interactive "warning: usage of JAVA_HOME is deprecated, use ES_JAVA_HOME" Future versions of Elasticsearch will require Java 11; your Java version from [C:\Program Files\Java\jdk1.8.0_181\jre] does not meet this requirement. Consider switching to a distribution of Elasticsearch with a bundled JDK. If you are already using a distribution with a bundled JDK, ensure the JAVA_HOME environment variable is not set. Initiating the setup of passwords for reserved users elastic,apm_system,kibana,kibana_system,logstash_system,beats_system,remote_monitoring_user. You will be prompted to enter passwords as the process progresses. Please confirm that you would like to continue [y/N]yEnter password for [elastic]: Reenter password for [elastic]: Enter password for [apm_system]: Reenter password for [apm_system]: Enter password for [kibana_system]: Reenter password for [kibana_system]: Enter password for [logstash_system]: Reenter password for [logstash_system]: Enter password for [beats_system]: Reenter password for [beats_system]: Enter password for [remote_monitoring_user]: Reenter password for [remote_monitoring_user]: Changed password for user [apm_system] Changed password for user [kibana_system] Changed password for user [kibana] Changed password for user [logstash_system] Changed password for user [beats_system] Changed password for user [remote_monitoring_user] Changed password for user [elastic]

五、替換jar包

聯系博主，取鉑金版jar包

六、修改spingboot的配置文件

spring:data:elasticsearch:repositories:enabled: truerest:uris: localhost:9200username: elasticpassword: xxxx

這種方式在沒有開啟安全策略以后，會一直報錯，401?ES status line [HTTP/1.1 401 Unauthorized]];

需要調整配置文件

spring:elasticsearch:password: xxxusername: elasticuris: [localhost:9200] curl -XPUT http://elastic:cfl,1997@127.0.0.1:9200/syslog/_settings -d "{\"number_of_replicas\": 0}" -H "Content-Type: application/json"
