下载elasticsearch和kibana安装包

es和kibana官网下载地址

解压安装

安装 elasticsearch

解压后点击elasticsearch-7.10.0\bin\elasticsearch.bat运行成功后,输入http://120.0.0.1:9200,可以访问说明ES启动成功

安装 kibana

点击kibana-7.10.0-windows-x86_64\bin\kibana.bat 启动成功后,输入http://localhost:5601/即可进入kibana

配置登录账号密码

ealsticsearch设置账号密码

打开config/ealsticsearch.yml增加开启密码配置,然后重启ealsticsearch

xpack.security.enabled: true
xpack.license.self_generated.type: basic
xpack.security.transport.ssl.enabled: true

输入.\bin\elasticsearch-setup-passwords.bat interactive设置密码,这里有一些ES内置的账号密码,比如kibana_system这个账号密码需要配置到kibana.yml中,这里要记一下,本地测试我都设置成123456好了,生产环境密码强度要设置大点,不可用简单密码
PS D:\service\ES\elasticsearch-7.10.0> .\bin\elasticsearch-setup-passwords.bat interactive
future versions of Elasticsearch will require Java 11; your Java version from [C:\Program Files\Java\jdk1.8.0_191\jre] does not meet this requirement

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]
​
再次打开http://localhost:9200,输入账号elastic账号,密码123456,登录成功说明密码设置成功;
 

 

kibana中设置es账号密码

打开kibana-7.10.0-windows-x86_64\config\kiban.yml设置账号密码后,重启kibana,再次输入localhost:5601就可以使用账号密码登录了

elasticsearch.hosts: ["http://localhost:9200"]
elasticsearch.username: "kibana_system"
elasticsearch.password: "123456"

导测试数据

使用Kiban创建索引并导入测试数据 ,点击kibandev Tools执行创建索引和插入数据

PUT /news
{
  "mappings": {
    "properties": {
      "id": {
        "type": "long"
      },
      "title": {
        "type": "text",
        "analyzer": "standard"
      },
      "tags": {
        "type": "keyword"
      },
      "read_count": {
        "type": "long"
      },
     "like_count": {
        "type": "long"
      },
     "comment_count": {
        "type": "long"
      },
      "rank": {
        "type": "double"
      },
      "location": {
          "type": "geo_point"
        },
      "pub_time": {
        "type": "date",
        "format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd HH:mm||yyyy-MM-dd||epoch_millis"
      }
    }
  }
}

POST _bulk
{"create": {"_index": "news", "_id": 1}}
{"comment_count":600,"id":1,"like_count":2000,"location":[118.55199,24.78144],"pub_time":"2023-07-29 09:47","rank":0.0,"read_count":10000,"tags":["台风","杜苏芮","福建"],"title":"台风“杜苏芮”登陆福建晋江 多部门多地全力应对"}
{"create": {"_index": "news", "_id": 2}}
{"comment_count":60,"id":2,"like_count":200,"location":[116.23128,40.22077],"pub_time":"2023-06-29 14:49:38","rank":0.0,"read_count":1000,"tags":["台风","杜苏芮","北京"],"title":"受台风“杜苏芮”影响 北京7月29日至8月1日将有强降雨"}
{"create": {"_index": "news", "_id": 3}}
{"comment_count":6,"id":3,"like_count":20,"location":[120.21201,30.208],"pub_time":"2020-07-29 14:49:38","rank":0.99,"read_count":100,"tags":["台风","杭州"],"title":"杭州解除台风蓝色预警信号"}

JAVA客户端连接

pom引入elasticsearch-rest-high-level-client

        <dependency>
            <groupId>org.elasticsearch.client</groupId>
            <artifactId>elasticsearch-rest-high-level-client</artifactId>
            <version>7.10.0</version>
        </dependency>

创建RestHighLevelClient并完成查询

   public static RestHighLevelClient esClient;

    static {
        CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
        credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials("elastic", "123456"));
        RestClientBuilder builder = RestClient.builder(new HttpHost("127.0.0.1", 9200))
                .setHttpClientConfigCallback(httpClientBuilder -> httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider));
        esClient = new RestHighLevelClient(builder);

    }
    public static Map<String, Object> getById(String index, String id) throws IOException {
        GetRequest request = new GetRequest(index, id);
        GetResponse getResponse = esClient.get(request, RequestOptions.DEFAULT);
        return  getResponse.getSourceAsMap();
    }
    public static void main(String[] args) throws IOException {
        var doc=getById("news","1");
        doc.forEach((k,v)-> System.out.println(k+":"+v));
    }

测试运行

测试运行通过,可完成查询
