下载elasticsearch和kibana安装包

原文连接：https://juejin.cn/post/7261262567304298554

elasticsearch官网下载比较慢，有时还打不开，可以通过https://elasticsearch.cn/download/下载，先找到对应的版本，最好使用迅雷下载，秒下的，我的下载速度可以达到40M/S

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

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"

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
