ElasticSearch版本：7.7.1,其他版本号设置是一样的。用7.14版本有测试过。

配置#

修改es的配置文件：elasticsearch.yml，添加如下配置

xpack.security.enabled: true

xpack.license.self_generated.type: basic

xpack.security.transport.ssl.enabled: true

es的bin目录下，执行设置用户名和密码的命令

./elasticsearch-setup-passwords interactive

这里会设置六个账号的密码：elastic,apm_system,kibana,logstash_system,beats_system,remote_monitoring_user.

修改kibana的配置kibana.yml：

es修改密码的命令如下：

curl -H "Content-Type:application/json" -XPOST -u elastic 'http://192.168.140:9200/_xpack/security/user/elastic/_password' -d '{ "password" : "123456" }'

重启es和kibana

访问http://192.168.1.40:9200，需要输入账号密码才可以访问

访问：http://192.168.1.40:5601/

同样需要认证才可登陆，登陆账号密码为elastic/123456

java客户端连接#

需要与springdata es整合

RestHighLevelClient#

    @Bean

    public RestHighLevelClient restHighLevelClient() {

        final ClientConfiguration clientConfiguration = ClientConfiguration.builder()

                .connectedTo("192.168.1.40:9200")

                .withConnectTimeout(Duration.ofSeconds(5))

                .withSocketTimeout(Duration.ofSeconds(3))

                .withBasicAuth("elastic", "123456")

                .build();

        return RestClients.create(clientConfiguration).rest();

    }

SpringData ES配置#

spring:

  elasticsearch:

    rest:

      uris: "http://192.168.1.40:9200"

      read-timeout: "10s"

      username: "elastic"

      password: "123456"

      connection-timeout: "10s"
