ElasticSearch+Kibana设置用户名密码登陆

ElasticSearch版本：7.7.1

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

原生RestHighLevelClient配置

    @Bean
    public RestHighLevelClient restHighLevelClient() {

        final ClientConfiguration clientConfiguration = ClientConfiguration.builder()
                .connectedTo("192.168.1.40:9200")
                .withConnectTimeout(Duration.ofSeconds(10))
                .withSocketTimeout(Duration.ofSeconds(10))
                .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"
