docker容器内elasticsearch安装

2023-10-09 14:05:22

一、elasticsearch 安装

docker 启动ES: docker run -d --name es2 -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" f29a1ee41030

docker 安装中文分词器

docker exec -it es /bin/bash

elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.6.2/elasticsearch-analysis-ik-7.6.2.zip

重启容器

docker restart es

二、elasticsearch7 设置xpack账号密码---整合springboot

1、进入容器&打开文件

docker exec -it es /bin/bash或 docker exec -it es bash

cd config

vi elasticsearch.yml

2、编辑文件

http.cors.enabled: true

http.cors.allow-origin: "*"

http.cors.allow-headers: Authorization

xpack.security.enabled: true

xpack.security.transport.ssl.enabled: true

记得重启 es

3、设置密码

cd bin

elasticsearch-setup-passwords interactive

4、退出&重启

exit

docker restart es

5、进入kibana容器中&打开文件

docker exec -it kibana /bin/bash

cd config

vi kibana.yml

配置：

server.name: kibana

server.host: "0.0.0.0"

elasticsearch.hosts: [ "http://{IpAddress}:9200" ]

monitoring.ui.container.elasticsearch.enabled: true

elasticsearch.username: "elastic"

elasticsearch.password: "password"

i18n.locale: "zh-CN"

查看es容器的ip地址

docker inspect --format='{{.NetworkSettings.IPAddress}}' es

三、elasticsearch第一次访问ES服务器超时

elasticsearch 放置一段时间后报30,000 milliseconds timeout on connection http-ou tgoing-2 [ACTIVE]

长时间停止ES访问后，与es服务器建立的HTTP连接死掉，需要重新建立连接

builder.setHttpClientConfigCallback(httpClientBuilder -> {

httpClientBuilder.setMaxConnTotal(MAX_CONN_TOTAL);

httpClientBuilder.setMaxConnPerRoute(MAX_CONN_PER_ROUTE);

httpClientBuilder.setKeepAliveStrategy((response, context) -> Duration.ofMinutes(5).toMillis());

httpClientBuilder.disableAuthCaching();

httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider);

return httpClientBuilder;

});

增加：
httpClientBuilder.setKeepAliveStrategy((response, context) -> Duration.ofMinutes(5).toMillis());
配置，保持client 每 5分钟发送数据保持http存活

或者

@Configuration

public class ElasticSearchConfig {

@Value("${spring.elasticsearch.cluster-nodes}")

private String hostname;

@Value("${spring.elasticsearch.cluster-port}")

private int port;

@Value("${spring.elasticsearch.username}")

private String userName;

@Value("${spring.elasticsearch.password}")

private String password;

// @Bean

// public RestHighLevelClient restHighLevelClient() {

// RestHighLevelClient client = new RestHighLevelClient(

// RestClient.builder(new HttpHost("47.113.206.200", 9200, "http")));

// return client;

// }

@Bean

public RestHighLevelClient restHighLevelClient() {

/* 用户认证对象 */

final CredentialsProvider credentialsProvider = new BasicCredentialsProvider();

/* 设置账号密码 */

credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(userName, password));

/* 创建rest client对象 */

RestClientBuilder builder = RestClient.builder(new HttpHost(hostname, port))

.setHttpClientConfigCallback(new RestClientBuilder.HttpClientConfigCallback() {

@Override

public HttpAsyncClientBuilder customizeHttpClient(HttpAsyncClientBuilder httpAsyncClientBuilder) {

// elasticsearch第一次访问ES服务器超时,保持client 每 5分钟发送数据保持http存活

httpAsyncClientBuilder

.setKeepAliveStrategy((response, context) -> Duration.ofMinutes(5).toMillis());

return httpAsyncClientBuilder.setDefaultCredentialsProvider(credentialsProvider);

}

});

RestHighLevelClient client = new RestHighLevelClient(builder);

return client;

}

四、elasticsearch中max_result_window有上限限制

PUT index/_settings

{

"index":{

"max_result_window":100000000

}

Elasticsearch 查询10000条限制与totalhits值最大10000的解决

SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder().trackTotalHits(true);
