windows搭建elasticsearch集群+kibana并整合javawindow环境下的伪集群，三台实例。修改

环境准备
环境搭建
整合java代码

1.环境准备

版本说明

名称	版本
elasticsearch	7.8.0
kibana	7.8.0
spring-boot-starter-data-elasticsearch	2.3.1.RELEASE
jdk	1.8

注意：elasticsearch 7.8 自带JDK11，也可以设置jdk

环境说明

window环境下的伪集群，三台实例。

名称	http端口	tcp端口
第一台	9201	9300
第二台	9202	9400
第三台	9203	9500

kibana 使用默认

软件下载

ElasticSearch 下载地址

Kibana 下载地址

最好下载zip包

2.搭建Elasticsearch集群和Kibana

解压elasticsearch-7.8.0-windows-x86_64

1.根目录创建data 文件夹

2.配置文件elasticsearch.yml

#集群名称
cluster.name: elasticsearch-cluster
#节点名称
node.name: node-1
#是不是有资格主节点
node.master: true
#是否存储数据
node.data: true
#最大集群节点数
node.max_local_storage_nodes: 3
#数据
path.data: C:/software/elasticsearch/elasticsearch-7.8.0-1/data
#日志
path.logs: C:/software/elasticsearch/elasticsearch-7.8.0-1/logs
#配置ip （如果需要外网访问，配置外网ip）
network.host: 127.0.0.1
http.port: 9201
transport.tcp.port: 9300
#其他两个节点地址（如果需要外网访问，配置外网ip）
discovery.seed_hosts: ["localhost:9300", "localhost:9400"]
#其他两个节点
cluster.initial_master_nodes: ["node-1", "node-2"，"node-3"]

3.完整配置文件

#集群名称
cluster.name: elasticsearch-cluster
#节点名称
node.name: node-1
#是不是有资格主节点
node.master: true
#是否存储数据
node.data: true
#最大集群节点数
node.max_local_storage_nodes: 3
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
path.data: C:/software/elasticsearch/elasticsearch-7.8.0-3/data
#
# Path to log files:
#
path.logs: C:/software/elasticsearch/elasticsearch-7.8.0-3/logs
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
#bootstrap.memory_lock: true
#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
network.host: 127.0.0.1
#
# Set a custom port for HTTP:
#
http.port: 9201
#
# For more information, consult the network module documentation.
transport.tcp.port: 9300
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when this node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
discovery.seed_hosts: ["localhost:9300", "localhost:9400"，"localhost:9500"]
#
# Bootstrap the cluster using an initial set of master-eligible nodes:
#
cluster.initial_master_nodes: ["node-1", "node-2", "node-3"]
#
# For more information, consult the discovery and cluster formation module documentation.
#
# ---------------------------------- Gateway -----------------------------------
#
# Block initial recovery after a full cluster restart until N nodes are started:
#
#gateway.recover_after_nodes: 3
#
# For more information, consult the gateway module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Require explicit names when deleting indices:
#
#action.destructive_requires_name: true
#配置跨域
bootstrap.system_call_filter: false
http.cors.allow-origin: "*"
http.cors.enabled: true
http.cors.allow-headers : X-Requested-With,X-Auth-Token,Content-Type,Content-Length,Authorization
http.cors.allow-credentials: true
#开启x-pack验证
#xpack.security.enabled: true
#是否开启服务端 SSL 证书
#xpack.license.self_generated.type: basic
#xpack.security.transport.ssl.enabled: true
#xpack.security.transport.ssl.verification_mode: certificate
#xpack.security.transport.ssl.keystore.path: certs/elastic-certificates.p12
#xpack.security.transport.ssl.truststore.path: certs/elastic-certificates.p12

注意: 配置这里有坑，配置为yml文件，["node-1", "node-2", "node-3"] 注意前面有空格，有空格，有空格！！！， xpack.security.enabled: true 该配置如需要密码验证才打开

如果开启x-pack认证遇到报DecoderException: javax.net.ssl.SSLHandshakeException: No available authentic异常

4.启动elasticsearch集群

创建其他两个节点

复制三个文件夹 elasticsearch-7.8.0-1 ，elasticsearch-7.8.0-2 ，elasticsearch-7.8.0-3

修改对对应elasticsearch.yml配置文件分别有端口，tcp端口

分别运行三个elasticsearch.bat

集群验证 http://localhost:9201,http://localhost:9202

查看集群 http://localhost:9201/_cat/health?v 状态为green

如果需要设置密码

打开三台配置， xpack.security.enabled: true

修改配置后重启集群，再进入http://localhost:9202 则需要密码了。

设置密码 cmd 进入第一台的bin目录

运行 elasticsearch-setup-passwords.bat interactive 自定义密码或者运行 elasticsearch-setup-passwords.bat auto 自动生成密码

5.kibana安装

解压zip，修改配置文件

server.port: 5601
server.host: "127.0.0.1"
server.name: "your-hostname"
elasticsearch.hosts: ["http://127.0.0.1:9202"]
elasticsearch.username: "elastic"
elasticsearch.password: "123456"

配置elasticsearch的master节点和密码

启动kibana ./bin/kibana.bat

启动稍微有点慢，耐心等待

http://127.0.0.1:5601 访问kibana界面

另外附上一个启动脚本

    @echo off
    title elasticsearch-cluster
    set JAVA_HOME=C:\Program Files\Java\jdk1.8.0_181
    set PATH=%JAVA_HOME%\bin;
    cd /d C:\software\elasticsearch\elasticsearch-7.8.0-1\bin
    start "elasticsearch-cluster:node-1" elasticsearch.bat
    cd /d C:\software\elasticsearch\elasticsearch-7.8.0-2\bin
    start "elasticsearch-cluster:node-2" elasticsearch.bat
    cd /d C:\software\elasticsearch\kibana-7.8.0-windows-x86_64\bin
    start "kibana" kibana.bat

创建后缀为 start.bat文件，修改路径，点击启动start.bat 就不用一个一个去启动了

elasticsearch支持SQL了，kibana中的devtools界面查询

POST /_sql?format=txt
{
  "query": "SELECT id,district,province,street,streetNumber FROM address_components LIMIT 10"
}

用起来很方便的，谁用谁知道

3.整合JAVA

maven配置

       <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
            <version>2.3.1.RELEASE</version>
        </dependency>

application.yml文件

 spring:
  elasticsearch:
    rest:
      uris:
        - 127.0.0.1:9201
        - 127.0.0.1:9202
        - 127.0.0.1:9203
      username: elastic
      password: 123456

Java实体类对应ES的文档索引

@Document(indexName = "address_components")
@Data
public class AddressComponents {
    private String id;
    /**
     * 城市
     */
    private String city;
    /**
     * 区县
     */
    private String district;
    /**
     * 省份
     */
    private String province;
    /**
     * 路
     */
    private String street;
    /**
     * 号
     */
    private String streetNumber;
   }

Java对应操作ES JPA

public interface AddressComponentsResponsitory extends ElasticsearchRepository<AddressComponents, String> {
}

Java对应操作ES 调用

增加/修改
responsitory.save(addressComponents);
查询单个
responsitory.findById(id);

Java对应操作ES 调用（高级查询）

注入操作类

	 @Autowired
    private ElasticsearchRestTemplate restTemplate;

    NativeSearchQuery searchQuery = new NativeSearchQueryBuilder()
            //条件查询
            .withQuery(QueryBuilders.termQuery("userId", userId))
            //排序
            .withSort(SortBuilders.fieldSort("updateTime").order(SortOrder.DESC))
            .build();
        SearchHits<TicketEs> search = this.restTemplate.search(searchQuery, TicketEs.class);
        List<TicketEs> list = (List<TicketEs>) SearchHitSupport.unwrapSearchHits(search);
