es集群搭建
#編寫compose.yml配置文件
#每個節(jié)點都創(chuàng)建一個elasticsearch.yml文件
用到的命令：
systemctl start docker
docker-compose up
compose.yml
es和kibana版本必須一樣
- environment:配置容器內(nèi)的環(huán)境變量
- networks:創(chuàng)建一個名為elastic的局域網(wǎng)，讓各節(jié)點以及kibana,es-head相互聯(lián)系

采用vmware安裝centos7來模擬服務器
-
采用NAT模式
-
centos7虛擬機配置靜態(tài)IP
用到的命令： -
cd /etc/sysconfig/network-scripts/
-
vi ifcfg-ens33 #未必是ens33,這和你的DEVICE名稱相同，以實際為準
-
配好后，記得systemctl restart network.service重啟一下網(wǎng)絡服務
虛擬機配置靜態(tài)ip：
- 必須要添加IPADDR,GATEWAY,DNS1三個配置，否則，虛擬機將無法訪問網(wǎng)絡
- GATAWAY和DNS1保持一致，與vmware的NAT網(wǎng)絡設置的值相同
- IPADDR前三位和GATAWAY一樣，最后一位隨意
- 具體值在此處查看
必須將IP設置為靜態(tài)IP，否則將無法用瀏覽器訪問！
springboot集成es
#引入依賴
#創(chuàng)建application.yml配置文件
#創(chuàng)建實體類，順便通過注解創(chuàng)建Index索引
#創(chuàng)建esUtil工具類
#創(chuàng)建啟動類和控制類
引入依賴

使用注解創(chuàng)建索引（和MyBatis類似）

import lombok.Data;
import org.springframework.data.annotation.Id;
import org.springframework.data.elasticsearch.annotations.Document;

@Data
@Document(indexName = "user",createIndex = true)
public class EsEntity {
@Id
@Field(type = FieldType.Auto)
private Long id;
@Field(type = FieldType.Text)
private String userName;
}
- @Document():給index命名,將實體類映射到數(shù)據(jù)庫，類似于@TableName
- @Id:將一個字段標記為主鍵
- @Field:配置一個字段的基本屬性，用analyzer屬性指定自定義分詞器
查詢es數(shù)據(jù)庫：
使用ElasticsearchRestTemplate對象的方法即可文章來源地址http://www.zghlxwxcb.cn/news/detail-777216.html
