elasticSearch简单入门

安装

# 新建docker-elasticsearch目录
$ mkdir docker-elasticsearch
# 进入docker-elasticsearch目录
$ docker-elasticsearch
# 新建config文件夹并修改权限
$ mkdir config && chmod 777 -R config
# 新建data文件夹
$ mkdir data && chmod 777 -R data
# 写入配置到config目录下的elasticsearch.yml中
$ echo "http.host: 0.0.0.0" >> config/elasticsearch.yml

编写docker-compose.yml文件

version: '3'
services:
  elasticsearch:
    image: elasticsearch:7.10.1
    container_name: elasticsearch
    restart: always
    ports:
      - 9200:9200
      - 9300:9300
    environment:
      - "ES_JAVA_OPTS=-Xms64m -Xmx128m"
      - discovery.type=single-node
    volumes:
      - ./config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml
      - ./data:/usr/share/elasticsearch/data
      - ./data/plugins:/usr/share/elasticsearch/data/plugins

安装好了以后在浏览器输入HOST:9200, 显示以下界面, 说明安装成功了

安装kibana

version: '2'
services:
  kibana:
    container_name: kibana
    image: kibana:7.10.1
    ports:
      - "5601:5601"
    restart: always
    environment:
      - ELASTICSEARCH_HOSTS=http://192.168.4.5:9200

elasticsearch基本操作

插入数据(PUT, POST)

PUT /account/_doc/1
{
  "name": "Felix",
  "age": 18,
  "company": [
    {
      "name": "BFKJ",
      "address": "LIUZHOU"
    },
    {
      "name": "aliyun",
      "address": "hangzhou"
    }
  ]
}

// 该方法不需要指定id, 会默认生成一个随机id
POST user/_doc
{
  "name": "Felix",
  "company": "bfkj"
}

// 没有数据就插入, 有数据就报错
POST user/_create/1
{
  "name": "Felix",
  "company": "bfkj"
}
