部署服务

docker run启动elastic服务

docker pull elasticsearch:6.7.2

docker run -d -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:6.7.2

docker-compose.yml的方式部署

version: '2.2'
services:
  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:6.7.2
    container_name: elasticsearch
    environment:
      - cluster.name=docker-cluster
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - esdata1:/usr/share/elasticsearch/data
    ports:
      - 9200:9200
    networks:
      - esnet
  elasticsearch2:
    image: docker.elastic.co/elasticsearch/elasticsearch:6.7.2
    container_name: elasticsearch2
    environment:
      - cluster.name=docker-cluster
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
      - "discovery.zen.ping.unicast.hosts=elasticsearch"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - esdata2:/usr/share/elasticsearch/data
    networks:
      - esnet

volumes:
  esdata1:
    driver: local
  esdata2:
    driver: local

networks:
  esnet:

elastic常用命令

查看集群是否健康

　　curl 'localhost:9200/_cat/health?v'

获取集群的节点列表

　　curl 'localhost:9200/_cat/nodes?v'

列出所有索引

curl 'localhost:9200/_cat/indices?v'

建立名为customer的索引

　curl -XPUT 'localhost:9200/customer?pretty'

向索引customer,类型为external,添加数据

　　curl -XPUT 'localhost:9200/customer/external/1?pretty' -d '
　　{
       　　  "name": "John Doe"
　　}'

获取数据

获取customer索引下类型为external，id为1的数据，pretty参数表示返回结果格式美观。

   curl -XGET 'localhost:9200/customer/external/1?pretty'

删除索引 DELETE

curl -XDELETE 'localhost:9200/customer?pretty'

修改数据,如果不存在，就新增

curl -XPUT 'localhost:9200/customer/external/1?pretty' -d '
　　{

 　　 "name": "John Doe"

　　}'

更新数据

　　curl -XPOST 'localhost:9200/customer/external/1/_update?pretty' -d '
　　{

 　　 "doc": { "name": "Jane Doe", "age": 20 }
　　}'

删除一条记录数据

curl -XDELETE 'localhost:9200/customer/external/2?pretty'
