ElasticSearch笔记

官网的docker真是...简配了很多东西.连个vi也没有

https://hub.docker.com/_/elasticsearch

docker network create somenetwork

docker run -d --name elasticsearch --net somenetwork -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch
docker run -d --name kibana --net somenetwork -p 5601:5601 kibana

简单地就可以用了

更详细的在这里, compose

https://www.elastic.co/guide/en/elasticsearch/reference/7.5/docker.html

顺便, compose的安装

yum install docker-compose
docker-compose --version

官方非常好的文档,研读一下
https://docs.docker.com/compose/gettingstarted/

先不使用java来操作es, 试试python

基本操作, 关于索引的

查看所有索引: GET _cat/indices
健康状况:    GET _cat/health?v
查看索引:    GET /{indexName}?pretty
查看节点:    GET /_cat/nodes?v
