Detailed explanation of operating es commands on Elasticsearch linux
1. Check whether the ES node starts normally
curl http://127.0.0.1:9200
非正常状态：
1>确保服务是不是正常启动了，端口用的是哪个
2>防火墙是否关闭或者端口是否开放
3>你的curl命令是否有问题，curl命令可能导致服务无法访问，可以尝试重启服务后，在外部浏览器访问URL地址即可。不一定非得用curl
2. Query all indexes in es, all existing indexes
curl http://127.0.0.1:9200/_cat/indices?v
3. Delete the index
curl -XDELETE http://127.0.0.1:9200/oam_behavior?pretty
4. Create es index
curl -XPUT http://127.0.0.1:9200/oam_behavior?pretty
5. Query all data of es
curl -XGET http://127.0.0.1:9200/oam_behavior/_search?pretty -k
6. Query the specified ID data
curl -XGET http://127.0.0.1:9200/oam_behavior/oam_log/00-ab7259b3-6860-48cb-b6b1-c8ab77bbb45c?pretty -k
7. Delete the specified ID data
curl -XDELETE http://127.0.0.1:9200/oam_behavior/oam_log/00-ab7259b3-6860-48cb-b6b1-c8ab77bbb45c?pretty -k
8. Query paging data (from refers to the record from which size refers to the number of displayed items)
curl -XPOST http://127.0.0.1:9200/oam_behavior/_search?pretty -H 'content-Type:application/json' -d '{"query":{"match_all":{}},"from":10,"size":10}'
9. Add a piece of data
curl -XPUT http://127.0.0.1:9200/oam_behavior/user/2?pretty -H 'content-Type:application/json' -d '{"name":"xxx","age":"23"}'
10. Query by ID
curl http://127.0.0.1:9200/oam_behavior/user/2?pretty
