Elasticsearch之curl创建索引库

Elasticsearch之curl创建索引

　　

注意事项

1、索引库名称必须要全部小写，不能以下划线开头，也不能包含逗号

2、如果没有明确指定索引数据的ID，那么es会自动生成一个随机的ID,需要使用POST参数

　　curl -XPOST http://192.168.80.200:9200/zhouls/emp/ -d '{"name" : "tom"}'

3、如果想要确定我们创建的都是全新的数据

　　1：使用随机ID(post方式)

　　2：在url后面添加参数

　　curl -XPUT http://192.168.80.200:9200/zhouls/emp/2/_create -d '{"name":"tom","age":25}'

[hadoop@djt002 elasticsearch-2.4.3]$ curl -XPUT 'http://192.168.80.200:9200/zhouls/emp/1' -d'{"name":"tom","age":25}'
{"_index":"zhouls","_type":"emp","_id":"1","_version":1,"_shards":{"total":2,"successful":1,"failed":0},"created":true}[hadoop@djt002 elasticsearch-2.4.3]$ ^C

[hadoop@djt002 elasticsearch-2.4.3]$ curl -XPOST 'http://192.168.80.200:9200/zhouls/emp' -d'{"name":"tom","age":25}'
{"_index":"zhouls","_type":"emp","_id":"AVpdAus-cJQ8qYq5I_Er","_version":1,"_shards":{"total":2,"successful":1,"failed":0},"created":true}[hadoop@djt002 elasticsearch-2.4.3]$

[hadoop@djt002 elasticsearch-2.4.3]$
[hadoop@djt002 elasticsearch-2.4.3]$

　　得出，

不指定id，就必须得用-XPOST

3、

[hadoop@djt002 elasticsearch-2.4.3]$ curl -XPUT 'http://192.168.80.200:9200/zhouls/emp/1' -d'{"name":"tom","age":25}'

[hadoop@djt002 elasticsearch-2.4.3]$

　　这样做的好处，是，只要这条命令成功，那么就一定是新增的。
