Today, I will talk to you about the commonly used curl commands in ElasticSearch, which may not be well understood by many people. in order to make you understand better, the editor has summarized the following for you. I hope you can get something according to this article.

1. Curl-XGET 'http://10.240.0.8:9200/_cat' options supported by the cluster

Cymbal

two。 View node information curl-XGET 'http://10.240.0.8:9200/_cat/nodes?v'

Cymbal

3. View master node information curl-XGET 'http://10.240.0.8:9200/_cat/master?v'

Cymbal

4. Check the health status of the cluster curl-XGET 'http://10.240.0.8:9200/_cat/health?v'

Cymbal

You can see that our cluster is called "es-test" and the status is green.

Whenever we ask for the health status of the cluster, we get three: green, yellow, and red.

Green means that all functions are intact.

Yellow means that all data is available, but some copies have not yet been allocated

Red represents some data that is no longer available for some reason. Note that although a cluster is in red state, it can still provide some services (for example, it will continue to search through available slice data), but after you lose some of the data, you need to fix it as fast as you can.

5. Create an index # test_one index name # pretty parameter indicates a well-formatted JSON response (if present) curl-XPUT 'http://10.240.0.7:9200/test_one?pretty'

Cymbal

6. View the index list curl-XGET 'http://10.240.0.7:9200/_cat/indices?v'

Cymbal

Test_one is the index you just created

7. Delete index

Delete based on index name

Curl-XDELETE 'http://10.240.0.8:9200/test_3?pretty'

Cymbal

8. Create a document

When inserting a document (dic) into an es, you must specify a type (type)

1. To create a document using PUT, you need to specify the id# index index:test_one# type type:test_type# _ id:1curl-XPUT "http://10.240.0.7:9200/test_one/test_type/1"-d'{" name ":" john "," age ": 28}'

Cymbal

If the error is reported above, you need to access the request header.

Curl-H "Content-Type: application/json"-XPUT "http://10.240.0.7:9200/test_one/test_type/1?pretty"-d'{" name ":" eson "," age ": 35}'

Cymbal

two。 To create a document using POST, you can not specify id (randomly generate id when not specified) curl-H "Content-Type: application/json"-XPOST 'http://10.240.0.7:9200/test_one/test_type?pretty'-d' {"name": "suzhang"}'

Cymbal

9. View the document curl-XGET 'http://10.240.0.7:9200/test_one/test_type/1?pretty'

Cymbal

10. Replace document

When you use PUT and specify id, es replaces the original document with a new document

Curl-H "Content-Type: application/json"-XPUT 'http://10.240.0.7:9200/test_one/test_type/1?pretty'-d' {"name": "su"}'

Cymbal

11. Update the document curl-H "Content-Type: application/json"-XPOST 'http://10.240.0.7:9200/test_one/test_type/2/_update?pretty'-d' {"doc": {"name": "suxxxnxxg"}'

Cymbal

twelve。 Delete document curl-XDELETE 'http://10.240.0.7:9200/test_one/test_type/2?pretty'
