elasticsearchHow can users get started with Elasticsearch?
- First, users need to download and install Elasticsearch on their system.
- Once installed, users can start an instance of Elasticsearch by running the following command in the terminal:
$ bin/elasticsearch
- After starting the instance, users can verify that it is running by making a HTTP request to the cluster using curl:
$ curl -X GET "localhost:9200"
## Output example
{
"name" : "Gwendolyn",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "mXo_b7-VQm-2E9TKXe9h3g",
"version" : {
"number" : "7.3.0",
"build_flavor" : "default",
"build_type" : "tar",
"build_hash" : "ef48eb35cf30adf4db14086e8aabd07ef6fb113f",
"build_date" : "2019-07-24T19:35:50.547737Z",
"build_snapshot" : false,
"lucene_version" : "8.1.0",
"minimum_wire_compatibility_version" : "6.8.0",
"minimum_index_compatibility_version" : "6.0.0-beta1"
},
"tagline" : "You Know, for Search"
}
- The output shows that the instance is running and provides information about the version of Elasticsearch.
- After verifying the instance is running, users can begin to index data into Elasticsearch. To do this, users need to send a
POST
request with the data they want to index as the body of the request. For example:
$ curl -X POST "localhost:9200/customer/external" -H 'Content-Type: application/json' -d'
{
"name": "John Doe"
}
'
## Output example
{
"_index" : "customer",
"_type" : "external",
"_id" : "1",
"_version" : 1,
"result" : "created",
"_shards" : {
"total" : 2,
"successful" : 1,
"failed" : 0
},
"_seq_no" : 0,
"_primary_term" : 1
}
- The output shows that the document was created successfully.
