Just installed ElasticSearch on my mac (brew install elasticsearch).
Then started it with: brew services start elasticsearch.
I can see it is running:
curl localhost:9200
{
"name" : "84ucGje",
"cluster_name" : "elasticsearch_dnk306",
"cluster_uuid" : "yU6wdZpJT_-1OvaFf7l7Ug",
"version" : {
"number" : "6.5.0",
"build_flavor" : "default",
"build_type" : "tar",
"build_hash" : "816e6f6",
"build_date" : "2018-11-09T18:58:36.352602Z",
"build_snapshot" : false,
"lucene_version" : "7.5.0",
"minimum_wire_compatibility_version" : "5.6.0",
"minimum_index_compatibility_version" : "5.0.0"
},
"tagline" : "You Know, for Search"
}
When I try to add some index to it - it fails with 406 error:
curl -XPOST localhost:9200/test/1 -d '{"title":"Hello world"}'
{"error":"Content-Type header [application/x-www-form-urlencoded] is not supported","status":406}
What do I need to do to make this work?
Thanks.

nothing, because this is the last issue i stucked on.
This JSON you provided means Elasticsearch is up and running perfectly fine. You can note in the JSON response, Elasticsearch cluster name, version, build type and other information is also provided.
{
"name": "ISBUS-PC02",
"cluster_name": "elasticsearch",
"cluster_uuid": "FE38HTACR2evmiVFD7ciag",
"version":
{
"number": "8.6.0",
"build_flavor": "default",

You don't have to worry, your Elasticsearch cluster is up and running and you can execute other requests.
I am using elastic search in my laravel project using package elasticquent, I followed this specific tutorial
Laravel Elastic Search
and before that I installed elastic search on my OS(Ubuntu) by following the documentation.
After setting all things I get no reply error after spending some time on error I ran to some solution which says I have to make changes in my elasticsearch.yml file
Changes I made
cluster.name = <my-cluster-name>
node.name = <my-node-name> //basically my System name
I got credentials for above field by the following command
curl --cacert /etc/elasticsearch/certs/http_ca.crt -u elastic http://localhost:9200
which gives response as follows
{
"name" : "Cp8oag6",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "AT69_T_DTp-1qgIJlatQqA",
"version" : {
"number" : "8.4.1",
"build_type" : "tar",
"build_hash" : "f27399d",
"build_flavor" : "default",
"build_date" : "2016-03-30T09:51:41.449Z",
"build_snapshot" : false,
"lucene_version" : "9.3.0",
"minimum_wire_compatibility_version" : "1.2.3",
"minimum_index_compatibility_version" : "1.2.3"
},
"tagline" : "You Know, for Search"
}
so after doing all setup and following the tutorial when I visit my search url I get
No nodes alive and If I try
curl -X GET localhost:9200 It gives no reply error.
{
"name" : "DESKTOP-BNTBBBG",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "DlRfjfPlRg69wUBRfy3kKQ",
"version" : {
"number" : "8.1.3",
"build_flavor" : "default",
"build_type" : "zip",
"build_hash" : "39afaa3c0fe7db4869a161985e240bd7182d7a07",
"build_date" : "2022-04-19T08:13:25.444693396Z",
"build_snapshot" : false,
"lucene_version" : "9.0.0",
"minimum_wire_compatibility_version" : "7.17.0",
"minimum_index_compatibility_version" : "7.0.0"
},
"tagline" : "You Know, for Search"
}
But When running this command
php bin/magento setup:install --base-url="http://versionup.magento.com" --db-host="localhost" --db-name="magento2" --db-user="magento2" --db-password="magento2" --admin-firstname="admin" --admin-lastname="admin" --admin-email="user#example.com" --admin-user="admin" --admin-password="Admin#123456" --language="en_US" --currency="USD" --timezone="America/Chicago" --use-rewrites="1" --backend-frontname="admin" --search-engine=elasticsearch7 --elasticsearch-host="localhost" --elasticsearch-port=9200
Could not validate a connection to Elasticsearch. Unknown 401 error from Elasticsearch null
i have the same problem, but now it's fixed.
make sure you enable xpack.security.http.ssl on elasticsearch.yml. because I disable it before.
then change the host to:
--elasticsearch-host="https://localhost"
then add more options to your command for authentication:
--elasticsearch-enable-auth=true --elasticsearch-username="elastic" --elasticsearch-password="your password"
I have an elasticsearch cluster which I can hit as follows:
▶ curl -k https://localhost:9200 -u username:password
{
"name" : "elasticsearch-sample-es-master-1",
"cluster_name" : "elasticsearch-sample",
"cluster_uuid" : "XXXXXXXXXXXXXXXXXXX",
"version" : {
"number" : "7.11.0",
"build_flavor" : "default",
"build_type" : "docker",
"build_hash" : "8ced7813d6f16d2ef30792e2fcde3e755795ee04",
"build_date" : "2021-02-08T22:44:01.320463Z",
"build_snapshot" : false,
"lucene_version" : "8.7.0",
"minimum_wire_compatibility_version" : "6.8.0",
"minimum_index_compatibility_version" : "6.0.0-beta1"
},
"tagline" : "You Know, for Search"
}
(I have port-forwarded the service locally)
However when hitting it with hey
hey https://localhost:9200 -a username:password
Status code distribution:
[401] 200 responses
Any ideas?
You can try the following
hey https://username:password#localhost:9200
That works!
Note: There are open issues in the official hey repository, https://github.com/rakyll/hey/issues/150
I changed JVM heap sized and Logstash cant connect to Elasticsearch, after restarting Elasticsearch
logstash.yml

xpack.monitoring.elasticsearch.password: pass
