when i am running elastic search on windows 10 , i can not open elastic portal in the local host and i got this message :
{
"name" : "ISBUS-PC02",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "FE38HTACR2evmiVFD7ciag",

},

}
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",

You don't have to worry, your Elasticsearch cluster is up and running and you can execute other requests.

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"
after install elasticsearch 7.12.1
with this config
network.host: 127.0.0.1
http.port: 9200
discovery.seed_hosts: ["127.0.0.1", "[::1]"]
in main page of elasticsearch show json
{
"name" : "master",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "_na_",
"version" : {
"number" : "7.12.1",
"build_flavor" : "default",
"build_type" : "zip",
"build_hash" : "3186837139b9c6b6d23c3200870651f10d3343b7",
"build_date" : "2021-04-20T20:56:39.040728659Z",
"build_snapshot" : false,
"lucene_version" : "8.8.0",
"minimum_wire_compatibility_version" : "6.8.0",
"minimum_index_compatibility_version" : "6.0.0-beta1"
},
"tagline" : "You Know, for Search"
}
and in xpack license is null
you should add
node.name: master
cluster.initial_master_nodes: ["master"]
to your elasticsearch.yml file and restart elasticsearch service
I am having sping boot application and if i use my local elastic search i am able to connect but if i used the remote elastic search i'am not able to connect.
spring:
data:
elasticsearch:
cluster-name: es_psc
cluster-nodes: 100.84.57.2:9300
if i run in browser(http://100.84.57.2:9200/) I am able to see the details
{
"name" : "i58Q9JC",
"cluster_name" : "es_psc",
"cluster_uuid" : "EKeTJwviQvWeTzbS1h1w4w",
"version" : {
"number" : "6.4.3",
"build_flavor" : "default",
"build_type" : "tar",
"build_hash" : "fe40335",
"build_date" : "2018-10-30T23:17:19.084789Z",
"build_snapshot" : false,
"lucene_version" : "7.4.0",
"minimum_wire_compatibility_version" : "5.6.0",
"minimum_index_compatibility_version" : "5.0.0"
},
"tagline" : "You Know, for Search"
}
But I i run my spring boot application its giving below error:
Caused by: org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes are available: [{#transport#-1}{6SiLGoTHTmmiuzBTvweb3A}{100.84.57.2}{100.84.57.2:9300}]
You are using the wrong port in your config file. You should be using port 9200, which is meant for rest communication.
Port 9300 is used for internal communication between Elasticsearch nodes.
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.
