Elastic search Give an error No live nodes found in your cluster

Question

I am starting to work with elastic search. I successfully install elastic search on my server (as opposed to the application server). But when I try to call Elatic search from my application server, it gives Fatal error: Uncaught exception 'Elasticsearch\Common\Exceptions\NoNodesAvailableException' with message 'No alive nodes found in your cluster'

When I check the Elastic search status, it shows Active .

What can I call elastic search from my application server on my Elastic search server.

 <?php require 'vendor/autoload.php'; $hosts = [ 'ip_address:9200' // IP + Port ]; $client = Elasticsearch\ClientBuilder::create()->setHosts($hosts)->build(); $params = [ 'index' => 'my_index', 'type' => 'my_type', 'id' => 'my_id', 'body' => ['testField' => 'abc'] ]; $response = $client->index($params); ?>

elasticsearch.yml settings that do not work

network.host: 127.0.0.1

network.host: 0

network.host: 0.0.0.0

network.host: IP_Address

network.bind_host: 0

network.bind_host: IP_Address

When I set the above settings, elasticsearch shows a failed status.

NOTE. Sustainable search is installed on another server from my application.

Answer 1

I found that the error. The erosion is due to the space up to node.name and cluster.name . Remove the space and its work.

PHP code

  <?php require 'vendor/autoload.php'; $indexParams = [ 'index' => 'my_index', 'body' => [ 'settings' => [ 'number_of_shards' => 5, 'number_of_replicas' => 1 ] ] ]; $client = Elasticsearch\ClientBuilder::create() ->setSSLVerification(false) ->setHosts(["IP_ADDRESS:9200"])->build(); $response = ''; try { /* Create the index */ $response = $client->indices()->create($indexParams); print_r($response); print_r($response); } catch(Exception $e) { echo "Exception : ".$e->getMessage(); } die('End : Elastic Search'); ?>
