エラスティック検索エラーを発生させるクラスターにアライブノードが見つかりません

エラスティック検索の使用を開始しました。サーバーにエラスティック検索を正常にインストールしました（アプリケーションサーバーとは異なります）。しかし、アプリケーションサーバーからElatic検索を呼び出そうとすると、エラーFatal error: Uncaught exception 'Elasticsearch\Common\Exceptions\NoNodesAvailableException' with message 'No alive nodes found in your cluster'

Elastic検索のステータスを確認すると、Activeと表示されます。

アプリケーションサーバーからElastic SearchサーバーにElastic Searchを呼び出すにはどうすればよいですか。

<?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);
?>

My elasticsearch.yml Settings

    # ======================== Elasticsearch Configuration =========================
    #
    # NOTE: Elasticsearch comes with reasonable defaults for most settings.
    #       Before you set out to Tweak and tune the configuration, make sure you
    #       understand what are you trying to accomplish and the consequences.
    #
    # The primary way of configuring a node is via this file. This template lists
    # the most important settings you may want to configure for a production cluster.
    #
    # Please see the documentation for further information on configuration options:
    # <http://www.elastic.co/guide/en/elasticsearch/reference/current/setup-configuration.html>
    #
    # ---------------------------------- Cluster -----------------------------------
    #
    # Use a descriptive name for your cluster:
    #
     cluster.name: my-application
    #
    # ------------------------------------ Node ------------------------------------
    #
    # Use a descriptive name for the node:
    #
     node.name: node-1
    #
    # Add custom attributes to the node:
    #
    # node.rack: r1
    #
    # ----------------------------------- Paths ------------------------------------
    #
    # Path to directory where to store the data (separate multiple locations by comma):
    #
    # path.data: /path/to/data
    #
    # Path to log files:
    #
    # path.logs: /path/to/logs
    #
    # ----------------------------------- Memory -----------------------------------
    #
    # Lock the memory on startup:
    #
    # bootstrap.memory_lock: true
    #
    # Make sure that the `ES_HEAP_SIZE` environment variable is set to about half the memory
    # available on the system and that the owner of the process is allowed to use this limit.
    #
    # Elasticsearch performs poorly when the system is swapping the memory.
    #
    # ---------------------------------- Network -----------------------------------
    #
    # Set the bind address to a specific IP (IPv4 or IPv6):
    #
    #network.Host: 0.0.0.0
    #network.bind_Host: 0
    #
    # Set a custom port for HTTP:
    #

    #
    # For more information, see the documentation at:
    # <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html>
    #
    # --------------------------------- Discovery ----------------------------------
    #
    # Pass an initial list of hosts to perform discovery when new node is started:
    # The default list of hosts is ["127.0.0.1", "[::1]"]
    #
    # discovery.zen.ping.unicast.hosts: ["Host1", "Host2"]
    #
    # Prevent the "split brain" by configuring the majority of nodes (total number of nodes / 2 + 1):
    #
    # discovery.zen.minimum_master_nodes: 3
    #
    # For more information, see the documentation at:
    # <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-discovery.html>
    #
    # ---------------------------------- Gateway -----------------------------------
    #
    # Block initial recovery after a full cluster restart until N nodes are started:
    #
    # gateway.recover_after_nodes: 3
    #
    # For more information, see the documentation at:
    # <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-gateway.html>
    #
    # ---------------------------------- Various -----------------------------------
    #
    # Disable starting multiple nodes on a single system:

    #
    # Require explicit names when deleting indices:

動作していないelasticsearch.yml設定

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

上記の設定を行うと、elasticsearchは失敗ステータスを表示します。

注：アプリケーションサーバーとは別のサーバーにElastic Searchをインストールします。

エラーが見つかりました。node.nameおよびcluster.nameの前にスペースが原因でエラーが発生しています。スペースとその動作を削除します。

このエラーを見つけて、次の手順で解決しました。

  1. App/etc/env.phpファイルのプラグイン設定にコメントします。

    'system' => [
'default' => [
  /* 'smile_elasticsuite_core_base_settings' => [
 'es_client' => [
  'servers' => 'node-1:9200,node-2:9200',
  'enable_https_mode' => '0',
  'enable_http_auth' => '0',
  'http_auth_user' => '',
  'http_auth_pwd' => ''
   ]
  ] */
 ]
]

  2. サーバーを起動します。

  3. magentoのアップグレード

    php bin/magento setup:upgrade

私も同じ問題に直面しています。ホスト「myhostaddress：9200」で指定されました。 Elasticsearch HostサーバーのIPを '127.0.0.1:9200'のように変更します。それは私の問題を解決します。

あなたの答えは私が提供しているリンクで見つけることができます https://forums.aws.Amazon.com/thread.jspa?threadID=230626 同じ問題ですが、このリンクを介して解決し、末尾にサフィックス：443を付けることを提案する答えが機能します
