彈性搜索提供錯誤在羣集中找不到活動節點

Question

我開始使用彈性搜索。我在我的服務器上成功安裝了彈性搜索（與應用程序服務器不同）。但是當我嘗試從我的應用程序服務器調用Elatic搜索時它給出了一個錯誤 Fatal error: Uncaught exception 'Elasticsearch\Common\Exceptions\NoNodesAvailableException' with message 'No alive nodes found in your cluster'

當我檢查彈性搜索狀態它顯示活動。

如何從我的應用程序服務器向彈性搜索服務器調用彈性搜索。

<?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); 
?> 

我elasticsearch.yml設置

# ======================== Elasticsearch Configuration =========================

    # The primary way of configuring a node is via this file. This template lists

    # 
    # Use a descriptive name for the node:

elasticsearch.yml設置未工作

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

當我設置了上述設置，然後elasticsearch顯示失敗的狀態。

注意：彈性搜索安裝在與我的應用服務器不同的服務器上。

我發現error.Error之前node.name和cluster.name卸下襬臂的空間和它的做工精細即將到期的空間。

更新elasticsearch.yml文件

PHP代碼

<?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'); 

?> 

成功響應：
