php 弹性搜索给出错误在您的集群中找不到任何活动节点

Elastic Search Give an error No alive nodes found in your cluster

提问by Tomas

I am start working with elastic search.I successfully install elastic search on my server(Different from application server).But When I try to call Elatic search from my Application server it gives an error Fatal error: Uncaught exception 'Elasticsearch\Common\Exceptions\NoNodesAvailableException' with message 'No alive nodes found in your cluster'

我开始使用弹性搜索。我在我的服务器上成功安装了弹性搜索（不同于应用程序服务器）。但是当我尝试从我的应用程序服务器调用 Elatic 搜索时，它给出了一个错误 Fatal error: Uncaught exception 'Elasticsearch\Common\Exceptions\NoNodesAvailableException' with message 'No alive nodes found in your cluster'

When I check Elastic search status it shows Active.

当我检查 Elastic 搜索状态时，它显示Active。

How can I call elastic search from my Application server to my Elastic search server.

如何从我的应用程序服务器调用弹性搜索到我的弹性搜索服务器。

<?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 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.

elasticsearch.yml settings which are not working

elasticsearch.yml 设置不起作用

network.host: 127.0.0.1

network.host: 127.0.0.1

network.host: 0

network.host: 0

network.host: 0.0.0.0

network.host: 0.0.0.0

network.host: IP_Address

network.host: IP_Address

network.bind_host: 0

network.bind_host: 0

network.bind_host: IP_Address

network.bind_host: IP_Address

When I set the above settings then elasticsearch shows the failed status.

当我设置上述设置时，elasticsearch 显示失败状态。

NOTE : Elastic search install on different server from my Application sever.

注意：弹性搜索安装在与我的应用程序服务器不同的服务器上。

I found the error.Error is coming due to space before node.nameand cluster.name.Remove the space and its working fine.

我发现 error.Error 由于node.name和cluster.name之前的空间而出现。删除空间及其工作正常。

Updated elasticsearch.yml file

I have found this error and solved it by following steps:

我发现了这个错误并通过以下步骤解决了它：

1. Comments the plugin setting on app/etc/env.php file.

   '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. Start the server.

3. upgrade magento

   php bin/magento setup:upgrade 
   

1. 注释 app/etc/env.php 文件中的插件设置。

   '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. 启动服务器。

3. 升级 magento

   php bin/magento setup:upgrade

I also facing the same problem. I was specified in host 'myhostaddress:9200'. Change it with IP of your Elasticsearch host server like '127.0.0.1:9200' . It resolve my problem.

我也面临同样的问题。我在主机“myhostaddress:9200”中被指定。使用您的 Elasticsearch 主机服务器的 IP 更改它，例如 '127.0.0.1:9200' 。它解决了我的问题。
