弹性搜索出错在群集中找不到活动节点

标签： php search elasticsearch server

我开始使用弹性搜索。我在我的服务器上成功安装弹性搜索（与应用程序服务器不同）。但是当我尝试从我的应用程序服务器调用Elatic搜索时出现错误 Fatal error: Uncaught exception 'Elasticsearch\Common\Exceptions\NoNodesAvailableException' with message 'No alive nodes found in your cluster'

当我检查弹性搜索状态时，它会显示有效。

如何从我的应用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);
?>

我的elasticsearch.yml设置 

    # ======================== 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:

    # 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:
    #
    # node.max_local_storage_nodes: 1
    #
    # Require explicit names when deleting indices:
    #
    # action.destructive_requires_name: true

elasticsearch.yml设置不起作用

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

当我设置上述设置时，elasticsearch会显示失败状态。

注意：弹性搜索安装在我的应用程序服务器的不同服务器上。

我发现error.Error是由于 node.name 和 cluster.name 之前的空格而来的。删除空格及其工作正常。

更新了elasticsearch.yml文件

我发现了此错误，并通过以下步骤解决了该问题：

  1. 评论app / etc / env.php文件上的插件设置。

    '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

我也面临着同样的问题。我在主机“ myhostaddress：9200”中指定。使用您的Elasticsearch主机服务器的IP（例如'127.0.0.1:9200'）进行更改。它解决了我的问题。

您的答案可以在我提供的链接中找到https://forums.aws.amazon.com/thread.jspa?threadID=230626 我遇到了同样的问题，但是通过这个链接它解决了，建议附加后缀的答案：443在最后会起作用

答案 4 :(得分：0)

我在magento2中也面临同样的问题

然后，我安装了

$sudo apt-get install elasticsearch
