Elastic Search 报错 No alive nodes found in your cluster答案

【问题标题】：Elastic Search Give an error No alive nodes found in your clusterElastic Search 报错 No alive nodes found in your cluster
【发布时间】：2017-07-21 20:01:36
【问题描述】：

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（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弹性搜索时，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'

当我检查 Elastic 搜索状态时，它显示 Active。

如何将弹性搜索从我的应用程序服务器调用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:
    #
    # http.port: 9200
    #
    # 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:
    #
    # 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：弹性搜索安装在与我的应用程序服务器不同的服务器上。

【问题讨论】：

您是否在配置文件中添加了network.bind_host: 0 以启用来自本地主机以外的侦听功能？
尝试在elasticsearch.yml中添加network.bind_host: IP_of_your_elastic_search_server，重启弹性搜索服务并尝试从你的应用服务器ip:9200
@Kamran Sir 当我设置 network.bind_host: 0 或 network.bind_host: IP_of_your_elastic_search_server 然后检查 elasticsearch 状态它的显示失败。当我评论“#network.bind_host:0”然后它的显示活动。
停止elasticsearch服务，添加network.host: 0.0.0.0再次启动服务。
别忘了把你的 elsaticsearch 服务器 ip 放在 $hosts = ['ip_address:9200']; 数组中

【解决方案1】：

我发现了错误。由于 node.name 和 cluster.name 之前的空间而出现错误。删除空间并正常工作。

更新了 elasticsearch.yml 文件

【讨论】：

但是“elasticsearch.yml”文件在哪里，我很难找到这个文件，但我没有得到任何类型的文件，所以请知道它在哪里...谢谢
@Yagneshbhalala 最有可能在 /etc/elasticsearch/elasticsearch.yml 如果没有，请尝试在命令行输入updatedb，然后输入locate elasticsearch|grep elasticsearch.yml

【解决方案2】：

我发现了这个错误并通过以下步骤解决了它：

评论 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' => ''
   ]
  ] */
 ]
]

启动服务器。
升级magento
```
php bin/magento setup:upgrade 
```

【解决方案3】：

我也面临同样的问题。我在主机'myhostaddress:9200'中被指定。使用 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。

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，但是通过这个链接解决了，建议在末尾附加后缀 :443 的答案将起作用

【解决方案5】：

删除弹性搜索中的尾部斜杠。有时它会产生错误。

至少在我的情况下，我从 Amazon ES URL 中删除了尾部斜杠使其正常工作。

【解决方案6】：

我在 magento2 中也面临同样的问题

然后，我安装了

$sudo apt-get install elasticsearch
