这是我的docker-compose.yml

Nginx:
    build: ./Nginx/
    ports:
        - 80:80
    links:
        - PHP
    volumes_from:
        - app

PHP:
    image: PHP:7.0-fpm
    expose:
        - 9000
    volumes_from:
        - app
    links:
        - elastic

app:
    image: PHP:7.0-fpm
    volumes:
        - .:/var/www/html
    command: "true"

elastic:
    image: elasticsearch:2.3
    volumes:
      - ./elasticsearch/data:/usr/share/elasticsearch/data
      - ./elasticsearch/logs:/usr/share/elasticsearch/logs
    expose:
      - "9200"
    ports:
      - "9200:9200"

当我尝试通过访问localhost：9200来访问Elasticsearch时,它可以工作.

但是当我尝试使用PHP创建索引时,我收到以下错误：

Fatal error: Uncaught
Elasticsearch\Common\Exceptions\NoNodesAvailableException: No alive
nodes found in your cluster in

这是客户端代码：

PHP

namespace App\Elasticsearch;

use Elasticsearch\ClientBuilder;

    class Client 
    {
        public static function getClient()
        {
            return ClientBuilder::create()
                ->build();
        }
    }

用于实例化Elasticsearch对象的代码：

PHP

require 'vendor/autoload.PHP';

use App\Elasticsearch\Client;
use App\Elasticsearch\Indices\UserIndex;

$es = Client::getClient();

如果我是var_dump($es),​​它会转储Elasticsearch客户端对象.

但是当我尝试创建索引时,它会抛出错误.

PHP

namespace App\Elasticsearch\Indices;

use App\Elasticsearch\Indices\AbstractIndex;
use Elasticsearch\Client; 

    class UserIndex extends AbstractIndex
    {
        public function __construct(Client $client)
        {
            $this->client = $client;
        }
    }

    // Create User Index
    $userIndex = new UserIndex($es);
    var_dump($userIndex->createIndex('users'));

更新

从enter link description here起

这一页.我试过了

$es = Client::getClient();

try {
    // Create User Index
    $userIndex = new UserIndex($es);
    var_dump($userIndex->createIndex('users'));
} catch (Exception $e) {
    var_dump($es->transport->getLastConnection()->getLastRequestInfo());
}

现在它显示了我的卷曲错误,即

[“curl”] array(2) { [“error”] “Failed to connect to localhost port
9200: Connection refused” [“errno”] 7
