<?php

    use Elasticsearch\ClientBuilder;

    require 'vendor/autoload.php';

    $client = ClientBuilder::create()->build();
$params = [
    'index' => 'my_index',
    'type' => 'my_type',
    'id' => 'my_id',
    'body' => ['testField' => 'abc']

执行 php 1.php 

结果

解决： 需要指定节点的ip和端口号

<?php

    use Elasticsearch\ClientBuilder;

    require 'vendor/autoload.php';

$host=['192.168.1.142:9200'];
$client = ClientBuilder::create()->setHosts($host)->build();

$params = [
    'index' => 'my_liming',
    'type' => 'my_type',
    'id' => 'my_id',
    'body' => ['testField' => '123213213c']
];

$response = $client->index($params);
print_r($response);

成功：
