laravel8 elasticsearch 配置搭建使用

laravel 8框架  扩展elasticsearch 

首先 elasticsearch 的版本号 需要和 扩展的版本号对应

composer require elasticsearch/elasticsearch

然后是配置到common 调用文件

<?php
namespace App\Es;

use Elasticsearch\ClientBuilder;

class MyEs
{
    //ES客户端链接
    private $client;

    /**
     * 构造函数
     * MyElasticsearch constructor.
     */
    public function __construct()
    {

        　　// 带有账号、密码的客服端信息
        　　$hosts = [
            　　[
                　　'host' => '127.0.0.1',      // 域名
                　　'port' => '9200',           // 端口
                　　'scheme' => 'http',         // 协议
                　　'user' => 'elastic',        // 账号
                　　'pass' => '123456'        　// 密码
            　　]
