windows7+laravel8+Elasticsearch7.9.3环境搭建步骤及使用

管理员 发布于 8个月前   276

因为要用Elasticsearch测试一下数据,所以在windows7电脑上搭建一回,顺便记录一下增加一篇博文

开始准备必要条件:

1.elasticsearch-7.9.3-windows-x86_64.zip,我在官网下载最新的,几k每秒捶胸口,最后在是在群里问群友要的;

2.laravel8,已经装好,phpStudy环境已跑起,用的是博客laravel8仿栏目的环境,有兴趣的看一下我之前的博文有记录


一.把Elasticsearch跑起来,解压直接运行文件:D:\elasticsearch-7.9.3\bin\elasticsearch.bat

cmd.exe

...

启动完:

二.安装elasticsearch扩展,我这直接安装最新的,注意composer的时候记得转阿里云镜像源,不然要卡死

composer require elasticsearch/elasticsearch

三.laravel8中配置文件 .env、config/database.php 

1. .env 在底部添加

ES_HOSTS=127.0.0.1:9200

2. config/database.php 也在底部添加

'elasticsearch' => [
    // Elasticsearch 支持多台服务器负载均衡,因此这里是一个数组
    'hosts' => explode(',', env('ES_HOSTS')),
]

四.将elasticsearch对象注入到laravel容器中 在laravel项目文件

App\Provider\AppServiceProvider.php
<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\Schema; //add fixed sql
use Elasticsearch\ClientBuilder as ESClientBuilder;
class AppServiceProvider extends ServiceProvider
{
    /**
     * Register any application services.
     * @return void
     */
    public function register()
    {
        // 注册一个名为 es 的单例
        $this->app->singleton('es', function () {
            // 从配置文件读取 Elasticsearch 服务器列表
            $builder = ESClientBuilder::create()->setHosts(config('database.elasticsearch.hosts'));
            // 如果是开发环境
            if (app()->environment() === 'local') {
                // 配置日志,Elasticsearch 的请求和返回数据将打印到日志文件中,方便我们调试
                $builder->setLogger(app('log')->driver());
            }
            return $builder->build();
        });
    }
    /**
     * Bootstrap any application services.
     * @return void
     */
    public function boot()
    {
        //
        Schema::defaultStringLength(191); //add fixed sql
    }
}

五.laravel项目中使用elasticsearch

1.routes\api.php文件中添加  (路由功能描述在控制器里面)

//测试路由 Elasticsearch
use App\Http\Controllers\API\TestController;
Route::get('test', [TestController::class, 'test']);
Route::get('testinsert', [TestController::class, 'testinsert']);
Route::get('testmysqllist', [TestController::class, 'testmysqllist']);

2.添加测试控制器文件 app\Http\Constrollers\API\TestController.php

<?php
namespace App\Http\Controllers\API;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use App\Models\User;
use Elasticsearch\ClientBuilder;
class TestController extends Controller
{
    public $client = null;
    public function __construct() {
        $this-> client = ClientBuilder::create()->build();
    }
    
    //根据索引名(表名),跟id取出数据
    public function test()
    {
        $a = app('es')->get(['index' => 'name', 'id' => 2]);
        dd($a);
    }
    //从数据库表中取出数据 对应库表 存入Elasticsearch中(当然我这是测试就没有对应库表)
    public function testinsert()
    {
        $id = 2;
        $info = User::where(['id' => 2])->first()->toArray();
        $params = [
            'index' => 'name',
            'type' => 'title',
            'id' => $id,
            'body' => ['testField' => $info]
        ];
        $response = $this->client->index($params);
        dd($response);
    }
    //打印Elasticsearch中所有索引数据
    public function testmysqllist()
    {
        $client = ClientBuilder::create()->build();
        $data = [
            'type' => 'title'
        ];
        $response = $client->search($data);
        dd($response['hits']['hits']);
        return $response['hits']['hits'];
    }
}

3.看看 testmysqllist方法的 效果

array:4 [▼
  0 => array:5 [▼
    "_index" => "name"
    "_type" => "title"
    "_id" => "3"
    "_score" => 1.0
    "_source" => array:1 [▼
      "testField" => array:10 [▼
        "id" => 3
        "name" => "站长二号"
        "email" => "5142245@qq.com"
        "email_verified_at" => null
        "current_team_id" => null
        "profile_photo_path" => null
        "created_at" => "2020-09-30T06:00:25.000000Z"
        "updated_at" => "2020-09-30T06:00:25.000000Z"
        "subscribe" => 0
        "profile_photo_url" => "https://ui-avatars.com/api/?name=%E7%AB%99%E9%95%BF%E4%BA%8C%E5%8F%B7&color=7F9CF5&background=EBF4FF"
      ]
    ]
  ]
  1 => array:5 [▼
    "_index" => "name"
    "_type" => "title"
    "_id" => "2"
    "_score" => 1.0
    "_source" => array:1 [▼
      "testField" => array:10 [▼
        "id" => 2
        "name" => "站长小号"
        "email" => "houtizong@dingtalk.com"
        "email_verified_at" => null
        "current_team_id" => null
        "profile_photo_path" => null
        "created_at" => "2020-09-30T06:00:25.000000Z"
        "updated_at" => "2020-09-30T06:00:25.000000Z"
        "subscribe" => 1
        "profile_photo_url" => "https://ui-avatars.com/api/?name=%E7%AB%99%E9%95%BF%E5%B0%8F%E5%8F%B7&color=7F9CF5&background=EBF4FF"
      ]
    ]
  ]
  2 => array:5 [▼
    "_index" => "name1"
    "_type" => "title"
    "_id" => "1"
    "_score" => 1.0
    "_source" => array:1 [▶]
  ]
]

六.cmd.exe中测试
