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