Laravel5使用ElasticSearch

https://blog.csdn.net/qq_16829085/article/details/80725125

1. 安装elasticsearch和ik插件 （elasticsearch的使用需要配置java环境，自行百度配置好java环境） elasticsearch集成包（包括ik中文插件）安装地址：https://github.com/medcl/elasticsearch-rtf       
2. 测试安装  启动elasticSearch：bin/elasticSearch -d       windows系统以管理员身份运行elasticsearch.bat
3. 测试是否安装成功  127.0.0.1:9200 
4. 安装 ElasticSearch Scout Engine 包

   composer require tamayo/laravel-scout-elastic

     安装这个包的时候，顺便就会装好 Laravel Scout，发布一下资源

   php artisan vendor:publish --provider="Laravel\Scout\ScoutServiceProvider"

   5.在app.php中添加对应的Provider

               Laravel\Scout\ScoutServiceProvider::class,
               ScoutEngines\Elasticsearch\ElasticsearchProvider::class,

   6.在count.php中配置参数

    'driver' => env('SCOUT_DRIVER', 'elasticsearch'),
    
    'elasticsearch' => [
           'index' => env('ELASTICSEARCH_INDEX', 'laravel5'),
           'hosts' => [
               env('ELASTICSEARCH_HOST', 'http://127.0.0.1:9200'),
           ],
       ],

   7.创建ylaravel的索引和模板

   • php artisan make:command ESInit  创建命令行
   • 修改ESInit.php文件

     <?php
      
     namespace App\Console\Commands;
      
     use GuzzleHttp\Client;
     use Illuminate\Console\Command;
      
     class ESInit extends Command
     {
         /**
          * The name and signature of the console command.
          *
          * @var string
          */
         protected $signature = 'es:init';
      
         /**
          * The console command description.
          *
          * @var string
          */
         protected $description = 'init laravel es for post';
      
         /**
          * Create a new command instance.
          *
          * @return void
          */
         public function __construct()
         {
             parent::__construct();
         }
      
         /**
          * Execute the console command.
          *
          * @return mixed
          */
         public function handle()
         {
      
             $client = new Client();
             // 创建模版
             $url = config('scout.elasticsearch.hosts')[0] . '/_template/tmp';
             $client->put($url, [
                 'json' => [
                     'template' => config('scout.elasticsearch.index'),
                     'settings' => [
                         'number_of_shards' => 1
                     ],
                     'mappings' => [
                         '_default_' => [
                             '_all' => [
                                 'enabled' => true
                             ],
                             'dynamic_templates' => [
                                 [
                                     'strings' => [
                                         'match_mapping_type' => 'string',
                                         'mapping' => [
                                             'type' => 'text',
                                             'analyzer' => 'ik_smart',
                                             'ignore_above' => 256,
                                             'fields' => [
                                                 'keyword' => [
                                                     'type' => 'keyword'
                                                 ]
                                             ]
                                         ]
                                     ]
                                 ]
                             ]
                         ]
                     ]
                 ]
             ]);
      
             $this->info("========创建模板成功=======");
      
             $url = config('scout.elasticsearch.hosts')[0] . '/' . config('scout.elasticsearch.index');
             $client->put($url, [
                 'json' => [
                     'settings' => [
                         'refresh_interval' => '5s',
                         'number_of_shards' => 1,
                         'number_of_replicas' => 0,
                     ],
                     'mappings' => [
                         '_default_' => [
                             '_all' => [
                                 'enabled' => false
                             ]
                         ]
                     ]
                 ]
             ]);
             $this->info("========创建索引成功=======");
     }
      
     }

     挂载ESInit，在APP\Console\Kerbel.php文件$commands数组中添加如下代码

     \App\Console\Commands\ESInit::class

     8.调用es脚本    php artisan es:init

     9.导入数据库和数据

     修改数据模型，以post为例

     <?php
      
     namespace App;
     use Illuminate\Database\Eloquent\Model;
     use Illuminate\Database\Eloquent\Builder;
     use Laravel\Scout\Searchable; class Post extends Model
     {
         use Searchable;
      
         protected $guarded=[]; //不可以注入的字段
      
         //定义索引里面的type
         public function searchableAs()
         {
             return 'posts_index';
         }
      
         //定义有哪些字段需要搜索
         public function toSearchableArray()
         {
             return[
                 'title'=>$this->title,
                 'content'=>$this->content,
             ];
         } 

     • 导入数据模型，php artisan scout:import “App\Post”
     • 验证 http://localhost:9200/laravel5/posts_index/1

     10.Postcontroller中完成功能代码的撰写

         public function search()
         {
             $this->validate(request(),[
                 'query'=>'required'
                 ]);
             $query=request('query');
      
      
             $posts=Post::search($query)->paginate(10);
             return view('post/search',compact('posts','query'));
         }
