Laravel5使用ElasticSearch

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

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
测试安装  启动elasticSearch：bin/elasticSearch -d       windows系统以管理员身份运行elasticsearch.bat
测试是否安装成功  127.0.0.1:9200
 
   
    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/110.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'));
    }
