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/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'));

    }
