windows环境下，进入安装目录。点击elasticsearch.bat即可。
如果是linux环境,内存要大一点.

1.下载:wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.5.1.zip
2.解压:unzip elasticsearch-5.5.1.zip
3.进入目录:cd elasticsearch-5.5.1/
4.前台启动: ./bin/elasticsearch
5.后台启动: ./bin/elasticsearch -d
6.检查启动: curl localhost:9200

如图既安装成功
laravel 融合 elasticsearch 在个人博客中使用

注意：elasticsearch 依赖jdk环境，具体环境自己网上安装查看，这里不详述

安装scout

composer require laravel/scout

安装elasticsearch

composer require tamayo/laravel-scout-elastic

安装guzzlehttp包：

composer require guzzlehttp/guzzle

在config/app.php的providers 数组添加：

laravel\scout\scoutserviceprovider::class,
scoutengines\elasticsearch\elasticsearchprovider::class,

发布配置文件：

php artisan vendor:publish --provider="laravel\scout\scoutserviceprovider"

发布生成的config/scout.php文件添加

 'driver' => env('scout_driver', 'elasticsearch'),
    'elasticsearch' => [
        'index' => env('elasticsearch_index', 'laravel'),//索引名称
        'hosts' => [
            env('elasticsearch_host', 'http://127.0.0.1:9200'),
        ],
    ],

php artisan make:command esinit

具体实现代码如下：

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';
    /**
     * create a new command instance.
     *
     * @return void
     */
    public function __construct()
    {
        parent::__construct();
    }
    /**
     * execute the console command.
     *
     * @return mixed
     */
    public function handle()
    {
        $client = new client();
        $this->createtemplate($client);
        $this->createindex($client);
    }
//创建索引
    protected function createindex($client)
    {
        $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
                        ]
                    ]
                ]
            ]
        ]);
    }
//创建模板
    protected function createtemplate($client)
    {
        $url = config('scout.elasticsearch.hosts')[0] .'/_template/rtf';
        $client->put($url, [
            'json' => [
                'template' => '*',
                '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'
                                            ]
                                        ]
                                    ]
                                ]
                            ]
                        ]
                    ]
                ]
            ]
        ]);
    }
}

初始化脚本

php artisan es:init

namespace app\models;
use laravel\scout\searchable;
class article extends basemodel
{
    use searchable;
    protected $guarded = [];
    protected $table = 'article';
    public function tosearchablearray()
    {
        return [
            'title' => $this->title,
            'content' => $this->content
        ];
    }
}

namespace app\http\controllers\web;
use app\http\controllers\controller;
use app\models\article;
use illuminate\http\request;
class indexcontroller extends controller
{
    public function search(request $request)
    {
        $params=$request->keyword;
        $article= article::search($params)->paginate();
        return $this->output($article, '请求成功', status_ok);
    }
}

php artisan scout:import "app\models\article"

命令完成会有如下提示，同时es里面也会将数据库指定字段写入
