Elasticsearchs的安装/laravel-scout和laravel-scout-elastic的安装

安装:

https://github.com/medcl/elasticsearch-rtf

先下载包

下载解压后

cd elasticsearch-rtf-master

ll

bin/elasticsearch-plugin list 这里会显示所有的插件

过滤插件

bin/elasticsearch-plugin list > /tmp/plugin.log

vim /tmp/plugin.log 在这里面把我们需要的analysis-ik这个插件去掉

cat /tmp/plugin.log|xargs -I {} bin/elasticsearch-plugin remove {}  //删除

bin/elasticsearch-plugin list //查看

bin/elasticsearch -d  //启动

ps aux|grep java

查看是否启动::   vim logs/elasticsearch.log

127.0.0.1:9200

安装laravel使用elastic的包

安装laravel/scout   查看文档地址 https://laravel-china.org/docs/laravel/5.4/scout/1276

接下来安装laravel-scout-elastic

执行这个

composer require tamayo/laravel-scout-elastic

报这个错,我查了下,最终找到原因,是我安装的

laravel/scout版本太高了,我给降到5.0就ok啦

后面的按照这个网址走就行啦    https://github.com/ErickTamayo/laravel-scout-elastic

来到项目中的config\scout.php中修改配置

 'elasticsearch' => [
        'index' => env('ELASTICSEARCH_INDEX', 'laravel'),
        'hosts' => [
            env('ELASTICSEARCH_HOST', 'http://localhost'),
        ],
    ]

就ok啦,主要查看文档,!!!!

使用laravel的command实现搜索引擎索引和模板的建立

分为三步走:

创建Command

php artsan make:command ESInit

然后来到下面这个类

然后查看php  artisan 就会看到 ps:init命令

编辑handle

在ESInit.php文件中,添加文件

 use GuzzleHttp\Client; 

需要安装这个插件

composer require GuzzleHttp/guzzle

public function handle()
    {
        //创建template
        $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=====");

    }

挂载到laravel的artisan中去

然后这边,我们来到控制台

php artisan es:init 就ok了
