在yii2下使用其需要的插件，特别简单方便，如果你没有安装composer，请先安装

1.安装mongodb支持

 composer require –prefer-dist yiisoft/yii2-mongodb

使用时，在components中添加配置

‘mongodb’ => [

     ‘class’ => ‘yii\mongodb\Connection’,

     # 有账户的配置

      //’dsn’ => ‘mongodb://demofancyecommerce:fdaVBDFS#fdfdtyg423DF23#$@localhost:27017/demofancyecommerce’,

      # 无账户的配置

      ‘dsn’ => ‘mongodb://127.0.0.1:27017/market’,

],

检查php支持mongodb扩展，php -im | grep mongodb，没有的话需要先安装mongodb扩展

2. 安装smarty

composer require yiisoft/yii2-smarty

在组件配置里申明渲染view，或者自定义smarty工具，直接在controller自定义使用。

‘components’ => [

‘view’ => [

‘renderers’ => [

‘tpl’ => [

‘class’ => ‘yii\smarty\ViewRenderer’,

//’cachePath’ => ‘@runtime/Smarty/cache’,

],

],

],

],

3. 安装redis支持

php composer.phar require --prefer-dist yiisoft/yii2-redis

‘redis’ =>[

‘class’ => ‘yii\redis\Connection’,

‘hostname’ => ‘localhost’,  //你的redis地址

‘port’ => 6379, //端口

‘database’ => 0,

]

4. 安装 elasticsearch

php composer.phar require elasticsearch/elasticsearch
