在yii2应用程序中使用mysql和redis

我正在构建一个CRM系统,该系统应该允许不同用户进行不同的访问,因此我需要在面板中进行复杂的身份验证和通知。但主系统应该使用REDIS。我已经安装了yii2 redis插件,并在db.php(mysql config)中有这样的配置:

<?php
return [
    'class' => 'yii\db\Connection',
    'dsn' => 'mysql:host=localhost;dbname=yii2basic',
    'username' => 'root',
    'password' => '',
    'charset' => 'utf8',
    // Schema cache options (for production environment)
    //'enableSchemaCache' => true,
    //'schemaCacheDuration' => 60,
    //'schemaCache' => 'cache',
];

在web.php中:

$db = require __DIR__ . '/db.php';
$config = [
    'id' => 'basic',
    'basePath' => dirname(__DIR__),
    'bootstrap' => ['log'],
    'aliases' => [
        '@bower' => '@vendor/bower-asset',
        '@npm'   => '@vendor/npm-asset',
    ],

'components' => [
        'redis'         => [

            'class'    => 'yii\redis\Connection',

            'hostname' => 'localhost',

            'port'     => 6379,

            'database' => 0,

        ],
     ],
     'db' => $db,

我如何区分我的模型,使用mysql或redis?我假设如果我在组件部分指定redis,整个应用程序使用redis db。我可以使用具有多个值的redis作为密钥,但由于redis在达到最大内存时丢弃了密钥,所有注册用户及其配置文件都会显示出来,所以我认为我应该使用mysql这个basci的东西(带有角色的数据库,验证,个人资料)

return [
   'components' => [
      'db1' => [
        'class' => 'yii\db\Connection',
        'dsn' => 'mysql:host=localhost;dbname=db1name', //maybe other dbms such as psql,...
        'username' => 'db1username',
        'password' => 'db1password',
    ],
    'db2' => [
        'class' => 'yii\redis\Connection',
        'dsn' => 'YOURCONFIG', 
        'port' => '6379',
        'password' => 'db2password',
        'username' => 'db2username',
    ],
  ],
];

然后尝试使用

// To get from db1
Yii::$app->db1->createCommand((new \yii\db\Query)->select('*')->from('tbl_name'))->queryAll()

// To get from db2
Yii::$app->db2->createCommand((new \yii\db\Query)->select('*')->from('tbl_name'))->queryAll();

对于模型中的活动记录,写入

// db1
public function getDb() {
    return Yii::$app->db1;
}

//Or db2
public function getDb() {
    return Yii::$app->db2;
}
