All you need is to set the same keyPrefix for both applications

'cache' => [
    'class'     => 'yii\caching\FileCache',
    'keyPrefix' => 'common'
],

Tested with Yii2 basic template.

I was getting same issue which was resolved by keeping same setting for backend and frontend both apps.

'cache'=> array(
    'class' => 'CRedisCache',
    'hostname' => 'localhost',
    'port' => 6379,
    'database' => 0,
    'hashKey' => false,
    'keyPrefix' => '',
);

set keyPrefix to empty and hashKey to false,

if you use default setting for keyPrefix and hashKey CRedisCache will create different keys for same value provided from set command eg.

 Yii::app()->cache->set('foo', 'bar'); frontend server 
will create key in redis something like "0327f5f7378e9056c775ab69aa206322"

  Yii::app()->cache->set('foo', 'bar'); backend server 
ll create key in redis something like "d2c81df2db2285435c1975b5cb5c5b66"

CRedisCache creates unique key by using combination of hashKey and keyPrefix for every requested server.

Frontend configuration file:

'cache' => array(
    'class'     => 'system.caching.' . (!MW_DEBUG ? 'CFileCache' : 'CDummyCache'),
    'keyPrefix' => md5('frontend.' . MW_VERSION . Yii::getPathOfAlias('frontend')),
),

Console configuration file:

'cache' => array(
  'class'     => 'system.caching.' . (!MW_DEBUG ? 'CFileCache' : 'CDummyCache'),
  'keyPrefix' => md5('console.' . MW_VERSION . Yii::getPathOfAlias('backend')),
),
