How to enable rbac caching?

Question

Yii

I tried to use this example https://habrahabr.ru/post/251847/ rbac caching
But I got it after this common/config/main.php code

'components' => [
        'cache' => [
            'class' => 'yii\caching\FileCache',
        ],
        'cacheRbac' => [
            'class' => 'yii\caching\ApcCache',
        ]
    ],

common/config/main-local.php

return => [
'components' => [
'authManager' => [
            'class' => 'yii\rbac\DbManager',
            'cache' => 'cacheRbac',
        ],
}
]

And writes the problem ApcCache requires PHP apc extension to be loaded.
As I understand it, this extension is not there and the second moment is how to download it.
I have already visited the site www.php.net/apc, I need to install something as I understand it, and the second point is how to transfer it to the hosting?
And my php version is 5.6

2. It is not necessary to use apc for rbac, it will work with other types of cache. Choose:
