Try this:

Edit config.php in frontend or backend

'language' => 'ru',
'i18n' => [
        'translations' => [
            'app*' => [
                'class' => 'yii\i18n\PhpMessageSource',
                'basePath' => '@app/messages',
                'fileMap' => [
                    'app' => 'app.php',
                ],
            ],
        ],
    ],

create app.php in frontend/messages/ru/app.php or backend/messages/ru/app.php

View:

echo \Yii::t('app', 'I am a message!');
