Laravel4 Predis access to Redis returns error while reading line from the server

I used the Laravel 4 framework development and wanted to switch the cache server from Memcache to Redis, and the driver in config/cache.php was set to Redis. But call Cache::get () error, error information such as:

[2014-10-21 18:47:44] production.ERROR: exception 'Predis\Connection\ConnectionException' with message 'Error while reading line from the server [tcp://127.0.0.1:6379]' in /home/nginx/mono/vendor/predis/predis/lib/Predis/Connection/AbstractConnection.php:141

However, accessing Redis-server from Redis-cli is OK, and it is no problem to test Redis separately in PHPUnit. But the direct use of the route is problematic.

Route::get('/test', function(){
    Cache::put('name', 'Taylor', 60); //error！

    $name = Cache::get('name'); 

    echo $name;
});

Who can explain the problem?

Add: Refresh multiple/test, there will be a few normal.

Predis's Streamconnection Class

Production. ERROR

Is there a folder in configproduction? Is there a cache.php file inside? That would overwrite the outside configuration.
