I’m being told by the docs that Redis is supported in 2.8.x and that all I need is a locally running instance of a Redis server using the default port, and I just have to select the Redis driver from the admin->general page as the caching driver choice.
And yet I’m consistently being told that EE cannot connect to Redis.

Redis is running and I can interact with it from the command line, but EE seems incapable.

Has anybody out there successfully used Redis for native caching (not ce_cache, which cannot cope with layouts) and if so, can you please tell me what magic you used to make it happen?

Many thanks in advance,

Andy

Hey Andy,

You’re not alone.
I’ve tried almost every configuration possible to get EE 2.9.2 to work with my Redis server without any luck. It just doesn’t seem to work at all.
I tried adding config overrides:

$config['redis'] = array(
  'host' => 'localhost',
  'password' => NULL,
  'port' => 6379,
  'timeout' => 0
);

or

$config['redis'] = array(
  'host' => '127.0.0.1',
  'password' => NULL,
  'port' => 6379,
  'timeout' => 0
);

I know my redis server work as I have other sites (Magento) on that same server that use Redis without any problems at all. EE just keeps on returning the error “Cannot connect to Redis, using File driver instead”.
Even if you go to Tools -> Utilities -> PHP Info it shows that Redis is enabled:

Redis Support enabled
Redis Version 2.2.5

I wonder if guys at EllisLab got this cache driver to work in their test lab.

Cheers,
Jacek

Just found a solution to this:

Put this in your config.php:

$config['cache_driver'] = 'redis';
