Laravel 4 : Call to undefined method Redis::connection()

Question

I\'m going crazy about this error. I\'ve got a vagrant VM with Debian 7, generated with Puphpet, installation was fine.

1. Redis is installed and working

Answer 1

That error is because you have installed and enabled the module php5-redis, it became with the class Redis. To avoid that error and use the Laravel Redis Facade, you have to change the alias in app/config/app.php (or whatever is your environment).

'Redis' => 'Illuminate\Support\Facades\Redis'

'RedisFacade' => 'Illuminate\Support\Facades\Redis' //whatever you like

or just configure your cache.php to use Redis and use only the Cache class. :)

Answer 2

The problem isn't with your redis server setup -- there's something mis-configured or changed in your system.

The error you're seeing

Call to undefined method Redis::connection()

Is PHP telling you it can't find a method named connection on the class Redis. It's a PHP error, and PHP never gets around to trying to talk to the redis server.

Normally, in a Laravel 4.2 system, there is no class named Redis. Instead, an alias is setup in app/config/app.php

#File: app/config/app.php
'Redis'           => 'Illuminate\Support\Facades\Redis',

which turns Redis into a facade. This is what enables you to make calls like Redis::connection.

So, there's something wrong with your system. Either you

1. Have a custom class named Redis somewhere that's loaded before the aliases are setup

2. Have Redis aliased to something other than a the Illuminate\Support\Facades\Redis facade class

3. You Redis facade class has been modified to return a service identifier other than redis

4. You've rebound the redis service as some other class

5. Per the comments below, you have the Redis PHP extension installed and the global extension class "wins"

To find out where PHP thinks the Redis class is, try

$r = new ReflectionClass('Redis');
var_dump($r->getClassFile());

To see if #4 is the problem, try calling the service directly

$app = app();
$app['redis']->connection();

Good luck!

Answer 3

Install Redis extension on your PC.

Download the CORRECT version the DDL from the following link: https://pecl.php.net/package/redis/4.1.0/windows

Put the dll in the correct folder

Wamp -> C:\wamp\bin\php\php-XXXX\ext
Laragon -> C:\laragon\bin\php\php-XXX\ext

Edit the php.ini file adding

extension=php_redis.dll

Restart server and check phpinfo();. Now Redis should be there!

Answer 4

I came across this after encountering this issue and wanted to add another answer in case it helps someone else.

In my case there was an alias collision because my php configuration has the PHP-Redis module/extension enabled -- both the PHP module and Laravel seem to have a conflicting object named Redis. I was able to resolve this simply by using the entire namespaced identifier:

//$r = Redis::connection() 
$r = Illuminate\Support\Facades\Redis::connection();
