Can't connect to redis

[starit]

Hi, this is my first time to use lumen, and version is 5.2 I want to connect to redis, and I have already installed these softwares in my Macbook

• Apache/2.4.18 (Unix)
• PHP 7.0.6
• PHP70-redis extension

Then I got this problem.

FatalThrowableError in Database.php line 25: Type error: Argument 1 passed to Illuminate\Redis\Database::__construct() must be of the type array, null given, called in ./vendor/illuminate/redis/RedisServiceProvider.php on line 24

I've also installed predis by using composer, but it didn't work.

Also, I found that it seems like to be an invalid path in file ./vendor/illuminate/cache/RedisStore.php use Illuminate\Redis\Database as Redis; the Redis directory do not exists....

What should I do ?

[GrahamCampbell]

Make sure $app->register(Illuminate\Redis\RedisServiceProvider::class); is in bootstrap/app.php.

[GrahamCampbell]

For example:

[starit]

I do have $app->register(Illuminate\Redis\RedisServiceProvider::class); in my bootstrap/app.php. when I open this issue I spent haft day in solving this problem and finally success.

I need to add these config code in the bootstrap/app.php: config(['database.redis'=> [ 'cluster' => env('REDIS_CLUSTER', false), 'default' => [ 'host' => env('REDIS_HOST', '127.0.0.1'), 'port' => env('REDIS_PORT', 6379), 'database' => env('REDIS_DATABASE', 0), 'password' => env('REDIS_PASSWORD', null), ], ]]); and it works now

[GrahamCampbell]

Looks like you didn't set up the redis.php config correctly.

[starit]

@GrahamCampbell I wonder where the redis.php config in Lumen is? There is no configs folder in Lumen.

[Garbee]

@starit You have to create the folder in the app and copy any configs you need to modify from the framework package into it.

[starit]

thanks. @Garbee

[ooing]

@starit can you tell me how to do ? thank very much

[amlun]

@ooing copy files from vendor/laravel/lumen-framework/config/database.php and redis.php to your app/config, then replace the config value. Also, config this code in bootstrap/app.php $app->configure('database'); $app->configure('cache');

[ooing]

@amlun thanks

[viirre]

I wanted to use Redis for queues and needed to add $app->configure('database'); in bootstrap/app.php to make it work (after added everything that the docs says).

The reason for this is that in RedisServiceProvider.php, Lumen resolves the config for the database to pass to the RedisManager class. If Lumen is not configured to work with a database, then the config will be NULL and it won't work.

[ingria]

https://github.com/laravel/lumen-framework/issues/414#issuecomment-219657373 <--- This should be added to the docs. There are no info about adding the redis section to DB config.

[ptasker]

Yup @viirre is right, $app->configure('database'); is missing in the docs.
