I have a Laravel application that I am integrating a Redis Server into to handle the application caching. However I am having issues with the Redis configuration, as I am not able to access the Redis interface using the Laravel cache facade.
I set up a redis-server and comfirmed that it is working on the server:
> redis-cli
127.0.0.1:6379 > ping
PONG
I then followed the integration documentation for Redis/Laravel from here:
https://laravel.com/docs/5.7/redis
I installed the composer predis/predis package...
I set it up in Laravel to use the default redis config:
app/config/cache.php:
'default' => env('CACHE_DRIVER', 'redis'),
app/config/database.php:
'redis' => [
'client' => 'predis',
'default' => [
'host' => env('REDIS_HOST', '127.0.0.1'),
'password' => env('REDIS_PASSWORD', null),
'port' => env('REDIS_PORT', 6379),
'database' => env('REDIS_DB', 0),
],
'cache' => [
'host' => env('REDIS_HOST', '127.0.0.1'),
'password' => env('REDIS_PASSWORD', null),
'port' => env('REDIS_PORT', 6379),
'database' => env('REDIS_CACHE_DB', 1),
],
]
.env:
BROADCAST_DRIVER=log
CACHE_DRIVER=redis
QUEUE_CONNECTION=sync
SESSION_DRIVER=file
SESSION_LIFETIME=120
REDIS_HOST=127.0.0.1
REDIS_PASSWORD=null
REDIS_PORT=6379
Now when I test I can access Redis via the Redis Facade...
use Illuminate\Support\Facades\Redis;
...but not from the Cache Facade.
use Illuminate\Support\Facades\Cache;
// ************* this works
Redis::set('testFromRedisSet', 'RedisSet');
// ************* none of these work...
Cache::store('redis')->put('testFromStoreCachePut', 'CacheStorePut', 600);
Cache::put('testFromCachePut', 'CachePut', 600);
Cache::remember('testFromCacheRemember', 60, function() {
return "CacheRemember";
});
Cache::rememberForever('testFromCacheRememberForever', function() {
return "CacheRememberForever";
});
127.0.0.1:6379> KEYS '*'
1) "testFromRedisSet"
127.0.0.1:6379>
Interestingly enough the Cache Facade still appears to be functioning properly. If I monitor the cache requests in Telescope, the 4 cache requests in the example that are not showing up in the Redis Server are still being cached somewhere, and using the Cache facade to retrieve these 4 values works fine.
...all these retrieve the correct values:
Cache::get('testFromCacheStoreRedisPut');
Cache::get('testFromCachePut');
Cache::get('testFromCacheRemember');
Cache::get('testFromCacheRememberForever');
So what is going on here?
It looks like Laravel is utilizing the [redis] cache driver correctly, because when I shut down the Redis Server and retest the app the entire applications throws a Predis Connection Exception:
In AbstractConnection.php line 155: Connection refused [tcp://127.0.0.1:6379]
Where are the cache keys being stored and why can't I view the stored keys in the terminal using "redis-cli"?
redis-cli KEYS '*'
Monitoring the Redis Server shows me that Redis is storing the data and pushing event notifications, but all data that I can't see in the termimal is prefixed with laravel_cache. However there is no data or hash key with that name present in the interface.

1561596709.263678 [1 127.0.0.1:42064] "GET" "laravel_cache:telescope:pause-recording"
How can i accesss the data being stored in the laravel_cache namespace? Even running the same GET commands shown in the server monitor does not fetch any data directly.
Redis cache store uses the cache database connection by default. If you look at config/database.php it switches to database 1 for caching by default. To view the keys in the terminal, you have to select which database to use first.
127.0.0.1:6379> SELECT 1
127.0.0.1:6379[1]> KEYS *
Using different databases allows you to separate your cache and session store, it can be handy when you need to delete all cache keys (flushdb) but keep the user session. You can even add a separate connection for queues. Note that it's not recommended to use multiple databases, use multiple Redis instance instead.
As mentioned in the comments, Correctly setting the default would be a better solution than explicitly defining the store
You need to specify the store:
Cache::store('redis')->put('bar', 'baz', 600); // 10 Minutes
https://laravel.com/docs/5.8/cache#cache-usage
Simple Solution!
In config\database.php UPDATE the value of default & cache with 1
'redis' => [
'default' => [
// Other settings...
'database' => env('REDIS_DB', 1),
],
'cache' => [
// Other settings...
'database' => env('REDIS_CACHE_DB', 1),
],
],

Running Laravel 5.7 via Homestead.
This is happening in:
/vendor/laravel/framework/src/Illuminate/Redis/Connectors/PhpRedisConnector.php
"line":66
"function":"establishConnection"
We are using PHP Redis and in config/database.php:
'redis' => [
'client' => 'phpredis',
'default' => [
'host' => env('REDIS_HOST', '127.0.0.1'),
'password' => env('REDIS_PASSWORD', null),
'port' => env('REDIS_PORT', 6379),

I've seen other answers on here and none of the steps work. There is no redis cluster in use. PhpRedis extension is installed on VM and confirmed with php -m. Redis server is running at 127.0.0.1 and can be connected to outside of the code.
I'm unable to change the code as it works for others. It must be a configuration issue on my VM but I can't see what it could be. If anyone has had a similar issue I'd much appreciate any advice.
The problem you are having is because of class naming conflict: PhpRedisConnector creates new \Redis client, but it seems that you have alias for Illuminate\Support\Facades\Redis facade set up somewhere in your app. PhpRedisConnector creates new Redis and gets facade object instead.
Try removing this line in your config/app.php:
'aliases' => [
...
'Redis' => Illuminate\Support\Facades\Redis::class, // remove this line
...
]
I am using laravel 5.2 and having an architecture of multi-server autoscaling. I want to have session and cache in a centralized location. I want to use AWS elasticache for the same.
I have setup an elasticache Redis cluster having following options :
Parameter group : default.redis.3.2.cluster.on
Shards : 3
Total Nodes : 9
In laravel session configuration I have set redis as the session driver.
In database.php where redis configuration is set, i have used following :
REDIS_HOST=my_aws_elasticache_configuration_endpoint
REDIS_PASSWORD=null
REDIS_PORT=6379
.
When I try to use it, I get following error :
MOVED 13841 some_ip_address_of_aws:6379
I tried using local redis and it worked, so predis is working properly. I tried to check the solutions online, but not able to get the solution. I believe that the configuration endpoint is trying to redirect the redis connection to an available node url out of the 9 nodes I have. However, I have anticipated that AWS should do it internally and not throw exception. Can anyone help me?
I finally got an answer, we need to get the cluster mode on in database settings and set new cluster option to redis. This is how the redis config in database.php looks like :
'redis' => [
'client' => 'predis',
'options' => [
'cluster' => 'redis',
],
'clusters' => [
'default' => [
[
'host' => env('REDIS_HOST', 'localhost'),
'password' => env('REDIS_PASSWORD', null),
'port' => env('REDIS_PORT', 6379),
'database' => 0,
],
],
],
],
If you have password then you can replace options array with this :
'options' => [
'cluster' => 'redis',
'parameters' => ['password' => env('REDIS_PASSWORD', null)],
],
I am getting this error:
MongoDB\Driver\Exception\InvalidArgumentException: Failed to parse MongoDB URI: 'mongodb://mongo:tcp://172.17.0.3:27017/mydatabase' in /var/www/laravel/vendor/mongodb/mongodb/src/Client.php:81
My enviroment variables look like this:
MONGO_DATABASE="mydatabase"
MONGO_HOST="mongo"
MONGO_PASSWORD=""
MONGO_PORT="27017"
MONGO_USERNAME=""
and my database.php looks like this
'mongodb' => [
'driver' => 'mongodb',
'host' => env('MONGO_HOST', 'localhost'),
'port' => env('MONGO_PORT', 27017),
'database' => env('MONGO_DATABASE', 'mydatabase'),
'username' => env('MONGO_USERNAME', ''),
'password' => env('MONGO_PASSWORD', ''),
'options' => [
'database' => 'admin' // sets the authentication database required by mongo 3
]
I can correctly ping mongo from the container and it resolves to 172.17.0.3 as per the connection string. It seems as if the rest of the connection string is not getting generated correct?
I am running Laravel 5.2 and my package.json has this entry
"mongodb/mongodb": "^1.0.0",
"jenssegers/mongodb": "3.0.*",
As per https://github.com/jenssegers/laravel-mongodb 3.0.X is highest compatibility for Laravel 5.2.
Many thanks in advance
After further investigation my link from Amazon ECS was passing another MONGO_PORT which was overriding the env set in my .env file.
I have installed Laravel 5.1 with Redis and when I have tested it, I got error Database [redis] not configured..
Than I have tested it from routes using Redis instead of Eloquent model:
Route::get('/', function () {
Redis::set("key", "testValue");
return Redis::get("key");
});
And success...
After this i have searched and founded just it -
Laravel Redis configuration
there is no support for Redis there
What to do If i want to use Redis ?
There is redis support for Laravel
First you should install redis server and start it as service.
config/database.php
'redis' => [
'cluster' => false,
'default' => [
'host' => '127.0.0.1',
'port' => 6379,
'database' => 0,
],
],
Usage example:
\Cache::store('redis')->get('key', 'value', 10);
\Cache::store('redis')->get('key');
Official Documentation: https://laravel.com/docs/5.1/redis
I am currently creating an app with Laravel and Redis. Almost everything is working fine. I extended the Authentication as explained in the documentation, users can subscribe, login, logout ... I can create content and everything is stored in Redis.
But I have one issue. I can't run commands like "php artisan route:list", I have an error message : "[InvalidArgumentException] Database [redis] not configured.".
Th question is, is there anything special to do to make Artisan commands work when you set Redis as you database ? (basic configurations explained in the documention have been done and almost everything else is working fine).
Config:
In config/database.php I have:
return [
...
'default' => 'redis',
...
'redis' => [
'cluster' => false,
//'connection' => 'default',
'default' => [
'host' => '127.0.0.1',
'port' => 6379,
'database' => 7,
],
],
...
PS : You have the same error when you try to access the /password/email (password reset url).
InvalidArgumentException in DatabaseManager.php line 246:
Database [redis] not configured.
As Robert says in the comments, it looks like there is this error because there is no support for Redis as database for laravel.
