Iam using Tymon/JWT for authentication in my lumen project.All is working fine when Redis isn't configured. when Redis is configured for cache, am getting error for middleware routes(Redis hasn't been used in any of the files yet) like
Authorization Token not found.
Package used
composer require predis/predis
composer require illuminate/redis
Here is my code
config/database.php
'redis' => [
'cluster' => false,
'default' => [
'host' => '127.0.0.1',
'port' => 6379,
'database' => 0,
],
],
In bootstrap/app.php
//Redis
$app->register(Illuminate\Redis\RedisServiceProvider::class);
$app->alias('redis', Illuminate\Support\Facades\Redis::class);

Until now I was using Predis for my cache in the Laravel project. Now I want to switch to PhpRedis. I've read it's really simple (just config changes), but I have a lot of problems. I don't know what to begin with, so I'll write all what I know.
My hosting provider claims that PhpRedis is enabled.
The code below executed in a controller (Predis is set) works fine - I receive the set value.
$redis = new \Redis();
$redis->connect( 'socket path', 0 );
$redis->set('test', 'testValue');
print_r( $redis->get('test') );
However, the same code in the raw PHP file executed via SSH returns "Uncaught Error: Class 'Redis' not found in..."
Let's go to changes in config/database.php. Here is my configuration:
'redis' => [
'client' => env('REDIS_CLIENT', 'predis'/*'phpredis'*/),
'cluster' => true,
'options' => [
'cluster' => env('REDIS_CLUSTER', 'predis'/*'redis'*/),
'prefix' => Str::slug(env('APP_NAME'), '_').'_',
'parameters' => ['password' => env('REDIS_PASSWORD', null)],
],
'default' => [
'scheme' => 'unix',
'path' => env('REDIS_HOST'),
'host' => env('REDIS_HOST'),
'password' => env('REDIS_PASSWORD'),
'port' => env('REDIS_PORT'),
'database' => env('REDIS_CACHE_DB', 0)
],
(...) // other
],
When I change values to these in comments, my website shows just a blank page - any errors in the mailbox.
Furthermore, when I run for example "php73 artisan config:clear" in the SSH, console returns "Please remove or rename the Redis facade alias in your "app" configuration file in order to avoid collision with the PHP Redis extension." in the Illuminate/Redis/Connectors/PhpRedisConnector.php.
When I change the alias in config/app.php from "Redis" to "RedisManager" and try again it returns
Uncaught Error: Class 'Redis' not found in /path/vendor/laravel/framework/src/Illuminate/Redis/Connectors/PhpRedisConnector.php:70.
What's going on? How to set Laravel's configuration to use PhpRedis? Maybe it's my hosting provider issue? Thanks in advance for every advice.
If I missed some important code, give me a sign - I will add it.
The PHPRedis libraries are not installed by default in a shared hosting environment, and are generally not part of a PHP installation by default. You would have to ask your host to install these libraries within their shared hosting platform.
I've been migrating databases from mLab to MongoDB Atlas (mLab is being terminated Nov 10th). I've been trying to put make a mongo url dsn connection to connect to my Atlas cluster. However, when I put in the connection, I get this error:

I have been told this is how you connect to MongoDB Atlas from this source stackoverflow post

I'm having a problem connecting to ElastiCache Redis from Laravel application installed on EC2 instance or even using redis-cli from EC2 instance.
Laravel
I tried to use predis with configurations in database.php like
'redis' => [
'client' => 'predis',
'default' => [
'host' => env('REDIS_HOST', '127.0.0.1'),
'password' => env('REDIS_PASSWORD', null),
'port' => env('REDIS_PORT', 6379),
'database' => 0,
'read_write_timeout' => -1,
'timeout' => 0
],
],
and got 'Error while reading line from the server. [tcp:server here]'
I tried with phpRedis extension with same configurations only change 'client' => 'phpredis' and got error read error on connection {"exception":"[object] (RedisException(code: 0): read error on connection at vendor/laravel/framework/src/Illuminate/Redis/Connectors/PhpRedisConnector.php:69)
Redis cli
Using redis cli redis-cli -h host_here -p 6379 -a password_here I see prompt like host:6379> but typing any command throws error Error: Connection reset by peer
ElastiCache Redis configurations
My EC2 and elastic cache are in the same VPC and using telnet I can connect to redis instance
~$ telnet host 6379
Trying 172.31.23.113...
Connected to host.
Escape character is '^]'.
Thanks for any help!
I know this is pretty old but I was having the same issue myself. If anyone encounters this issue then see the solution here and here.
It seems that when you enable Encryption in-transit in AWS Elasticache it prevents you from using redis-cli as it doesn't support TLS connections. Switching to another client should work. This answer has a list of TLS enabled clients.
Edit:
Did some more digging and found that using stunnel you can wrap your connection of redis-cli with ssl. Here is a guide for doing it.
Related: Laravel + Redis Cache via SSL?
To which I've answered here: https://stackoverflow.com/a/48876398/663058
Relevant details below:
Since you have clustering and TLS then you'll need a different config entirely:
'redis' => [
'client' => 'predis',
'cluster' => env('REDIS_CLUSTER', false),
// Note! for single redis nodes, the default is defined here.
// keeping it here for clusters will actually prevent the cluster config
// from being used, it'll assume single node only.
//'default' => [
// ...
//],
// #pro-tip, you can use the Cluster config even for single instances!
'clusters' => [
'default' => [
[
'scheme' => env('REDIS_SCHEME', 'tcp'),
'host' => env('REDIS_HOST', 'localhost'),
'password' => env('REDIS_PASSWORD', null),
'port' => env('REDIS_PORT', 6379),
'database' => env('REDIS_DATABASE', 0),
],
],
'options' => [ // Clustering specific options
'cluster' => 'redis', // This tells Redis Client lib to follow redirects (from cluster)
]
],
'options' => [
'parameters' => [ // Parameters provide defaults for the Connection Factory
'password' => env('REDIS_PASSWORD', null), // Redirects need PW for the other nodes
'scheme' => env('REDIS_SCHEME', 'tcp'), // Redirects also must match scheme
],
'ssl' => ['verify_peer' => false], // Since we dont have TLS cert to verify
]
]
Explaining the above:
'client' => 'predis': This specifies the PHP Library Redis driver to use (predis).
'cluster' => 'redis': This tells Predis to assume server-side clustering. Which just means "follow redirects" (e.g. -MOVED responses). When running with a cluster, a node will respond with a -MOVED to the node that you must ask for a specific key.
If you don't have this enabled with Redis Clusters, Laravel will throw a -MOVED exception 1/n times, n being the number of nodes in Redis cluster (it'll get lucky and ask the right node every once in awhile)
'clusters' => [...]: Specifies a list of nodes, but setting just a 'default' and pointing it to the AWS 'Configuration endpoint' will let it find any/all other nodes dynamically (recommended for Elasticache, because you don't know when nodes are comin' or goin').
'options': For Laravel, can be specified at the top-level, cluster-level, and node option. (they get combined in Illuminate before being passed off to Predis)
'parameters': These 'override' the default connection settings/assumptions that Predis uses for new connections. Since we set them explicitly for the 'default' connection, these aren't used. But for a cluster setup, they are critical. A 'master' node may send back a redirect (-MOVED) and unless the parameters are set for password and scheme it'll assume defaults, and that new connection to the new node will fail.
If you are using predis as client.
Then you can change Redis connection in config/database.php
'redis' => [
'client' => 'predis',
'default' => [
'scheme' => 'tls',
'host' => env('REDIS_HOST', '127.0.0.1'),
'password' => env('REDIS_PASSWORD', null),
'port' => env('REDIS_PORT', 6379),
'database' => 0,
],
],
You can add 'scheme' in that.
I am using Laravel 5.8 And then everything works great within Laravel.
But yes, as Redis doesn't provide TLS connection so redis-cli will still not work.
I've tried to set up memcached with my Laravel
Set Driver
/config/app.php
'default' => 'memcached',
Configure Memcache Server
'stores' => [
'database' => [
'driver' => 'database',
'table' => 'caches',
'connection' => null,
],
'memcached' => [
'driver' => 'memcached',
'servers' => [
[
'host' => '127.0.0.1', 'port' => 11211, 'weight' => 100,
],
],
]
],
Cache
Route::get('cache/users', function() {
return Cache::remember('users', 60, function() {
return User::all();
});
});
How do I know I configure my caching with memcache properly ?
How do I see what I stored ?
First, you can use Cache::has('users') and Cache::get('users') in php artisan tinker or on a test route of some sort to see if stuff's being saved to the cache (and what the current contents are).
Second, you can connect to memcached (as well as other drivers like redis) via telnet and check directly.
telnet 127.0.0.1 11211
Once in, you can issue commands, like:
get users
which should spit out the contents of that cache key.
With the code you've shown, a non-working cache should also result in an exception. You can test this by turning off the memcached instance and refreshing the page - it should error out.
For the case when Memcache is on separate machine named memcached, i.e. docker with corresponding service: in .env set MEMCACHED_HOST=memcached
