I want to use both memcached and apc at the same time for caching, how can I configure and use it in laravel.
By using the Cache facade you can specify what cache type you want to use.
Cache::store('memcached')->put('bar', 'baz', 10); // Using memcached
Cache::store('apc')->put('bar', 'baz', 10); // Using apc
As you can see in your app/config/cache.php there is already some preconfigured cache types set up:
'stores' => [
'apc' => [
'driver' => 'apc',
],
'array' => [
'driver' => 'array',
],
'database' => [
'driver' => 'database',
'table' => 'cache',
'connection' => null,
],
'file' => [
'driver' => 'file',
'path' => storage_path('framework/cache'),
],
'memcached' => [
'driver' => 'memcached',
'servers' => [
[
'host' => env('MEMCACHED_HOST', '127.0.0.1'),
'port' => env('MEMCACHED_PORT', 11211),
'weight' => 100,
],
],
],
'redis' => [
'driver' => 'redis',
'connection' => 'default',
],
],
You now need to make sure, memcached and APC are correctly installed on your system.
Using the Memcached cache requires the Memcached PECL package to be installed.
Using APC cache requires the APC package on your system

I have configured Redis (using a socket) in the Laravel in my hosting server. Everything works fine (I have tested reading from cache, sessions etc.), I have one database for a cache and a second one for users sessions.
However, when I run "php artisan cache:clear" it shows the error:
"In AbstractConnection.php line 155: Connection refused [unix:/path/.redis/redis.sock]".
This error also occures when I run any command which uses Redis, for example "php73 artisan cron:updateForeignPrices".
.env
CACHE_DRIVER=redis
SESSION_DRIVER=redis
REDIS_HOST=/path/.redis/redis.sock
REDIS_PASSWORD=null
REDIS_PORT=0
REDIS_CACHE_DB=0
REDIS_SESSION_DB=1
config/database.php
'redis' => [
'client' => env('REDIS_CLIENT', 'predis'),
'cluster' => true,
'options' => [
'cluster' => env('REDIS_CLUSTER', 'predis'),
'prefix' => Str::slug(env('APP_NAME'), '_').'_',
'parameters' => ['password' => env('REDIS_PASSWORD', null)],
],

Hosting provider's info about Redis (translated):
Socket: /path-to-my-directory/.redis/redis.sock
User and password: (none)
Port: 0
RAM: 128 MB
Instruction on WordPress Litespeed:
In the „Host” field paste address from the panel, for example: /home/klient.dhosting.pl/dhtutorial/.redis/redis.sock
In the „Port” field remove a default value and type "0".
Leave "user" and "password" empty.
It seems like everything works correctly in a direct use of Redis, but not via console. Anyone has an idea how to fix it?
Thanks in advance, I have searched whole Internet.
REDIS_HOST should point to the address where the Redis server is hosted whether it's hosted on a local machine or cloud service. somethings like below:
REDIS_HOST=12.0.0.1
REDIS_PASSWORD=password
REDIS_PORT=6379
set REDIS_HOST=127.0.0.1 or your host address
Try to use the following configuration.
.env
CACHE_DRIVER=redis
SESSION_DRIVER=redis
REDIS_SCHEME=unix
REDIS_PATH=/path/.redis/redis.sock
REDIS_CACHE_DB=0
REDIS_SESSION_DB=1
config.database.php
'redis' => [
'client' => env('REDIS_CLIENT', 'predis'),
'cluster' => true,
'options' => [
'cluster' => env('REDIS_CLUSTER', 'predis'),
'prefix' => Str::slug(env('APP_NAME'), '_').'_',
'parameters' => ['password' => null],
],
'default' => [
'scheme' => env('REDIS_SCHEME'),
'path' => env('REDIS_PATH'),
'database' => env('REDIS_CACHE_DB', 0)
],
'cache' => [
'scheme' => env('REDIS_SCHEME'),
'path' => env('REDIS_PATH'),
'database' => env('REDIS_CACHE_DB', 0),
],
'session' => [
'scheme' => env('REDIS_SCHEME'),
'path' => env('REDIS_PATH'),
'database' => env('REDIS_SESSION_DB', 1),
]
]
I'm building a CRM system which should allow a different access for different users, so i need to make a complex authentication and notifications in the panel. But the main system should use the REDIS. I have installed yii2 redis plugin and have the config like this in db.php (mysql config ):
<?php
return [
'class' => 'yii\db\Connection',
'dsn' => 'mysql:host=localhost;dbname=yii2basic',
'username' => 'root',
'password' => '',
'charset' => 'utf8',
// Schema cache options (for production environment)
//'enableSchemaCache' => true,
//'schemaCacheDuration' => 60,
//'schemaCache' => 'cache',
];
And in web.php:
$db = require __DIR__ . '/db.php';
$config = [
'id' => 'basic',
'basePath' => dirname(__DIR__),
'bootstrap' => ['log'],
'aliases' => [
'#bower' => '#vendor/bower-asset',
'#npm' => '#vendor/npm-asset',
],
'components' => [
'redis' => [
'class' => 'yii\redis\Connection',
'hostname' => 'localhost',
'port' => 6379,
'database' => 0,
],
],
'db' => $db,
How can i differntiate my models, to use either mysql or redis? I assume if i specify redis in components section, the whole app uses redis db. I could use redis with multiple values for key, but since redis is dropping the keys when max memory will be reached, all registered users and their profiles will parish, so i think i should use mysql for this basci stuff ( database with roles, authentification, profiles)
return [
'components' => [
'db1' => [
'class' => 'yii\db\Connection',
'dsn' => 'mysql:host=localhost;dbname=db1name', //maybe other dbms such as psql,...
'username' => 'db1username',
'password' => 'db1password',
],
'db2' => [
'class' => 'yii\redis\Connection',
'dsn' => 'YOURCONFIG',
'port' => '6379',
'password' => 'db2password',
'username' => 'db2username',
],
],
];
Then try to use
// To get from db1
Yii::$app->db1->createCommand((new \yii\db\Query)->select('*')->from('tbl_name'))->queryAll()
// To get from db2
Yii::$app->db2->createCommand((new \yii\db\Query)->select('*')->from('tbl_name'))->queryAll();
For active record in your model write
// db1
public function getDb() {
return Yii::$app->db1;
}
//Or db2
public function getDb() {
return Yii::$app->db2;
}
I have memcached selected as my cache driver. However , ran into a weird issue.
Once I am doing:
Cache::put('name','John',15);
In the very next line if I give
var_dump(Cache::get('name'))
it shows me :
bool(false)
Couldn't understand what's going wrong here. I have memcached running on port 11211 on my localhost which I can telnet.
Also phpinfo() shows php-memcached library is installed.
My config/cache.php file reads:
'default' => env('CACHE_DRIVER', 'memcached'),
'stores' => [
'apc' => [
'driver' => 'apc',
],
'array' => [
'driver' => 'array',
],
'database' => [
'driver' => 'database',
'table' => env('CACHE_DATABASE_TABLE', 'cache'),
'connection' => env('CACHE_DATABASE_CONNECTION', null),
],
'file' => [
'driver' => 'file',
'path' => storage_path('framework/cache'),
],
'memcached' => [
'driver' => 'memcached',
'servers' => [
[
'host' => env('MEMCACHED_HOST', '127.0.0.1'), 'port' => env('MEMCACHED_PORT', 11211), 'weight' => 100,
],
],
],
'redis' => [
'driver' => 'redis',
'connection' => env('CACHE_REDIS_CONNECTION', 'default'),
],
],
'prefix' => env('CACHE_PREFIX', 'laravel'),
Please help.
You have a typo. The method to set a value in the cache is put(), but you used get() twice. Try this:
Cache::put('name','John',15);
Finally after an entire day of Googling , I found the solution.
It seems I had to add the following line to bootstrap/app.php :
$app->configure('cache');
Also , please note that if you are running your application inside a VM/docker container , you need to provide the Host ip .
i spent 3 hours figuring out why my code was not working and can’t get the data from the cache and finally i figured out why :
Cache::put('name','John',15);
and when you do that You put that on the Cache for Only 15s or maybe 15ms depends on your configuration on the code.
You have to also check if you have permission on the storage Folder :
sudo CHOWN -R www:data:www:data storage
You can verify that you inserted the data on cache manually and you will see that you already cached that data but the expire date ttl is expired.
Good luck
In yii2 I need to use memcache plugin I've installed this also will be shown in phpinfo but I get the following error when running the project:
Invalid Configuration – yii\base\InvalidConfigException - MemCache requires PHP memcache extension to be loaded.
Cache configuration
'cache' => [
'class' => 'yii\caching\MemCache',
'servers' => [
[
'host' => '127.0.0.1',
'port' => 11211,
'weight' => 60,
],
],
]
Maybe you have got memcached instead of memcache. Configuration in this case should be:
'cache' => [
'class' => 'yii\caching\MemCache',
'useMemcached' => true, // <--- here
'servers' => [
[
'host' => '127.0.0.1',
'port' => 11211,
'weight' => 60,
],
],
],
Hello guy's I newbie in cakephp 3.0. I know little bit cakephp 2.0. I configured my redis with cakephp 2.0 with this help of url But I don't know how to configure in cakephp 3.0 please help me
Since Cakephp 4 is out, I am currently studying it (which seems exists in Cakphp 3 as well) and seems like there is a way to do it. Not tested yet.
Following this: https://book.cakephp.org/4/en/development/sessions.html#cache-sessions
app.php
'Session' => [
'defaults' => 'cache', //Use the Cache class to save session
'handler' => [
'config' => 'session'
]
],
Following this link: https://book.cakephp.org/4/en/core-libraries/caching.html#redisengine-options
app.php
/*
* Configure the cache adapters.
*/
'Cache' => [
'session' => [
'className' => RedisEngine::class,
//`port` The port your Redis server is running on.
//`host` The host your Redis server is running on.
//`database` The database number to use for connection.
//`password` Redis server password.
//`persistent` Should a persistent connection be made to Redis.
//`timeout` Connection timeout for Redis.
//`unix_socket` Path to a unix socket for Redist.
],
],
I am going to test this out later on and make update if needed, but it really seems promising.
Update 2020-05-20: Tested, it work fine
You would set your session to use cache sessions inside the app.php file:
'Session' => [
'defaults' => 'cache'
]
Then, you would set your cache to redis:
'Cache' => [
'default' => [
'className' => 'Redis',
],
]
In vendor\cakephp\cakephp\src\Network\Session.php
you can see the default type of session.
They are listed as php, cake,cache , database.
$defaults = [
'php' => [
'cookie' => 'CAKEPHP',
'ini' => [
'session.use_trans_sid' => 0,
]
],
'cake' => [
'cookie' => 'CAKEPHP',
'ini' => [
'session.use_trans_sid' => 0,
'session.serialize_handler' => 'php',
'session.use_cookies' => 1,
'session.save_path' => TMP . 'sessions',
'session.save_handler' => 'files'
]
],
'cache' => [
'cookie' => 'CAKEPHP',
'ini' => [
'session.use_trans_sid' => 0,
'session.use_cookies' => 1,
'session.save_handler' => 'user',
],
'handler' => [
'engine' => 'CacheSession',
'config' => 'default'
]
],
'database' => [
'cookie' => 'CAKEPHP',
'ini' => [
'session.use_trans_sid' => 0,
'session.use_cookies' => 1,
'session.save_handler' => 'user',
'session.serialize_handler' => 'php',
],
'handler' => [
'engine' => 'DatabaseSession'
]
]
]
Here is cache using default config of Cache. Maybe you want to use defualt as a File Cache.
In app.php
create a new cache config
'redis' => [
'className' => 'Redis',
'server'=>'127.0.0.1',
'port'=>6379
],
Then you can use your new cache config here.
'Session' => [
'cookie' => 'herewego',
'ini' => [
'session.use_trans_sid' => 0,
'session.use_cookies' => 1,
'session.save_handler' => 'user',
],
'handler' => [
'engine' => 'CacheSession',
'config' => 'redis'
]
],
