When I switched to the AWS Load balancer (multiple server), Session should be maintained unique. When I used to login my site the session lost and it redirected to the home page. So I have tried to store the session in DB using following code.
Configure::write('Session', array(
'defaults' => 'database',
'handler' => array(
'model' => 'cake_sessions'
)
));
But it used to store the session data when admin used to logout. I have tried to configure cake session handler interface its fails.
How to haddle the session and cache in database.
I don't know about the load balancer, but you can handle your sessions in serval ways, including using databases.
And this is the default configuration of CakePHP to use database for sessions.
First create this table :
CREATE TABLE `cake_sessions` (
`id` varchar(255) NOT NULL DEFAULT '',
`data` text,
`expires` int(11) DEFAULT NULL,
PRIMARY KEY (`id`)
);
Then, configure your sessions in app/core.php
Configure::write('Session', array(
'database' => array(
'cookie' => 'CAKEPHP',
'timeout' => 240,
'ini' => array(
'session.use_trans_sid' => 0,
'url_rewriter.tags' => '',
'session.use_cookies' => 1,
'session.cookie_path' => static::$path,
'session.save_handler' => 'user',
'session.serialize_handler' => 'php',
),
'handler' => array(
'engine' => 'DatabaseSession',
'model' => 'Session'
)
)
));

So I'm using beyondcode/laravel-websockets to setup a WS server and I want to work with multiple apps so I did this in config\websockets.php:
'apps' => [
[
'id' => env('A_APP_ID'),
'name' => env('A_APP_NAME'),
'key' => env('A_APP_KEY'),
'secret' => env('A_APP_SECRET'),
'path' => env('A_APP_PATH'),
'capacity' => null,
'enable_client_messages' => false,
'enable_statistics' => true,
],
[
'id' => env('B_APP_ID'),
'name' => env('B_APP_NAME'),
'key' => env('B_APP_KEY'),
'secret' => env('B_APP_SECRET'),
'path' => env('B_APP_PATH'),
'capacity' => null,
'enable_client_messages' => false,
'enable_statistics' => true,
],
],
However, I want to implement custom handlers for each app and I've been trying this, routes\web.php:
WebSocketsRouter::webSocket('app/{appKey}/bapp', \App\WebSockets\BAppWebSocketHandler::class);
//Also tried this..
WebSocketsRouter::webSocket('app/{appKey}', \App\WebSockets\AAppWebSocketHandler::class);
//and created `AAppWebSocketHandler` which does nothing but calling parent (WebSocketHandler) methods
Problem is it's always using one handler for all apps despite the difference in routes.
Any ideas?
Thanks!
You don't have to define routes while defining multiple apps in the config. Instead configure Echo to work with separate app key and secret. If you want to use custom handler with own logic, then remove them from configs. Also note that, you won't get any channel or pusher client library support. You will have to implement your own authentication as well.
I'm using zf2 apigility in my web application. With production mode, if config_cache_enabled is true in config/application.config.php, I get this message error when requesting access_token:
The storage configuration for OAuth2 is missing
If I set it to false, I get my access token.
So my problem is to have config_cache_enabled set to true and a successful request for getting the access token in production mode, due to best performance when configuration is cached. How to do that ?
This is my zf-mvc-auth configuration :
'zf-mvc-auth' => array(
'authentication' => array(
'adapters' => array(
'CustomStorage' => array(
'adapter' => 'ZF\\MvcAuth\\Authentication\\OAuth2Adapter',
'storage' => array(
'storage' => 'Application\\Adapter\\OAuth\\CustomPdoAdapter',
'route' => '/oauth',
),
),
),
),
),
This is my oauth2.local.php :
'zf-oauth2' => array(
'db' => array(
'dsn' => 'mysql:dbname=mydatabase;host=localhost',
'username' => 'root',
'password' => '',
),
'allow_implicit' => true,
'access_lifetime' => 3600,
'enforce_state' => true,
'storage' => 'Application\Adapter\OAuth\CustomPdoAdapter',
'storage_settings' => array(
'user_table' => 'users',
),
'options' => array(
'always_issue_new_refresh_token' => true,
),
),
I think it is well configured.
Did you setup your zf-mvc-auth correctly. In the module.config.php you can read that you have to define a storage key. There is also written how you can do this:
To specify the storage instance, you may use one of two approaches:
Specify a "storage" subkey pointing to a named service or an array
of named services to use.
Specify an "adapter" subkey with the value "pdo" or "mongo", and
include additional subkeys for configuring a ZF\OAuth2\Adapter\PdoAdapter
or ZF\OAuth2\Adapter\MongoAdapter, accordingly. See the zf-oauth2
documentation for details.
If you are on production mode and "config_cache_enabled" it's true, you need to delete files on data/cache folder
I'm trying to use an external cache engine, memcached, to power my CakePHP app.
I have an AWS EC2 instance running the app and also an AWS ElastiCache Cluster with one node using memcached. The memcache and memcached php modules are also installed and enabled.
The configuration in the app.php file is as follows:
'Cache' => [
'default' => [
'className' => 'File',
'path' => CACHE,
],
'elastic' => [
'className' => 'Cake\Cache\Engine\MemcachedEngine',
'compress' => false,
'duration' => '+2 minutes',
'groups' => [],
'host' => 'yyy.euw1.cache.amazonaws.com:11211',
'username' => null,
'password' => null,
'persistent' => false,
'prefix' => 'cake_',
'probability' => 100,
'serialize' => 'php',
'servers' => ['yyy.euw1.cache.amazonaws.com:11211'],
'options' => [],
'lock' => true
]
To select whether or not to query the database, this condition is used:
if (($car = Cache::read('car', 'elastic')) === false) {
$car = $this->Cars->get();
Cache::write('car', $car, 'elastic');
}
Unfortunately, after a long page load I get this error:
"elastic cache was unable to write to DebugKit\Cache\Engine\DebugEngine cache"
Does anyone knows the origin of this error? Can someone guide me through the configuration of memcached for cakephp, using an external cache engine?
Thank you upfront!
Thank you for your reply.
This issue is now closed. We had to allow IP access between EC2 and CloudCache Cluster.
I want to get the kohana session data outside the kohana application. I mean to say that i want to get the session data in a static file which is not a kohana page.
I have tried many things and atlast i have found the answer,
In your controller class, get the native session id before kohana session instance and store it. Now close the native session and initiate kohana session by passing the session id as an argument.
session_start();
// Store session id and close the session
$sessionId = session_id();
session_write_close();
// Then we can restore the session by using the session id
// and the Session class from Kohana
Session::Instance(Session::$default, $sessionId);
Now you can access the session inside the kohana application.
session_name('kohana'); //Your session name
print_r($_SESSION);
You can apply configuration settings to each of the session adapters by creating a session config file at APPPATH/config/session.php. The following sample configuration file defines all the settings for each adapter:
[!!] As with cookies, a "lifetime" setting of "0" means that the session will expire when the browser is closed.
return array(
'native' => array(
'name' => 'session_name',
'lifetime' => 43200,
),
'cookie' => array(
'name' => 'cookie_name',
'encrypted' => TRUE,
'lifetime' => 43200,
),
'database' => array(
'name' => 'cookie_name',
'encrypted' => TRUE,
'lifetime' => 43200,
'group' => 'default',
'table' => 'table_name',
'columns' => array(
'session_id' => 'session_id',
'last_active' => 'last_active',
'contents' => 'contents'
),
'gc' => 500,
),
);
I'm attempting to use the session database with Kohana 3.
I have setup the mysql database as described here: http://kerkness.ca/wiki/doku.php?id=sessions_and_cookies
I am setting session variables like so:
Session::instance('database')->set('uid', $user_id);
However when I go to fetch the data back later on a different page or refresh it returns NULL.
Session::instance('database')->get('uid', NULL);
But if I put them right next to each other it works fine... i.e.
Session::instance('database')->set('uid', $user_id);
Session::instance('database')->get('uid', NULL);
Any ideas as to why this is happening?
I have also setup session.php in my config folder which looks like this:
<?php
return array(
'cookie' => array(
'name' => 'cookie',
'encrypted' => TRUE,
'lifetime' => 43200,
),
'native' => array(
'name' => 'session',
'encrypted' => TRUE,
'lifetime' => 43200,
),
'database' => array(
'group' => 'default',
'table' => 'sessions',
),
);
?>
Cheers,
Thomas.
Update the session.php file to look like this:
<?php
return array(
'cookie' => array(
'name' => 'session_cookie',
'encrypted' => TRUE,
'lifetime' => 43200,
),
'native' => array(
'name' => 'session_native',
'encrypted' => TRUE,
'lifetime' => 43200,
),
'database' => array(
'name' => 'session_database',
'group' => 'default',
'table' => 'sessions',
),
);
?>
Problem was by default the sessions are called 'session'.
So I renamed each adapter and it has fixed the issue.
