I am a previous CakePHP 2 user and am starting a new application using CakePHP3, I have searched but am finding very little examples and/or detailed instructions on the configuration of Memcached for my application.

In CakePHP 2 I simply created a Cache configuration like:

> Cache::config(‘5m’, array(  
> ‘engine’ =\> ‘Memcached’,  
> ‘duration’ =\> 3600,  
> ‘servers’ =\> array(‘127.0.0.1:11211’)));

I am unable to find an example that is equivalent to this for CakePHP 3. I have tried using:

> ‘Cache’ =\> [  
> ‘5m’ =\> [  
> ‘className’ =\> ‘Memcached’,  
> ‘duration’ =\> ‘+5 minutes’,  
> ‘servers’ =\> ‘127.0.0.1:11211’  
> ],

However I receive “ **Cache engine Cake\Cache\Engine\MemcachedEngine is not properly configured.** ” error which tells me almost nothing on what needs to be adjusted. I am sure this is a simple configuration / syntax issue on my part, however, I am unable to find a full working example or description on how to get memcached usable in CakePHP 3.

- I know Memcached is installed correctly and running as all of my CakePHP 2 applications are using it just fine.

- I’d prefer to not use the DSN format.

Any help is appreciated.

The config i use is:

```
'flags' => [
    'className' => 'Cake\Cache\Engine\MemcachedEngine',
    'prefix' => 'flags_data_',
    'path' => CACHE . 'flags/',
    'duration' => '+10 seconds'
]

```

Hope it helps you.

‘prefix’ =\> ‘flags\_data\_’,  
‘path’ =\> CACHE . ‘flags/’,  
‘duration’ =\> ‘+10 seconds’  
]);

I have update my code to the lastest cakephp 3 in my app.php but still not working. I installed memcache and memcached in my centos server. Cakephp 2 its working fine but in cakephp 3 its not working throws error **Cache engine Cake\Cache\Engine\MemcachedEngine is not properly configured.**

```
  'Cache' => [
   
   'default' => [
        'className' => 'Cake\Cache\Engine\MemcachedEngine',
    ],

     */
    '_cake_core_' => [

@rpuerto

Please clarify what you mean by it’s not working. What error do you see, what else have you tried?

Do you have memcached installed and running, and what is the memcached instances settings (Specifically host and port)

Just saw your edit.

So, the reasons that memcached will throw that error are:

- The `memcached` php extension is not installed (Be careful here, Cake 2.x could use the old `memcache` extension, it’s possible you don’t have the correct one installed)
- The `memcached` servers are not available

I see this error **Warning (512): Cache engine Cake\Cache\Engine\MemcachedEngine is not properly configured. in [/home/apidata/public\_html/vendor/cakephp/cakephp/src/Cache/Cache.php, line 177]**

Memcache is already installed in our server.

Ah, there is your problem 🙂 CakePHP 3.x requires the new `memcached` extension, not the old `memcache` extension.

Glad I could help 🙂

You can/should also switch Cake 2.x to use `memcached`, it is faster than the old one.
