Memcache

Permalink
Is there a way to configure 5.7.x to use memcached as the caching backend? I'm trying to configure Concrete5 to run on Google AppEngine, and the only references I can find are for the 5.6 version of Concrete, which doesn't help too much, as the configuration is quite different now. When I start the app, it creates a Memcached folder in the root application folder. This is not writable at runtime on GAE.

Hi,

I am having the same issue. I have just upgraded our hosting to a cluster and it now breaks with the error:

mkdir(): Input/Output error.


It turns out they use memcache. So the file sessions don't work.

I have found a dirty workaround that changes the sessions to work via the database, but it is very slow for me.

1. Create a file /application/config/concrete.php (if it doesn't exist).
2. Add this:

return array(
    'session' => array(
        'handler' => 'database'
    )
);


Changing it to memcache or memcached doesn't appear to work.

Anyone with any advice on getting it to work with memcache?

You can see herehttps://github.com/concrete5/concrete5/blob/5.7.x/web/concrete/src/S... the session factory only check if the handler is set to database or not.
When it's other than database, it takes the 
NativeFileSessionHandler
, which only supports files as it seems....

It's a pretty big step back in my opinion.

I am having massive issues with new host. They use memcached and the sessions aren't working. Nightmare as i have just moved 21 sites to them.

I have seen this across more and more hosts now. So my default option is to change to using database sessions. (see above)

I originally reported it was slower, but further testing has shown minimal performance load.

Good luck!

i think this is when you are using a memcache server that is different form your own server, but i could be wrong.
