Actually it is easier to just use the Redis PECL extension and leave CakePHP
which is the default. Just install the extension with:
sudo pecl install redis
Provided everything compiled fine, follow the instructions to load the extension and then
just edit your
session.save_handler = redis session.save_path = "tcp://192.168.0.1:6379"
Now restart your webserver and refresh your CakePHP app. It should work out of the box.
To verify that it works you can use the
redis-cli. When you are at the redis prompt
monitor and leave the window open. Refresh again and you should see the GET and
SETEX calls managing the session.
That is the same thing this wrapper would do.
Hope this works for you.
Redis Session Store for CakePHP
Change the value of the Configure call so that it looks like this:
Redis on localhost
If you have a default Redis installation running on localhost you don't need to change anything. It will connect and take over.
To confirm that it does indeed write to Redis you can use
and refresh your browser. You should see some GET and SETEX calls.
Redis on a foreign host
If you run on a different host you have to add two config settings
core.php to setup the connection.
Configure::write('RedisSession.hostname', 'some.host.name'); Configure::write('RedisSession.port', 1337);
I've ran the core component tests with this store enabled (CakePHP 1.3.10).
The class comes with iRedis, a very lightweight Redis Library by Dan Horrigan. The library is embedded inside the source file, wrapped in a class_exists() condition. If you want to use your own version make sure to include it early or just delete the iRedis block. I leave that up to you. I wanted to keep this store small.
Garbage collection is handled by Redis. I use SETEX (expire) when writing
to the store. The key will delete itself when the session expires. You can
verify the remaining time with
I have no complex key-namespacing going on. The key however is prefixed with the session name ('Session.cookie' value) followed by the session_id()
The cookie.path is hardcoded to '/'
