Magento – use Redis as cache backend
We will configure Magento to use Redis as main cache backend.
1. Install Redis. (2.4 is required because it supports operating on multiple keys for many operations)
2. Install phpredis. For 2.4 support you must use the “variadic” branch: git checkout -t -b variadic origin/variadic, phpredis is optional, but it is much faster than Redisent.
3. Install this module git://github.com/colinmollenhour/Zend_Cache_Backend_Redis.git
4. Edit app/etc/local.xml to configure
Based on this article we have turned off cache disk :
<cache> <backend>Zend_Cache_Backend_Redis</backend> <slow_backend>database</slow_backend> <slow_backend_store_data>0</slow_backend_store_data> <auto_refresh_fast_cache>0</auto_refresh_fast_cache> <backend_options> <server>127.0.0.1</server> <port>6379</port> <database>database</database> <use_redisent>0</use_redisent> <!-- 0 for phpredis, 1 for redisent --> <automatic_cleaning_factor>20000</automatic_cleaning_factor> <!-- optional, 20000 is the default, 0 disables auto clean --> </backend_options> </cache>
To check if everything works fine you can use redis-cli :
flexishore@virtualbox:~$ redis-cli redis 120.0.01:6379> select database OK redis 127.0.0.1:6379> keys * 1) "zc:d:97a_REC_0000000510" 2) "zc:d:97a_REC_0000000511" 3) "zc:d:97a_REC_0000001240" 4) "zc:d:97a_REC_0000000512" .......
As you can see, there are a lot of cache indexes in Redis database.

Hi Rafal,
Its now some month since you tested redit as a backend for magento. How well did your tests go?
Can you eventually write a blogpost about redit and magento.
Best regards
Martin

I’ve implemented Redis on my Magento 1.6.1 store and have shared some thoughts on my blog: http://www.drewgillson.com/blog/using-redis-as-magentos-cache-backend/
