[ckan-dev] redis and cluster installation

[dporto]

AFAIK redis is mandatory for 2.7.0

I want to install this version (2.7.0) in a cluster infrastructure
(high availability)
Currently, there're several ckan instances (wsgi+solr) sharing the
same postgresql database

Could anybody tell me how to deal with (redis) ?
Redis tasks should be executed in each ckan node or it should be only
executed in one node?

Thanks in advance
