redis-rails provides a full set of stores (Cache, Session, HTTP Cache) for Ruby on Rails. See the main redis-store readme for general guidelines.
Add the following to your Gemfile:
gem 'redis-rails'To use with Rails 3.1+, pin the gem to the latest 4.0 version:
gem 'redis-rails', '~> 4'# config/application.rb
config.cache_store = :redis_store, "redis://localhost:6379/0/cache", { expires_in: 90.minutes }Configuration values at the end are optional. If you want to use Redis as a backend for sessions, you will also need to set:
# config/initializers/session_store.rb
MyApplication::Application.config.session_store :redis_store, servers: "redis://localhost:6379/0/session"You can also provide a hash instead of a URL
config.cache_store = :redis_store, {
host: "localhost",
port: 6379,
db: 0,
password: "mysecret",
namespace: "cache"
}And similarly for the session store:
MyApplication::Application.config.session_store :redis_store, servers: { host: "localhost",
port: 6379,
db: 0,
password: "mysecret",
namespace: "session"
},
expires_in: 90.minutesAnd if you would like to use Redis as a rack-cache backend for HTTP caching, add redis-rack-cache to your Gemfile and add:
# config/environments/production.rb
config.action_dispatch.rack_cache = {
metastore: "redis://localhost:6379/1/metastore",
entitystore: "redis://localhost:6379/1/entitystore"
}sentinel_config = {
url: "redis://mymaster/0",
role: "master",
sentinels: [{
host: "127.0.0.1",
port: 26379
},{
host: "127.0.0.1",
port: 26380
},{
host: "127.0.0.1",
port: 26381
}]
}
# configure cache, merging opts with sentinel conf
config.cache_store = :redis_store, sentinel_config.merge(
namespace: "cache",
expires_in: 1.days
)
# configure sessions, setting the sentinel config as the
# servers value, merging opts with the sentinel conf.
config.session_store :redis_store, {
servers: sentinel_config.merge(
namespace: "sessions"
),
expires_in: 2.days
