ruby on rails - Vagrant+Ansible+Redis - Get 127.0.0.1:6379 (Errno::ECONNREFUSED) when using different servers -

hope well. have following problem , hoping me out:

i'm trying deploy rails 4 app using vagrant , ansible. part of app redis server. have set , running @ 192.168.33.2:6379, rails app running @ 192.168.33.4 , running on ubuntu + nginx.

even-though have redis set redis-rb (gem in app) , initialize redis object in 1 of initializers app global vars initiated yaml file:

$redis = redis.new(:driver => :hiredis, :host => app_config[:redis_host], :port => app_config[:redis_port]) 

with app_config[:redis_host] = 192.168.33.2, app_config[:redis_port] = 6379

and bind 0.0.0.0 in redis.conf file, still receive error error connecting redis on 127.0.0.1:6379 (errno::econnrefused) when go rails app in browser.

running redis-cli -h 192.168.33.2 ping when vagrant ssh-ed 192.168.33.4 returns pong. connections can made , can reach redis server / see keys 192.168.33.4...

also running netstat -l in terminal gives me: tcp 00 *:6379 *:* listen

does know how can fix problem?

thanks in advance!

update

note: make use of redis-rails gem , use in app session_store & cache_store. (when not using redis works). configured in way:

#config/initializers/session_store.rb myapp::application.config.session_store :redis_store, {              :host => app_config[:redis_host],              :port => app_config[:redis_port],              :db => app_config[:redis_db],              # :password => "mysecret",              :namespace => "_myapp_session"}, :expires_in => 90.minutes  #config/application.rb config.cache_store = :redis_store,"redis://192.168.33.2:6379/12/api_cache", { expires_in: 3.minutes }

so able fix this, using one-liner approach:

myapp::application.config.session_store :redis_store, servers: "redis://#{app_config[:redis_host]}:#{app_config[:redis_port]}/#{app_config[:redis_db]}/myapp_session", key: '_myapp_session', :expires_in => 90.minutes 

please note servers: accidentally left out before. note key: '_myapp_session' important add (and match cache namespace in redis uri?) otherwise "can't verify csrf token authenticity" error when trying connect api.
