Cache: [Obtenez /] Miss on Nginx Unicorn en production

Question

Je reçois un cache: [GET /] miss Message d'erreur pour mon application Rails 3.2.

J'utilise Nginx comme proxy sur Unicorn Server et je déploie avec Capistrano. Lorsque je commence le serveur, je reçois beaucoup d'erreurs de répétition comme celle ci-dessus. Capistrano précompile définitivement les actifs pendant le déploiement. J'inclus les fichiers de configuration ci-dessous (désolé d'être verbeux).

Des idées ou au moins un indice pour découvrir ce qui ne va pas?

application.rb

config.assets.enabled = true

production.rb

# Disable Rails's static asset server
# (Apache or nginx SHOULD already do this BUT THEY DON'T)
config.serve_static_assets = true

# Don't fallback to assets pipeline if a precompiled asset is missed
# If I disable this I don't get assets served at all
config.assets.compile = true

Deploy.rb

require 'bundler/capistrano'

set :application, "network"
set :rails_env, "production"
set :deploy_to, "/var/www/#{application}"
set :repository,  "/var/repo/#{application}.git".
set :branch, "master"

set :use_sudo, false
set :user, "root"

set :unicorn_conf, "#{deploy_to}/current/config/unicorn.rb"
set :unicorn_pid, "#{deploy_to}/shared/pids/unicorn.pid"

set :bundle_roles, [:app]
set :normalize_asset_timestamps, false

set :scm, :git

server "mydomain.ru", :app, :web, :db, :primary => true

namespace :deploy do
  task :restart do
    run "if [ -f #{unicorn_pid} ] && [ -e /proc/$(cat #{unicorn_pid}) ]; then kill -USR2 `cat #{unicorn_pid}`; else cd #{deploy_to}/current && bundle exec unicorn -c #{unicorn_conf} -E #{rails_env} -D; fi"
  end
  task :start do
    run "cd #{deploy_to}/current && bundle exec unicorn -c #{unicorn_conf} -E #{rails_env} -D"
  end
  task :stop do
    run "if [ -f #{unicorn_pid} ] && [ -e /proc/$(cat #{unicorn_pid}) ]; then kill -QUIT `cat #{unicorn_pid}`; fi"
  end
end

Answer 1

J'ai remarqué des messages similaires dans mes journaux de serveurs Web et j'ai remarqué que je devais faire savoir aux rails que je n'utilise pas de mise en cache dans config/environments/production.rb

config.action_controller.perform_caching = false

Answer 2

'config.action_controller.perform_caching' est défini sur false si vous exécutez en mode développement. Cet drapeau est normalement défini dans la config / * Environments / *. RB 'correspondant et la mise en cache est désactivée par défaut pour le développement et le test, et activée pour la production.
