Raylar, Yolcu ve Memcached: Başlatma sırasında sunucu bulamıyor

Question

Birinin bir kullanıcı hatası olduğundan emin olduğum bir sorun konusunda bana yardımcı olabileceğini umuyorum.

Aşağıdaki yapılandırma ayrıntıları, tümleştirme, geliştirme ve qa dahil olmak üzere tüm diğer ortamlarda çalışır. Ancak, üretim sunucuları aşağıdaki hata vermek:

<ActionController::Session::MemCacheStore:0x2b45f6acb248> unable to find server during initialization. 

ben sunucudan memcached kutu sorunu ve koşmak 'istatistik', ben almak zorunda telnet olabilir:

Aşağıda yapılandırma vardır detayları ve stacktrace.

config/environment.rb (önemli parçaları):

config.action_controller.session_store = :mem_cache_store 
config.gem "memcache-client", :lib => 'memcache' 

config/ortamlar/production.rb:

config.cache_store = :mem_cache_store 

require 'memcache'

Answer 1

Sadece emin olarak ancak oturum yapılandırmasını CACHE sabitinize nereye yerleştirdiğinizi göremiyorum:

config.action_controller.session = { 
    :session_key => '_appname', 
    :secret  => 'secret', 
    :cache  => CACHE, 
    :expires  => 10 
} 

Bu, varsayılan yönlendirmelerin yerel bellekteki memcached deposunu aradığını düşündüğüm için qa/dev/testing için çalışabilir. Üretim sırasında memcached sunucu için farklı bir ip var gibi görünüyor. stacktrace olarak

Answer 2

3 satır var: 29

sen denedin mi

Bazı mücevher eksik gibi görünüyor

/var/www/oro/production/releases/20100528130253/config/environment.rb 29 
/usr/local//lib/ruby/site_ruby/1.8/rubygems/custom_require.rb 31 in `gem_original_require' 
/usr/local//lib/ruby/site_ruby/1.8/rubygems/custom_require.rb 31 in `require' 

, on line environment.rb inceleyin ?:

sudo gem install memcached 

Bu memcached çalışıyor mu?

sudo /etc/init.d/memcached start 

Answer 3

Memcached gem ile benzer sorunlar yaşadım ve dali'a geçti. Dali üzerinde geliştirme daha aktif görünüyor ve önemli ölçüde daha hızlı. Github sayfasındaki yönergeleri izledim ve yaklaşık on dakika içinde çalışmaya başladım.

Answer 4

Bana göre, bu benim memcache arka planımın 127.0.0.1 dinlemediğini, ancak localhost'la ilgiliydi. Init dosyasından -l localhost seçeneğini kaldırdıktan sonra mükemmel çalıştı. (Varsayılan, tüm cihazlarda dinlemektir.) İyi bir soru için iyi bir soru için
