生产环境错误

Question

首先,我是Rails的新手.我正在创建一个博客应用程序,当尝试在生产中运行它时,两种方式:

rails s -e production

和

RAILS_ENV=production

我犯了同样的错误:

=>引导的WEBrick =>的Rails 3.2.8应用开始在生产上http://0.0.0.0:3000
=>与-d呼叫脱离
=> Ctrl-C来关闭服务器
退出
/home/loku/.rvm/gems /ruby-1.9.3-p286/gems/activerecord-> resolve_hash_connection':数据库配置未指定适配器(ActiveRecord :: AdapterNotSpecified)
...

我的设置:

ruby 1.9.3p286 (2012-10-12 revision 37165) [i686-linux]

Rails 3.2.8

database.yml的:

development:    
  adapter: mysql2    
  encoding: utf8    
  reconnect: false    
  database: blogg_development    
  pool: 5    
  timeout: 5000    
  username: root    
  password: *** 
  host: localhost    

production:    
  adapter: mysql2       
  encoding: utf8    
  reconnect: false    
  database: blogg_production    
  pool: 5    
  timeout: 5000    
  username: root    
  password: ***    
  host: localhost

的Gemfile:

source 'https://rubygems.org'
ruby '1.9.3'
gem 'rails', '3.2.8'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'mysql2'

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'

  # See https://github.com/sstephenson/execjs#readme for more supported runtimes
  gem 'therubyracer', :platforms => :ruby

  gem 'uglifier', '>= 1.0.3'
  gem 'haml-rails'
  gem 'less-rails'
  gem 'twitter-bootstrap-rails', :git => 'git://github.com/seyhunak/twitter-bootstrap-    rails.git'
  #gem 'actionpack', '~> 3.1.0'
end

gem 'jquery-rails'
gem 'haml'
gem 'devise'
gem 'cancan'

group :test, :development do
  gem 'guard-livereload'
  gem 'rb-fsevent'
  gem 'pry'
  gem 'pry-rails'
end

group :linux do
  gem 'libnotify'
end

group :darwin do
  gem 'rb-fsevent', require: false
  gem 'growl'
end

您需要指定您忘记测试的所有环境，这可能就是发生错误的原因
