ruby-on-rails – Rails 4：Procfile中指定的Unicorn,但Webrick被执行

我正在使用Rails 4.0.1并且我想将unicorn作为我的web服务器运行,但是当我执行rails s时,使用了Webrick(unicorn gem在我的Gemfile中,所以它不可能).

这是我的Procfile：

worker:  bundle exec rake jobs:work
web: bundle exec unicorn -p $PORT -c ./config/unicorn.rb

这是unicorn.rb文件：

worker_processes 2
timeout 30
preload_app true

before_fork do |server, worker|

  Signal.trap 'TERM' do
    puts 'Unicorn master intercepting TERM and sending myself QUIT instead'
    Process.kill 'QUIT', Process.pid
  end

  defined?(ActiveRecord::Base) and
    ActiveRecord::Base.connection.disconnect!
end

after_fork do |server, worker|

  Signal.trap 'TERM' do
    puts 'Unicorn worker intercepting TERM and doing nothing. Wait for master to sent QUIT'
  end

  defined?(ActiveRecord::Base) and
    ActiveRecord::Base.establish_connection
end

到底是怎么回事？谢谢！

rails服务器不使用您的Procfile;那是 foreman.用工头开始你的申请：

bundle exec foreman start

如果您希望rails服务器也使用Unicorn,您可以包含unicorn-rails gem.
