ruby-on-rails - 如何配置 Rails 5.2.1 服务器监听所有接口(interface)？

Question

我对 RoR 和学习还很陌生，所以如果我有后续问题，请多多包涵。我们的 Rails (v 5.0.2) 应用程序配置为在 config/boot.rb 中使用此配置监听所有接口(interface):

require 'rails/commands/server'
module Rails
  class Server
    def default_options
      # make rails listen on all interfaces (accept connections from any ip)
      super.merge(Host: '0.0.0.0', Port: 1234)
    end
  end
end

我最近将 Rails 从 5.0.2 升级到 5.2.1，当我运行 rails s 时，我得到:

/Users/aum/rails_app/config/boot.rb:5:in `require': cannot load such file -- rails/commands/server (LoadError)
    from /Users/aum/rails_app/config/boot.rb:5:in `<top (required)>'
    from bin/rails:8:in `require_relative'
    from bin/rails:8:in `<main>'

所以我将 'require' 更新为 rails/commands/server/server_command 现在我得到了

rails s
/Users/aum/.rvm/gems/ruby-2.3.3@rails_app/gems/railties-5.2.1/lib/rails/commands/server/server_command.rb:110:in `<module:Command>': uninitialized constant Rails::Command::Base (NameError)
Did you mean?  Base64
  from /Users/aum/.rvm/gems/ruby-2.3.3@rails_app/gems/railties-5.2.1/lib/rails/commands/server/server_command.rb:109:in `<module:Rails>'
  from /Users/aum/.rvm/gems/ruby-2.3.3@rails_app/gems/railties-5.2.1/lib/rails/commands/server/server_command.rb:11:in `<top (required)>'
  from /Users/aum/rails_app/config/boot.rb:5:in `require'
  from /Users/aum/rails_app/config/boot.rb:5:in `<top (required)>'
  from bin/rails:8:in `require_relative'
  from bin/rails:8:in `<main>'

我不确定如何/在何处指定 Rails 5.2.1 中的主机和端口，因为 default_options 定义也已在此处更改:https://github.com/rails/rails/blob/master/railties/lib/rails/commands/server/server_command.rb#L68

注意:我可以使用 rails s -b 0.0.0.0 -p 1234 启动服务器，但这不是我想要做的。

预先感谢您的帮助!

假设您使用的是 puma ，这是 Rails 5 的默认 HTTP 服务器，绑定(bind)选项在 config/puma.rb 中定义:

bind 'tcp://0.0.0.0:3000'
