Bind rails server to 127.0.0.1 by default

问题

I'd like to bind the rails server to 127.0.0.1, instead of 0.0.0.0 so its not accessible when I'm working from coffee shops.

Is there a configuration file where I can specify this option so I don't have to pass the command line switch:

rails server -b 127.0.0.1

?

In Rails ~> 4.0 you can customize the boot section of the Server class:

In /config/boot.rb add this lines:

require 'rails/commands/server'

module Rails
  class Server
    def default_options
      super.merge({Port: 10524, Host: '127.0.0.1'})
    end
  end
end

You can make a bash script to just run the command by default:

#!/bin/bash
rails server -b 127.0.0.1

Put it in the same folder as your project, name it anything you want (e.g. devserv), then

chmod +x devserv

And all you have to do is ./devserv

I use Foreman as a process manager in development.

After adding gem 'foreman' to your Gemfile and running bundle install, create a file Procfile in the root of your application directory.

While you can add lines to manage other processes, mine just reads:

web: rails server -p $PORT -b 127.0.0.1

Then, to start the Rails server via the Procfile, run foreman start. If you have other processes here (Redis, workers) they'll boot at the same time.

If you put the default options on config/boot.rb then all command attributes for rake and rails fails (example: rake -T or rails g model user)! So, append this to bin/rails after line require_relative '../config/boot' and the code is executed only for the rails server command:

if ARGV.first == 's' || ARGV.first == 'server'
  require 'rails/commands/server'
  module Rails
    class Server
      def default_options
        super.merge(Host:  '127.0.0.1', Port: 10524)
      end
    end
  end
end

The bin/rails file loks like this:

#!/usr/bin/env ruby
APP_PATH = File.expand_path('../../config/application',  __FILE__)
require_relative '../config/boot'

# Set default host and port to rails server
if ARGV.first == 's' || ARGV.first == 'server'
  require 'rails/commands/server'
  module Rails
    class Server
      def default_options
        super.merge(Host:  '127.0.0.1', Port: 10524)
      end
    end
  end
end

require 'rails/commands'
