如何在开发中更改 Rails 3 服务器的默认端口? [英] How to change Rails 3 server default port in develoment?

问题描述

在我的开发机器上，我使用端口 10524.所以我以这种方式启动我的服务器:

On my development machine, I use port 10524. So I start my server this way :

rails s -p 10524

有没有办法将默认端口更改为 10524，这样我就不必在每次启动服务器时附加端口?

Is there a way to change the default port to 10524 so I wouldn't have to append the port each time I start the server?

推荐答案

首先 - 不要编辑您的 gem 路径中的任何内容！会影响到所有的项目，以后会出很多问题...

First - do not edit anything in your gem path! It will influence all projects, and you will have a lot problems later...

在你的项目中这样编辑script/rails:

In your project edit script/rails this way:

#!/usr/bin/env ruby
# This command will automatically be run when you run "rails" with Rails 3 gems installed from the root of your application.

APP_PATH = File.expand_path('../../config/application',  __FILE__)
require File.expand_path('../../config/boot',  __FILE__)

# THIS IS NEW:
require "rails/commands/server"
module Rails
  class Server
    def default_options
      super.merge({
        :Port        => 10524,
        :environment => (ENV['RAILS_ENV'] || "development").dup,
        :daemonize   => false,
        :debugger    => false,
        :pid         => File.expand_path("tmp/pids/server.pid"),
        :config      => File.expand_path("config.ru")
      })
    end
  end
end
# END OF CHANGE
require 'rails/commands'

原理很简单 - 您正在修补服务器运行器 - 所以它只会影响一个项目.

The principle is simple - you are monkey-patching the server runner - so it will influence just one project.

更新:是的，我知道有一个包含 bash 脚本的更简单的解决方案:

UPDATE: Yes, I know that the there is simpler solution with bash script containing:

#!/bin/bash
rails server -p 10524

但是这个解决方案有一个严重的缺点——它很无聊.

but this solution has a serious drawback - it is boring as hell.
