Question

无法连接到ipaddress：3000上的Rails服务器。端口3000在服务器上打开。从tcpdump可以看出，从浏览器获取的初始http是到达端口3000。

但WEBrick控制台中的任何活动都不会停在这里 -

=> Booting WEBrick
=> Rails 4.2.0 application starting in development on http://localhost:3000
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server
[2015-01-15 15:43:07] INFO  WEBrick 1.3.1
[2015-01-15 15:43:07] INFO  ruby 2.2.0 (2014-12-25) [x86_64-linux]
[2015-01-15 15:43:07] INFO  WEBrick::HTTPServer#start: pid=3072 port=3000

RVM或Rails没有明显的错误消息。

浏览器正在提供＆＃34;此网页不可用。＆＃34; 错误代码：ERR_CONNECTION_REFUSED

默认Gemfile -

source 'https://rubygems.org'

gem 'rails', '4.2.0'
gem 'sqlite3'
gem 'sass-rails', '~> 5.0'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.1.0'
gem 'execjs'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0', group: :doc

group :development, :test do
  gem 'byebug'

我做了什么来配置rails服务器 -

gpg --keyserver hkp://keys.gnupg.net --recv-keys D39DC0E3
\curl -sSL https://get.rvm.io | bash -s stable --ruby
source ~/.rvm/scripts/rvm

sudo yum install -y sqlite-devel.x86_64 libdbi-dbd-sqlite.x86_64 libxml2-devel.x86_64 libxslt-devel.x86_64 sqlite-devel

curl -sL https://rpm.nodesource.com/setup | bash -
yum install -y nodejs
yum groupinstall 'Development Tools'
wget http://nodejs.org/dist/node-latest.tar.gz
tar xvfvz node-latest.tar.gz

cd node-v0.10.35 
./configure
make
sudo make install

sudo yum install -y postgresql.x86_64 postgresql-devel.x86_64 postgresql-libs.x86_64

gem install rails
gem install sqlite3
rvm 2.2.0 do gem install jquery-rails
rails new <test_app>
rails server

一个简单的javascript服务器可以在同一个系统上运行。所以不是OS配置/防火墙问题。

此外，与Ruby 2.1.5和2.0.0相同，使用Rails 4.2.0和最新的稳定RVM。

这有效 -

rails server -b 0.0.0.0 -p 3000
