使用Rubber将Rails应用程序部署到EC2：503服务不可用

时间：2012-12-13 16:34:22

标签： ruby-on-rails ruby-on-rails-3 deployment amazon-ec2 passenger

所以我在过去几周一直在研究我的第一个（真正的）rails应用程序，昨天我尝试使用Rubber gem将其部署到Amazon EC2。在我部署我的实际项目之前，我对自己说：让我们在一个完全新鲜而简单的项目上尝试橡胶，看它是否有效。在执行了这个[railcast] [1]中的步骤后，一切都与简单项目一起工作。所以我尝试部署我的实际项目，执行与以前相同的步骤。橡胶执行所有Capistrano脚本，一切似乎进展顺利。但是，当我尝试访问该网站时，我收到此错误：503服务不可用

我使用了橡胶模板“complete_passenger_postgresql”。我成功部署的简单项目与实际项目之间的橡胶设置基本相同。不同之处在于应用的实际内容。

在查看日志文件后，我遇到了这些错误：

宝石“祖先”可能会导致这个问题吗？那么“Permission Denied”错误呢？

非常感谢你的帮助！

1 个答案:

答案 0 :(得分：0)

我设法通过以下方式解决了上述问题：

首先我给了rails项目的目录＆amp;通过申请

来申请适当的权利 
sudo chmod -R 777 ProjectDirectory

这解决了Apache权限错误。之所以出现这个问题，是因为我在另一台Windows和Linux机器上创建了该项目，并尝试将其部署在mac上。简单的测试项目有效，因为我在部署它的同一台机器上创建了它。

接下来，我将以下代码行添加到我的see.rb文件中，以摆脱“未初始化的常量ActiveRecord”错误：

require 'active_record'

经过这些调整之后，我再次使用橡胶部署了一切，并且它正在工作： - ）
