我在旧的 Ubuntu 服务器上有一个 rails 应用程序,我需要将其移到新机器上。
我没有使用过 ruby on rails,所以我对该应用程序的结构并不十分了解。
我想将其加载到 Amazon EC2 上的 Ubuntu 8.04 AMI 上,并正在寻找有关迁移过程的任何信息,例如:
我是否要复制 mongrel 配置中定义为应用程序根目录的整个文件夹(例如:/u/apps/myapp/current)还是仅复制某些文件夹?
如果我使用最新版本的 ruby 和各种 gem 是不是会自找麻烦?
在此过程中要注意哪些常见问题。

将整个事情放在当前形势下考虑。
您当前的站点可能正在使用 Capistrano 进行部署。如果是这样,您可能需要调查一下。如果这是您负责的事情,并且之前的人不再可以聊天,那么您也需要尝试发现更多信息:
- 这个版本有控制吗?
- 使用过 Capistrano 吗?
- 数据库是否也移动并设置在新主机上?
如果是标准 Rails 设置,数据库可能被命名为 application_production。
另外,查看 config/environment.rb 中可能需要安装的其他内容。该版本的 Rails 相当旧,但应该仍然可以通过它进行安装,gem install
因为您似乎已经设法做到了。
