使用Capistrano 3，Nginx，Puma，GitHub和RVM的Rails 4 API部署示例到Amazon EC2？

这个问题是相当古老的，但我有完全相同的设置：Capistrano 3，Puma和nginx，所以我认为它可能仍然有助于某人，特别是因为Puma现在是Rails 5的默认值。我的项目不是开源的，所以我不能指向一个Github公共存储库，但这里是我完整的Capistrano配置让任何人看看。 它已经完美地工作了好几个月了。

在EC2重新启动/创建新实例时，要在生产服务器上正确启动Puma，请在这里查看我的答案：

Puma重启使用EC2 + Rails + Nginx + Capistrano重启失败

如果有要求，我会增加我的答案，但是因为这很简单，所以我只是让你成为一个名单。 基本上，Capistrano 3和Puma 2.6足以让你走了：

1. 在production组中添加puma到Gemfile 。
2. 要求Capfile 'capistrano/puma' 。
3. 如果需要，在config/deploy.rb设置任何puma选项。
4. 运行cap puma:config将puma配置文件复制到服务器。
5. 运行cap <stage> deploy 。
6. 将nginx的上游设置为服务器的Puma配置中指定的套接字路径。
7. 重新启动nginx 。
