Question

我无法将基本的rails应用程序（适用于本地计算机，适用于heroku）部署到分布式体系结构（一个盒子上的Web服务器，另一个盒子上的数据库服务器）。

这是我的问题。似乎Capistrano无法更新数据库服务器上的缓存副本。

当然，无论你在哪里看到 app server ip ，或数据库ip 我都有这些服务器的实际ips。有什么想法吗？

Answer 1

如果服务器位于同一数据中心，您可以使用Linode Manager中列出的专用IP地址在两台服务器之间进行通信，而无需带宽成本。根据您的操作系统，您可能需要一个软件防火墙来打开端口以进行通信。

如果您尚未设置IP地址，请查看https://library.linode.com/remote-access#sph_adding-private-ip-addresses，其中包含有关如何添加IP地址的更多信息。

在单独的应用服务器和数据库服务器（均为Linode）上部署rails app
