ruby-on-rails - 在不同的服务器上运行 unicorn 和 nginx

Question

大多数教程都展示了如何将 nginx Web 服务器配置为 unicorn ruby​​ 应用程序服务器的代理，当它们在同一台服务器上时；结果是它们都通过 unix 套接字进行通信。如果它们在不同的服务器上，我该如何配置它们。

Answer 1

unicorn designed只为快速客户服务:

unicorn is an HTTP server for Rack applications designed to only serve fast clients on low-latency, high-bandwidth connections and take advantage of features in Unix/Unix-like kernels. Slow clients should only be served by placing a reverse proxy capable of fully buffering both the the request and response in between unicorn and slow clients.

它如何在多节点环境之间进行负载平衡？答案是让应用程序节点 Nginx+Unicorn(通过 Unix Domain Socket 连接)和顶级 Nginx 作为单独节点上的负载均衡器。
