反向代理混乱 [英] reverse proxy confusion

问题描述

目前，我使用Nginx + passenger服务我的Rails应用程序.我一直在对反向代理进行一些研究，并弹出了一些名称(大多数是鱿鱼，清漆和Nginx).

Currently I use nginx + passenger for serving my rails app. I have been doing some research on reverse proxies and a few names pop up (squid, varnish and nginx mostly).

1. 现在如果我使用nginx作为我的 网络服务器我是否可以将其用作我的服务器 反向代理?

1. Now If I am using nginx as my web server can I stil use it as my reverse proxy?

一般意义是 网站使用Nginx代理静态 内容和apache/杂种或 像这样的动态 内容.如果我想坚持我的 nginx，乘客设置，会怎样 我的建筑看起来像当我 引入反向代理?会吗 是一个单独的盒子或实例 nginx?

The general sense is that most sites use nginx for proxying static content and apache/mongrel or something like that for dynamic content. If I wanna stick with my nginx, passenger setup, what would my architecture look like when I introduce a reverse proxy? Will it be a separate box or instance of nginx?

如果我是什么样子 引入类似的负载均衡器 HAProxy.

What would it look like if I am introducing a load balancer like HAProxy.

最后，这些有多重要 提早选择?所以如果我结束 后悔一个选择(假设 清漆，因为效果不好 与饼干等)，这很容易 换东西了吗?

Finally, how important are these choices early on? So If I end up regretting a choice (let's say Varnish because it doesn't do well with cookies etc etc), is it easy to switch things around?

谢谢

推荐答案

反向代理是一台服务器，位于实际应用程序(轨道)和客户端浏览器之间，并代表客户端检索文件.配置反向代理仅需要在客户端和应用之间设置服务器.由于您已经在使用nginx，因此也可以将其用作反向代理.

A reverse proxy is a server that sits between your actual app (rails) and the client's browser, and retrieves files on behalf of the client. What is needed to configure a reverse proxy is only to set up a server between the client and the app; since you are already using nginx you can use it as a reverse proxy also.

1 :这是SO上的链接: nginx既是反向代理又是Web服务器

1 here's a link on SO: nginx be both reverse proxy and web server

2 您可以在同一实例中设置反向代理，也可以不在同一实例中设置.如果它是不同的盒子或流程，则需要将动态请求从一个盒子传递到另一个盒子.

2 You can set up a reverse proxy in the same instance or not. If it is a different box or process, you'll need to pass dynamic requests from one box to another.

4 ，如果您同时熟悉HTTP和配置这些服务器，我认为这很容易.我在Apache上遇到了困难，只是因为我错过了结尾的斜杠

4 I think it's fairly easy, if you are familiar with both HTTP and configuring those servers. I had a hard time with apache just because I missed a trailing slash
