文件夹重定向到子域 [英] Redirect folder to subdomain

问题描述

我想有2的Ruby on在域Rails应用程序。

I want to have 2 Ruby on Rails applications on a domain.

第一个是在 example.com 运行;我这样做，是用的.htaccess（与重写规则，以 example.com:12001 ）

The first one is running at example.com; I have done that with .htaccess (with RewriteRule to example.com:12001)

我想另一个是在一个子域名，如 blog.example.com 。所以，我创建了一个子域，并在该文件的.htaccess我重定向到 example.com:12002 。

I want the other one to be in a subdomain, like blog.example.com. So I created a subdomain, and in the file .htaccess I redirect to example.com:12002.

一切工作正常，但如果我去解决 example.com/blog ，我不是重定向，我在浏览器中看到博客的文件夹中的public_html的内容

Everything is working fine, but if I go to address example.com/blog, I am not redirected, and I see in browser the contents of blog folder in public_html:

Index of /blog

    Parent Directory

我想转到第二个应用程序（blog.example.com <$ C C $>）当网址 example.com/blog 。我怎么能这样做呢？

I would like to go to the second application(blog.example.com) when the url is example.com/blog. How could I do that?

推荐答案

解决方案取决于您的托管服务提供商实现多子域映射。有些提供的控制面板，让您可以注册子域，每个指向您的文件空间中的单独的子目录。有的将映射 *。yourdomain.zzz 文档根目录的 yourdomain.zzz ，并从你的描述，这种是正在发生的事情给你。在这种情况下，你需要去code在 HTTP_HOST 变量和路径上。但是你也需要停止你的重写规则的循环，使 sub1.yourdomain.zzz 不被映射到yourDocRoot / SUB1 / SUB1 / SUB1 ...`

the solution depends on how your hosting provider implements multi-subdomain mapping. Some offer a control panel so that you can register your subdomains and point each to a separate subdirectory in your file space. Some will just map *.yourdomain.zzz to the document root for yourdomain.zzz, and from your description, this is what is happening for you. In this case you need to decode the HTTP_HOST variable and route on that. But you also need to stop your rewrite rule looping so that sub1.yourdomain.zzz doesn't get mapped to yourDocRoot/sub1/sub1/sub1...`

如果你想处理的 SUB1 和 SUB2 的子域，那么你可以这样做，在你的规则顶层是这样的：

If you wanted to process sub1 and sub2 subdomains, then you would do this with a rule in you top level like this:

RewriteBase  /
RewriteCond  %{ENV:REDIRECT_INSUB} !=1
RewriteCond  %{HTTP_HOST}          (sub1|sub2)\.yourdomain\.zzz
ReweriteRule ^(.*)                 %1/$1         [L,E=INSUB:1]

搜索 [的.htaccess] HTTP_HOST 即可看到大量的这种变体。

Search for [.htaccess] HTTP_HOST to see lots of variants of this.
