多个域，多个vhost，单独的rails应用程序

标签： ruby-on-rails apache dns vhosts

我正在尝试使用多个域在同一个VPS上托管多个不同的rails应用。我在Ubuntu 10.10上使用Apache 2.2.17。对于Apache，我有多个vhost文件，这样我就可以轻松启用和禁用特定站点，而无需将其注释掉或删除它们。另外，我也使用mod_rewrite，以便转到同一个rails应用程序的多个域看起来转到相同的URL，所以就重复内容而言，我不会使用搜索引擎。

我相信我的DNS设置正确。对于每个域，我有一个www子域以及一些特定于站点的子域，例如博客等。我看到的问题是Apache似乎与www子域匹配立即而不检查它背后的额外URL。改变ServerAlias什么都不做。例如，使用我的设置，如果我输入davidheartsrachel.com，我就会正确到达我的婚礼网站。但是，如果我使用www.davidheartsrachel.com，我会访问我的其他网站，即我的软件开发业务。 URL不会被重写;它保持为davidheartsrachel.com而不是afewguyscoding.com。

我能够正常使用它的唯一方法是在主vhost文件中使用mod_rewrite重定向到婚礼网站vhost文件（你可以看到我在主vhost文件中有这个，但它是为了这个问题的目的而注释掉了）。这对我来说似乎不合适？我应该获得另一个IP并执行IP vhost而不是基于名称的虚拟主机吗？

当我执行apachectl -S时，我得到以下内容：

VirtualHost configuration:
wildcard NameVirtualHosts and _default_ servers:
*:80                   is a NameVirtualHost
         default server afewguyscoding.com (/etc/apache2/sites-enabled/afewguyscoding.com:1)
         port 80 namevhost afewguyscoding.com (/etc/apache2/sites-enabled/afewguyscoding.com:1)
         port 80 namevhost blog.afewguyscoding.com (/etc/apache2/sites-enabled/afewguyscoding.com:69)
         port 80 namevhost lbbs.afewguyscoding.com (/etc/apache2/sites-enabled/afewguyscoding.com:84)
         port 80 namevhost davidheartsrachel.com (/etc/apache2/sites-enabled/davidheartsrachel.com:1)
         port 80 namevhost dhr.afewguyscoding.com (/etc/apache2/sites-enabled/davidheartsrachel_staging:1)
Syntax OK

我注意到afewguyscoding.com是默认网站 - 但是，是否必须进行完整的字符串匹配才能确定正确的网站？

修改

让我试着澄清一下。在最重要的形式，我的问题是：为什么去davidheartsrachel.com带你到www.afewguyscoding.com和davidheartsrachel.com根据我的配置带你到davidheartsrachel.com

2 个答案:

答案 0 :(得分：0)

在我的服务器上，我没有在主httpd.conf文件中定义主站点。我在单独的应用程序特定配置文件中执行所有虚拟主机。

我在主httpd.conf中唯一拥有的是NameVirtualHost *:80行

Here's a gist你可以尝试一种方式。我从主站点配置中删除了所有婚礼站点配置。我将它设置为davidstites.com，afewguyscoding.com和www.davidstites.com都重定向到www.afewguyscoding.com。其他领域（milehigh等）不受影响。我不确定你想要去哪里。

所有与婚礼相关的域名都会重定向到www.davidheartsrachel.com。

我确实注意到我认为你的主站点配置可能搞得一团糟。在设置目录权限的最后，您使用/ var / www / afewguyscoding / current / public目录而不是DocumentRoot的/ var / www / wpress。我在那里进行的修正是在第一份文件的第74行。

答案 1 :(得分：0)

答案是我错误地将ServerAlias下的条目与逗号分开：

ServerAlias rachelanddavid.net, rachelanddavidstites.com, rachelanddavidwedding.com, www.davidheartsrachel.com, www.rachelanddavidstites.com, www.rachelanddavidwedding.com, www.rachelanddavid.net

它应该是一个空间：

ServerAlias rachelanddavid.net rachelanddavidstites.com rachelanddavidwedding.com www.davidheartsrachel.com www.rachelanddavidstites.com www.rachelanddavidwedding.com www.rachelanddavid.net
