【问题描述】:
我正在尝试使用多个域在同一个 VPS 上托管多个不同的 Rails 应用程序。我在 Ubuntu 10.10 上使用 Apache 2.2.17。对于 Apache,我有多个 vhost 文件,因此我可以轻松启用和禁用特定站点,而无需将它们注释掉或删除它们。此外,我还使用了 mod_rewrite,这样访问同一个 rails 应用程序的多个域似乎会访问同一个 URL,因此我不会因为重复内容而受到搜索引擎的打击。
我相信我的 DNS 设置正确。对于每个域,我都有一个 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 似乎立即匹配 www 子域而不检查它后面的附加 URL。更改 ServerAlias 无济于事。例如,使用我的设置,如果我输入davidheartsrachel.com,我会正确访问我的婚礼网站。但是,如果我使用www.davidheartsrachel.com,我会访问我的另一个网站,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。
我能够使其正常工作的唯一方法是在主 vhost 文件中使用 mod_rewrite 来重定向到婚礼网站 vhost 文件(你可以看到我在主 vhost 文件中有它,但它是出于此问题的目的已注释掉)。这对我来说似乎不合适?我应该获得另一个 IP 并使用 IP 虚拟主机而不是基于名称的虚拟主机吗?
当我执行apachectl -S 时,我得到以下信息:
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 是默认站点 - 但是,它不需要进行完整的字符串匹配来确定正确的站点吗?

如果您能想到任何可能有帮助的更多信息,请让我发布。
编辑:
让我试着澄清一下。在最本质的形式中,我的问题是:为什么要去 davidheartsrachel.com 会带你到 www.afewguyscoding.com 而 davidheartsrachel.com 会根据我上面的配置带你到 davidheartsrachel.com
