我正在使用 Ubuntu 18.04.1 LTS 配置新服务器 (droplet)。我安装了 apache 并配置了虚拟主机。服务器名称是www.speedysoftware.com这是 的值/etc/hostname。问题是，我试图重定向http://www.speedysoftware.com/到特定虚拟主机，但重定向到默认虚拟主机。另一方面，http://www.speedysoft.com/和http://www.speedy-software.com/重定向到正确的虚拟主机，该虚拟主机应与http://www.speedysoftware.com/
文件/etc/apache2/sites-available/000-default.conf：
<VirtualHost *:80>
# The ServerName directive sets the request scheme, hostname and port that
# the server uses to identify itself. This is used when creating
# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request's Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.

您可以看到http://www.speedy-soft.com/重定向到默认虚拟主机，这是正确的。配置有什么问题？
做出更改后，我通过 重新加载了设置sudo systemctl restart apache2。
关于重定向，在这种情况下，我不想重定向。我希望它们被视为单独的网站，尽管它们指向同一个虚拟主机。在其他情况下，我会重定向，例如我重定向http://www.speedypedia.org/到http://www.speedypedia.info/，然后我重定向http://ww.speedysoftware.com/（或任何其他子域，包括http://speedysoftware.com/） 到http://www.speedysoftware.com/。
更新- 我检查了一下http://ww.speedysoftware.com/，http://wwww.speedysoftware.com/和http://speedysoftware.com/都指向正确的虚拟主机。只有http://www.speedysoftware.com/没有引导至正确的虚拟主机。

我写信给 DigitalOcean 支持部门（顺便说一句，他们的支持服务很棒），他们回复说：
该服务器是 Apache，因此您可以访问支持 -S 标志的 apachectl 命令来转储已解析的设置，其中包括建立它们的 vhosts 和配置。
我apachectl -S从命令行运行并发现了问题：
*:80 is a NameVirtualHost
default server www.speedysoftware.com (/etc/apache2/sites-enabled/000-default.conf:1)
port 80 namevhost www.speedysoftware.com (/etc/apache2/sites-enabled/000-default.conf:1)
...
由于我没有ServerName在 中定义/etc/apache2/sites-available/000-default.conf，因此 droplet 名称被占用，这就是问题所在。因此我ServerName www.speedy-soft.com在此文件中添加了以下内容：
<VirtualHost *:80>
# The ServerName directive sets the request scheme, hostname and port that
# the server uses to identify itself. This is used when creating
# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request's Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.
ServerName www.speedy-soft.com

</VirtualHost>
# vim: syntax=apache ts=4 sw=4 sts=4 sr noet
然后重新启动 Apache。我apachectl -S再次运行：
*:80 is a NameVirtualHost
default server www.speedy-soft.com (/etc/apache2/sites-enabled/000-default.conf:1)
port 80 namevhost www.speedy-soft.com (/etc/apache2/sites-enabled/000-default.conf:1)
...
现在一切正常。
