Apache vhost 加载不正确的文档根目录

Question

我的问题是 Apache 随机加载一个非默认虚拟主机而不是我要求它加载的域。我已经尝试了我在这个网站上找到的所有解决方案并通过搜索，但似乎没有任何东西可以解决这个问题。

背景:

这是一个托管在流行云平台上的虚拟服务器

全局 apache conf 文件不包含 VirtualHost 定义，并且正确包含以下配置文件(包括 sites-enabled/*.conf)

Ubuntu 16.04 上的 Apache 2.4

我将每个域都放在自己的 conf 文件中，但这也不起作用。

Apache 选择了 domain3.com 由于某种原因，作为默认值。

当我执行 curl localhost在服务器上，它返回 domain3.com 的内容。

下面的虚拟主机中唯一排除的是一些似乎不会导致任何问题的 SSL 定义。

ServerName 定义为 localhost在 apache.conf

以下虚拟主机保存在 /etc/apache2/sites-enabled/000-default.conf

服务器怪异？

我似乎无法真正停止 apache。执行service apache2 stop然后 service apache2 status会将进程识别为非事件状态，但我仍然可以加载 domain1/2/3.com 下的页面。就像我所做的任何事情都没有任何效果一样。

现在有 3 种访问 apache 的方法。有些似乎有效，有些则无效。 /etc/init.d/apache2 , service apache2 , apache2ctl .

它仅在大约 50% 的时间加载错误的站点。

我完全没有想法...

至于 Apache 选择一个随机站点:

当你这样做 curl localhost ，它很可能发送了一个没有 Host: 的 HTTP header 定义，因为它的行为类似于直接在浏览器中键入服务器的 IP。 Host: HTTP 请求中的 header 是 Apache 与 ServerName 匹配的字段。和 ServerAlias试图找到一个匹配来加载相应的DocumentRoot .

因此，在这种情况下，如果您没有默认主机设置，并且一个空的 Host: 进入，那么 Apache 将随机选择一个站点(我已经在我的开发服务器上重新创建了这个行为，只是为了验证)。

最好将 000-default.conf 设置为您的包罗万象，并在发生这种情况时决定要做什么，例如重定向到您的一个站点或一个简单的 php 文件，它只是回显一些平淡无奇的东西。然后为每个站点设置单独的 conf 文件以保持井井有条。

如果您的 DNS 记录正确指向您的服务器，那么默认设置只会在机器人出现测试 IP 时触发。
