Apache 虚拟主机：HTTP 被重定向到默认的 Apache 站点

Question

我已经使用 Apache 虚拟服务器在 VPS 上托管了一个网站，因为我计划稍后在该 VPS 上托管更多网站。在我使用 LetsEncrypt Certbot 在其上安装 SSL 之前，虚拟主机一直正常工作。这样做之后，https://techkernel.org works fine, but the http variant, http://techkernel.org 被重定向到默认的 Apache 网页。虚拟主机配置工作不正常，它被定向到默认的 /var/www/html 目录。

如果您能告诉我如何修复它，使 HTTP 和 HTTPS 请求都重定向到 HTTPS 并显示正确的网站，那将非常有帮助。谢谢。

<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.

Answer 1

您已将您的配置粘贴为 sites-AVAILABLE 中的示例。您是否已将它符号链接到 sites-ENABLED 以实际启用它？

编辑 - 抱歉，这似乎没有必要。我的观点是您的 HTTPS 变体正在运行，并且位于单独的配置文件中。你的 HTTP 不是，这在我看来是因为你没有创建这个符号链接，因此 Apache 没有 "what you do when you receive a request on port 80 with the Host: header set to techkernel.org" 的配置，因此它正在进入默认站点。您的配置对我来说看起来非常好，只是 Apache 实际上没有使用它。

Answer 2

原来是 000-default.conf 搞砸了。只有在运行 apachectl -S 命令之后我才注意到它。在修复它（输入正确的 ServerName 和 DocumentRoot 以及一些 URL 重写条件）和 reloading apache2 之后，它完美地工作。

Answer 3

除了您可能在 000-default.conf 中发现的错误外，您的重写规则还存在以下问题：

RewriteEngine on
RewriteCond %{SERVER_NAME} =www.techkernel.org [OR]
RewriteCond %{SERVER_NAME} =techkernel.org
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,QSA,R=permanent]

应该是

RewriteEngine on
RewriteCond %{HTTP_HOST} ^(www\.)?techkernel.org
RewriteRule ^/(.*) https://%{HTTP_HOST}/ [NC,R=301,L]

如果设置了 UseCanonicalName On，

%{SERVER_NAME} 可能是来自 VirtualHost 配置的值。因此，无论访问者使用什么 URI，它都会重定向所有内容。如果这是意图，那么只需删除任何 RewriteCond 并使用

RewriteEngine on
RewriteRule ^/(.*) https://www.techkernel.org/ [NC,R=301,L]

如果问题得到解决，您 could/should 删除 .htaccess 中的所有相关条目

RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{SERVER_NAME}/% [R,L]
