Nginx 将所有网站重定向到另一个网站

我遇到了一些奇怪的问题。我的服务器上安装了 2 个 WordPress 网站。我将它们称为

example1.com, example2.com

所有 2 个网站均在 Nginx、PHP-7.2、MariaDB 和 Ubuntu 18.04 上运行。

example1.com运行良好。这是我安装的第一个网站。当我安装第二个网站时，它example2.com运行良好，直到安装完成。然而，过了一会儿，它开始向我显示一个空白的主页。所有标题都正常，只是网站空白。

当我输入时，example2.com/wp-admin它会将我重定向到example1.com/wp-admin。所有网站都可以在 中运行https。

这是我的nginx.conf。

我已经使用这些配置将所有版本的 URL 重定向到https://www。

我怎样才能不再看到这些空白页并同时停止重定向？

答案1

  1. 确保第二个 WordPress 网站上的 URL 设置正确。（example2.com）
  2. 创建一个简单的 phpinfo 页面以/var/www/example2.com/public_html确保 NGINX 将请求路由到正确的路径example2.com。
  3. 检查访问日志example2.com以确保所有请求均由此虚拟主机提供服务。

  4. 创建一个简单的 PHP 信息页面，以确保example2.com此虚拟主机满足所有 PHP 请求。

完成这些步骤后，你就会发现问题出在哪里。
