Nginx（Ubuntu 18.04）FastCGI 在标准错误中发送：“主要脚本未知”，同时从上游读取响应标头

嗯...我知道有很多类似的问题被问到。但是为了使这篇文章在解决后对社区有所帮助，我想列出一个适用于 Wordpress 的 Nginx + PHP-fpm conf 文件。但截至目前它不起作用，他他。

因为这是我第二次处理 Nginx（第一次设置接近默认设置）配置，所以恐怕我无法在没有帮助的情况下处理故障排除。我要做的是使用 FastCGI 缓存设置 Nginx，以便踢 Wordpress 的屁股，使其运行得更快。安装 nginx 后，就可以在寻址时显示默认的问候语 html 页面http://vps_ip_adress。我想这意味着网络和基本设置很好。然后我安装了 php7.4-fpm 并调整了一些 nginx 配置以启用 FastCGI 缓存以进行进一步的 Wordpress 安装。出于测试目的，我将包含info.php文件<?php phpinfo(); ?>放入父亲根目录 /var/www/html/mysitename/info.php。现在我得到FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream在 nginx 错误日志中。我已经读过这意味着 php-fpm 无法找到脚本，很可能是由于 nginx 配置中的脚本名称错误。不幸的是，我没有使用 nginx，我找不到错误。

作为参考，我使用了在互联网上找到的 nginx 配置（是的......我知道，在互联网上发现的东西有问题 - 它永远不会工作，他）。万一在有人的帮助下，我会在这里工作，将列出 Nginx+PHP-fpm 设置与 FAstCGI 缓存，我猜这是非常需要的。任何有关如何为 Wordpress 优化 nginx+php-fpm 配置的建议都将不胜感激。

你能帮我解决问题吗？
