Nginx（Ubuntu 18.04）FastCGI 在 stderr 中发送：“主脚本未知”，同时从上游读取响应头

嗯...我知道有很多类似的问题。但为了让这篇文章在解决后对社区有用，我想列出一个适用于 Wordpress 的 Nginx + PHP-fpm conf 文件。但到目前为止，它不起作用，呵呵。

因为这是我第二次处理 Nginx（第一次设置接近默认设置）配置，恐怕我无法在没有帮助的情况下处理问题。我试图做的是设置 Nginx 和 FastCGI 缓存，以便击败 Wordpress 并使其运行得更快。安装后，nginx 能够在寻址时显示默认的问候 html 页面http://vps_ip_adress。我想这意味着网络和基本设置都很好。然后我安装了 php7.4-fpm 并调整了一些 nginx 配置以启用 FastCGI 缓存，以便进一步安装 Wordpress。为了测试目的，我把信息文件文件包含<?php phpinfo(); ?>到根目录 /var/www/html/mysitename/info.php。现在我进入了FastCGI sent in stderr: "Primary script unknown" while reading response header from upstreamnginx 错误日志。我已经读到这意味着 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，由于没有使用 nginx 的经验，我无法找到错误。

作为参考，我使用了在互联网上找到的 nginx 配置（是的……我知道，在互联网上找到的东西有问题——它从来都不起作用，呵呵）。如果在某人的帮助下，我可以让它工作，这里将列出使用 FAstCGI 缓存设置的 Nginx+PHP-fpm，我想这很受欢迎。任何关于如何为 Wordpress iptimize nginx+php-fpm 配置的建议都将不胜感激。

/etc/php/7.4/fpm/pool.d/www.conf 该文件中的一些亮点（很长......）

user = www-data
group = www-data
listen = 127.0.0.1:9000
listen.owner = www-data
listen.group = www-data
listen.mode = 0660

您能帮助我排除故障吗？

最后我通过以下设置使其工作...这是对我有用的配置。

先决条件。重要！

  • VPS 配置：Ubuntu 18.04，Nginx + Php7.4-fpm + MariaDB + PHPMyAdmin。如果你有相同的软件包，可以随意复制粘贴配置列表，呵呵
  • 在 Google Cloud 实例、Amazon EC2 和 Scaleway 上进行了测试。对于 scaleway，需要进行一些调整（例如默认情况下非 root 用户无法sudo在 Ubuntu 18.04 实例上运行命令等）
  • 如果你使用的是不同于 7.4 的 PHP-fpm 版本，请确保在配置中反映这一点
  • 这适用于使用 Letsencrypt SSL 的单站点配置（关于如何使用 CertBot 设置 Letsencrypt SSL 的很好的书面说明有很多）
  • 顺便说一句，如果您使用 Cloudflare，您可能会遇到重定向循环，ERRTOOMANY_REDIRECTS请确保在 Cloudflare 端也配置 SSL。
