nginx - php-fpm 如果 nginx 文件夹中不存在 index.php 则禁止

亚历山德罗·坎东

我们正在尝试使用 kubernetes 在 GCP 上部署应用程序。我们只使用 PHP-FPM 创建一个容器/pod，另一个使用 NGINX。

我们进行了部署并且一切正常，但是当我们尝试获取名为 index.php 的“helloword”php 文件时，我们收到来自 NGINX 服务的错误 403 Forbidden。

所以我尝试进入 NGINX pod 并在 php 项目的根目录（ /var/www/html/symfony/public ）手动添加 index.php 。当我这样做时，NGINX 神奇地返回了 PHP-FPM 脚本，而不是在 pod 中创建的文件。为了让大家理解我附上NGINX配置

      server {
      index index.php index.html;
      server_name php-docker.local;
      error_log  /var/log/nginx/error.log;
      access_log /var/log/nginx/access.log;
      root /var/www/html/symfony/public;

      location ~ \.php$ {
          fastcgi_split_path_info ^(.+\.php)(/.+)$;
          fastcgi_pass symfony:9000;
          fastcgi_index index.php;
          include fastcgi_params;
          fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
          fastcgi_param PATH_INFO $fastcgi_path_info;
      }
  }

NGINX 服务器使用 kubernetes DNS 将请求重定向到 PHP-FPM 服务器 symfony:9000

是的，我还有一项服务可以让 NGINX 与 PHP-FPM 通信：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: symfony
  namespace: default
  labels:
    app: symfony

这是 ku8 的 nginx 清单：

我解决了这个 NGINX 配置。不是kubernetes的问题...

      server {
      server_name php-docker.local;
      error_log  /var/log/nginx/error.log;
      access_log /var/log/nginx/access.log;
      root /var/www/html/symfony/public;

      proxy_buffering off;

      location = /nginx-health {
          access_log off;
          return 200 "healthy\n";
      }

      location / {
          try_files $uri /index.php$is_args$args;
      }

      location ~ \.php {
          fastcgi_split_path_info ^(.+\.php)(/.+)$;
          fastcgi_pass symfony:9000;
          include fastcgi_params;
          fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
          fastcgi_param DOCUMENT_ROOT $document_root;
          internal;
      }
      location ~ \.php$ {
              return 404;
      }
  }
