nginx-php-fpm如果nginx文件夾中沒有index.php，則禁止

Question

我們正在嘗試使用kubernetes在GCP上部署應用程序。 我們僅使用PHP-FPM和NGINX創建一個容器/容器。

我們進行了部署並一切正常，但是當我們嘗試獲取名為index.php的“ helloword” php文件時，NGINX服務會收到錯誤403 Forbidden。

因此，我嘗試進入NGINX容器並在php項目（/ var / www / html / symfony / public）的根目錄下手動添加index.php。 當我這樣做時，NGINX神奇地返回了PHP-FPM腳本，而不是Pod內部創建的文件。 為了讓您理解，我附加了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服務器使用kubernetes DNS symfony:9000將請求重定向到PHP-FPM服務器

是的，我還提供一項服務，允許NGINX與PHP-FPM通信：

Answer 1

您需要為每個Kubernetes服務創建一個kubernetes服務，以描述應用程序的公開端口。 或者將容器放在同一個容器中，並使用localhost：9000

內部kube DNS看起來像my-svc.my-namespace.svc.cluster.local

您不需要服務中將描述的端口信息。

參見https://kubernetes.io/docs/concepts/services-networking/dns-pod-service/

Answer 2

我使用此NGINX配置解決。 不是Kubernetes問題...

      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;
      }
  }
