Php 适用于Windows和Symfony 4的Docker中的NGINX 502网关错误

我正在尝试在Windows机器上用NGINX和PHP-FPM在Docker中设置Symfony 3。目前，我得到一个502坏网关错误。我将FPM端口从9000更改为8000，因为在我的主机上，端口9000已被hyper-v服务vmms.exe使用。我不知道这是否有关系

docker-compose.yml

version: "3"

services:

  nginx:
      build: ./nginx
      volumes:
        - ./symfony:/usr/shared/nginx/html
      ports:
        - "80:80"
        - "443:443"
      environment:
        - NGINX_HOST=free-energy.org
      depends_on:
        - fpm

  fpm:
      image: php:fpm
      ports:
          - "8000:8000"
      # It seems like FPM receives the full path from NGINX
      # and tries to find the files in this dock, so it must
      # be the same as nginx.root
      volumes:
          - ./symfony:/usr/shared/nginx/html

version: "2"
services:
  nginx:
    build: "./docker/nginx/"
    container_name: "nginx-free-energy"
    volumes_from:
      - php-fpm
    restart: always
    ports:
      - "80:80"
  php-fpm:
    image: php:7.1-fpm
    container_name: "php-fpm-free-energy"
    volumes:
      - ./src/free-energy.org:/var/www/free-energy.org
    restart: always
    expose:
      - "9000"

Dockerfile NGINX：

FROM nginx:1.13.7-alpine

# Change Nginx config here...
RUN rm /etc/nginx/conf.d/default.conf
ADD ./default.conf /etc/nginx/conf.d/

EXPOSE 80
EXPOSE 443

default.conf覆盖NGINX：

server {
    listen  80;
    server_name free-energy.org;

    # this path MUST be exactly as docker-compose.fpm.volumes,
    # even if it doesn't exist in this dock.
    root /usr/share/nginx/html;

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

    location ~ ^/.+\.php(/|$) {
        fastcgi_pass fpm:8000;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }
}

您能检查一下php fpm容器吗？我记得，php fpm默认端口是9000，而不是8000。将容器内部的端口映射从8000更改为9000

或者，如果它已在主机上使用，则只能在容器之间公开端口

回答为0tshell\u n1ck时，502错误得到解决。我仍然在浏览器中找到“未找到文件”，在NGINX“从上游读取响应头时在stderr中发送的FastCGI:Primary script未知”中找到相关错误日志

以下是最终证明有效的配置。需要改变的关键事项：

NGINX配置文件中的root指令不包含Symfony项目中所需的/public，因为front controller index.php位于其中 我在docker-compose.yml中更改了卷目的地，使Symfony项目目录现在映射到/var/www/Symfony，而不是/usr/shared/nginx/html。我不确定为什么以前的目录不起作用 这些要点是在使用位于

这是有效的代码

docker-compose.yml：

version: "3"

services:

  nginx:
      build: ./nginx
      volumes:
        - ./symfony:/var/www/symfony

      ports:
        - "80:80"
        - "443:443"
      depends_on:
        - fpm

  fpm:
      image: php:fpm
      ports:
          - "9000"
      volumes:
          - ./symfony:/var/www/symfony

NGINX配置default.conf：

server {
    listen  80;
    server_name free-energy.org, www.free-energy.org;
    root /var/www/symfony/public;

    location / {
        # try to serve file directly, fallback to index.php
        try_files $uri /index.php$is_args$args;
    }

    location ~ ^/index\.php(/|$) {
        fastcgi_pass fpm:9000;
        fastcgi_split_path_info ^(.+\.php)(/.*)$;
        include fastcgi_params;
        # When you are using symlinks to link the document root to the
        # current version of your application, you should pass the real
        # application path instead of the path to the symlink to PHP
        # FPM.
        # Otherwise, PHP's OPcache may not properly detect changes to
        # your PHP files (see https://github.com/zendtech/ZendOptimizerPlus/issues/126
        # for more information).
        fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
        fastcgi_param DOCUMENT_ROOT $realpath_root;
        # Prevents URIs that include the front controller. This will 404:
        # http://domain.tld/index.php/some-path
        # Remove the internal directive to allow URIs like this
        internal;
    }

    # return 404 for all other php files not matching the front controller
    # this prevents access to other php files you don't want to be accessible.
    location ~ \.php$ {
        return 404;
    }

    error_log /var/log/nginx/project_error.log;
    access_log /var/log/nginx/project_access.log;
}

我们将在一周内猜测，尝试使用以下方法： /docker-compose.yml

      depends_on:
        - fpm

  fpm:

      # It seems like FPM receives the full path from NGINX

启动后，您需要将127.0.0.1 free-energy.org添加到您的/etc/hosts文件以解析主机，您的应用程序将位于/src/free-energy.org入口点为-/src/free-energy.org/web/app.php

谢谢，我将其改回9000。现在我得到了'FastCGI sent in stderr:“Primary script unknown'。如果您公开了端口，您是否更改了FastCGI_pass fpm:8000；fastcgi_通过fpm:9000；在您的NGINX默认配置中？也许你忘了重建图像？我知道这一点，并已改为fastcgi_pass fpm:9000，并使用docker compose up-build
