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

Question

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使用。exe。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

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

违约conf override 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;
    }
}

我们将这样猜测一周，尝试使用这个：/docker-compose.yml

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"

/docker/nginx/Dockerfile

FROM nginx

COPY config/free-energy.conf /etc/nginx/conf.d/free-energy.conf

RUN rm /etc/nginx/conf.d/default.conf

RUN usermod -u 1000 www-data

EXPOSE 80

CMD ["nginx", "-g", "daemon off;"]

/docker/nginx/config/free energy。配置（用于symfony3应用程序）

server {
    listen      80;
    server_name www.free-energy.org free-energy.org;
    root /var/www/free-energy.org/web;

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

    # PROD
    location ~ ^/app\.php(/|$) {
        fastcgi_pass php-fpm-free-energy:9000;
        fastcgi_split_path_info ^(.+\.php)(/.*)$;
        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/app.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/free-energy.org_error.log;
    access_log /var/log/nginx/free-energy.org_access.log;
}

启动后，需要添加127.0。0.1自由能。org到您的/etc/hosts文件中，用于解析主机，您的应用程序将在/src/free energy上运行。org（入口点是-/src/free energy.org/web/app.php）

随着0TshEL_n1ck的回答，解决了502错误。我仍然得到'文件未找到'在浏览器和相关的错误日志在NGINX'FastCGI发送在stderr："主脚本未知"而读取响应头从上游'.

这是原来工作的配置。需要改变的关键：

• NGINX配置文件中的root指令不包含Symfony项目中所需的/public，因为前端控制器索引。php位于那里

这些要点是在使用位于https://symfony.com/doc/current/setup/web_server_configuration.html的Symfony文档的NGINX配置后发现的

这是有效的代码。

docker撰写。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配置默认值。形态：

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;
}

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

  ports:
      - "8000:9000"

或者如果它已经在您的主机上使用，您可以只在容器之间公开端口。

  expose:
      - "9000"
