使用 Docker Compose 和 WordPress 镜像设置 Xdebug

Question

我正在尝试使用 docker-compose 设置 Xdebug。我使用的是 PhpStorm IDE，我使用的 Docker 映像安装了 PHP 7.2。我正在尝试在此 WordPress 图像的上下文中执行此操作。这是我当前的 docker-compose.yml 文件：

    version: '3'

    services:
   db:
     image: mysql:5.7
     ports: 
       - "3306:3306"
     volumes:
       - db_data:/var/lib/mysql
     restart: always
     environment:
       MYSQL_ROOT_PASSWORD: somewordpress
       MYSQL_DATABASE: wordpress
       MYSQL_USER: wordpress
       MYSQL_PASSWORD: wordpress

   web-build-scripts:
     build: .
     depends_on:
       - db
     ports:
       - "8028:80"
       - "8029:8029"

     volumes:
       - ./themes/XXXXX:/var/www/html/wp-content/themes/XXXX
       - ./plugins/XXXX:/var/www/html/wp-content/plugins/XXXXX
       - ./plugins/XXXXX:/var/www/html/wp-content/plugins/XXXXX
       - ./plugins/XXXXX:/var/www/html/wp-content/plugins/XXXXX
       - ./plugins/XXXXX:/var/www/html/wp-content/plugins/XXXXX
       - ./plugins/XXXXX:/var/www/html/wp-content/plugins/XXXXX
       - ./plugins/XXXXX:/var/www/html/wp-content/plugins/XXXXX
       - ./plugins/XXXXX:/var/www/html/wp-content/plugins/XXXXX
       - ./plugins/XXXXX:/var/www/html/wp-content/plugins/XXXXX


     restart: always
     environment:
       WORDPRESS_DB_HOST: db:3306
       WORDPRESS_DB_USER: wordpress
       WORDPRESS_DB_PASSWORD: wordpress
       VIRTUAL_HOST: leasepilot.local

volumes:
    db_data:

然后我标记为 web-build-scripts（当然是构建的）的 Dockerfile 看起来像这样：

FROM wordpress:latest

WORKDIR /var/www/html
RUN pecl install xdebug-2.6.0 \
    && docker-php-ext-enable xdebug \
    && apt-get update \
    && apt-get install nano \
    && export TERM=xterm

COPY Search-Replace-DB/ ./wp-content/Search-Replace-DB/
COPY uploads/ ./wp-content/uploads/
COPY ./docker-config/xdebug.ini ../../../usr/local/etc/php/conf.d/xdebug.ini

我的本地 docker-config 目录中的 xdebug.ini 文件如下所示：

zend_extension=xdebug.so
xdebug.default_enable=1
xdebug.remote_autostart=1
xdebug.remote_connect_back=0
xdebug.remote_port=9001
xdebug.remote_enable=1
xdebug.idekey=PHPSTR
xdebug.remote_host = docker.for.mac.internal

在 PHPStorm 中，我设置了如下调试设置： 我已经像这样设置了服务器映射：

我还像在 xdebug.ini 文件中一样将调试端口设置为 9001：

当我运行命令 php -ini | grep xdebug 我的输出如下：

root@a96543427809:/var/www/html# php -ini | grep xdebug
Cannot load Xdebug - it was already loaded

我已经浏览了几个教程，但无法弄清楚这一点。任何人都有任何可以帮助我的见解？

我会怎么做

• 首先，您正在使用，wordpress:latest因此您必须找到您的 wordpress 图像正在运行的 php 版本。
• 然后检查是否xdebug安装在容器中。很可能不是！
• 为开发创建一个Dockerfilewithxdebug安装，不要将它用于生产，它会降低你的性能。
• 从中构建您的 wordpress图像Dockerfile。
• 您可能需要xdebug.ini使用远程主机详细信息创建文件，我正在使用 phpstrom 这就是我的xdebug.ini样子。我将此文件保存在我的主机中并使用volumes.

zend_extension=xdebug.so
xdebug.remote_enable=1
xdebug.remote_handler=dbgp
xdebug.remote_port=10000 # dont use 9000 its usually used by the php-fpm
xdebug.remote_autostart=1
xdebug.remote_connect_back=0
xdebug.idekey=PHPSTRM
xdebug.remote_host=host-ip-here

这就是我的 docker-compose 文件的样子

version: '2'
services:
    my-service:
        build:
          context: ./dev
          dockerfile: Dockerfile
        ports:
            - "8080:80"
        restart: always
        environment:
            - RUNTIME_ENVIRONMENT=local
        working_dir: /src
        volumes:
            - ./src:/src
            - ./php-ini-overrides-dev.ini/xdebug.ini:/etc/php/7.1/mods-available/xdebug.ini

• 然后详细配置phpstorm远程调试xdebug.ini。
• 要确保加载了 xdebug 配置，请登录到容器并运行 php -ini | grep xdebug
• 这是获得xdebug作品的一种方式。
• 如果它不起作用启用 xdebug 日志，添加xdebug.remote_log=/log_path/xdebug.log到 xdebug.ini 将有助于诊断问题。
• 如果您在设置 phpstorm 远程调试方面还需要帮助，请告诉我。其实里面有很多资源。
