总结

通过在AWS的EC2上使用Docker Compose，我已经创建了WordPress、MySQL和phpMyAdmin的环境，为了方便以后查看，我将其记录下来。省略了Docker的安装步骤等。
由于还未写出EC2实例连接的步骤，我会在另外的帖子中发布。

我在GitHub中搜索了”docker wordpress”，并克隆了星星数较多的存储库。

在进行环境配置时，我将编辑以下的”docker-compose.yml”文件和”.env”文件，然后进行执行。最终要执行的文件在底部附有说明。

version: '3'

services:
  wp:
    image: wordpress:latest # https://hub.docker.com/_/wordpress/
    ports:
      - ${IP}:80:80 # change ip if required
    volumes:
      - ./config/php.conf.ini:/usr/local/etc/php/conf.d/conf.ini
      - ./wp-app:/var/www/html # Full wordpress project
      #- ./plugin-name/trunk/:/var/www/html/wp-content/plugins/plugin-name # Plugin development
      #- ./theme-name/trunk/:/var/www/html/wp-content/themes/theme-name # Theme development
    environment:
      WORDPRESS_DB_HOST: db
      WORDPRESS_DB_NAME: "${DB_NAME}"
      WORDPRESS_DB_USER: root
      WORDPRESS_DB_PASSWORD: "${DB_ROOT_PASSWORD}"
    depends_on:
      - db
    links:
      - db

  wpcli:
    image: wordpress:cli
    volumes:
      - ./config/php.conf.ini:/usr/local/etc/php/conf.d/conf.ini
      - ./wp-app:/var/www/html
    depends_on:
      - db
      - wp

  pma:
    image: phpmyadmin/phpmyadmin
    environment:
      # https://docs.phpmyadmin.net/en/latest/setup.html#docker-environment-variables
      PMA_HOST: db
      PMA_PORT: 3306
      MYSQL_ROOT_PASSWORD: "${DB_ROOT_PASSWORD}"
    ports:
      - ${IP}:8080:80
    links:
      - db:db

  db:
    image: mysql:latest # https://hub.docker.com/_/mysql/ - or mariadb https://hub.docker.com/_/mariadb
    ports:
      - ${IP}:3306:3306 # change ip if required
    command: [
        '--default_authentication_plugin=mysql_native_password',
        '--character-set-server=utf8mb4',
        '--collation-server=utf8mb4_unicode_ci'
    ]
    volumes:
      - ./wp-data:/docker-entrypoint-initdb.d
      - db_data:/var/lib/mysql
    environment:
      MYSQL_DATABASE: "${DB_NAME}"
      MYSQL_ROOT_PASSWORD: "${DB_ROOT_PASSWORD}"

volumes:
  db_data:

IP=127.0.0.1
DB_ROOT_PASSWORD=password
DB_NAME=wordpress

步骤

克隆存储库

首先，通过SSH连接到EC2实例，并克隆存储库。

git clone  https://github.com/nezhar/wordpress-docker-compose.git

编辑前的文件

确认”wordpress-docker-compose”文件夹已经创建，然后编辑其中的”docker-compose.yml”文件。如果不进行编辑并直接运行，将默认设置回环地址”IP=127.0.0.1″，这样无法访问。因此，需要删除”${IP}:”。要删除的位置分别在”web”、”pma”和”db”服务的三个地方。

#変更前
ports:
      - ${IP}:80:80
      　　︙
      - ${IP}:8080:80
      　　︙
      - ${IP}:3306:3306

#変更後
ports:
      - 80:80
      　　︙
      - 8080:80
      　　︙
      - 3306:3306

另外，为了省略phpMyAdmin的登录输入，我们可以添加PMA_USER和PMA_PASSWORD。

PMA_USER: root
PMA_PASSWORD: "${DB_ROOT_PASSWORD}"

我会在“PMA”和“DB”服务中添加以下内容。

MYSQL_USER: "${DB_USER}"
MYSQL_PASSWORD: "${DB_PASSWORD}"

将以下内容添加到 “.env” 文件中。

DB_USER=wordpress
DB_PASSWORD=wordpress

编辑后的文件 de

以下是編輯完成的 “docker-compose.yml” 文件和 “.env” 文件。

      PMA_USER: root #add
      PMA_PASSWORD: "${DB_ROOT_PASSWORD}" #add
      MYSQL_ROOT_PASSWORD: "${DB_ROOT_PASSWORD}"
      MYSQL_USER: "${DB_USER}" #add
      MYSQL_PASSWORD: "${DB_PASSWORD}" #add
    ports:

        '--character-set-server=utf8mb4',
        '--collation-server=utf8mb4_unicode_ci'
    ]
    volumes:
      - ./wp-data:/docker-entrypoint-initdb.d
      - db_data:/var/lib/mysql
    environment:
      MYSQL_DATABASE: "${DB_NAME}"
      MYSQL_ROOT_PASSWORD: "${DB_ROOT_PASSWORD}"
      MYSQL_USER: "${DB_USER}" #add
      MYSQL_PASSWORD: "${DB_PASSWORD}" #add
volumes:
  db_data:

IP=127.0.0.1
DB_ROOT_PASSWORD=password
DB_NAME=wordpress
DB_USER=wordpress
DB_PASSWORD=wordpress

启动容器

启动容器。如果在执行下面的命令后重新编辑文件，请再次执行下面的命令。

docker-compose up -d

开始使用WordPress

请访问公共DNS。如果一切顺利，您应该能看到WordPress的界面。
（例如）http://ec2-･･････.ap-northeast-1.compute.amazonaws.com/

另外，请在URL后面加上”:8080″，访问phpMyAdmin，示例如下：http://ec2-･･････.ap-northeast-1.compute.amazonaws.com:8080

请提供更多的上下文信息以便为您提供准确的翻译。
