基于 Ubuntu 基础镜像构建 MySQL 的 Dockerfile：

FROM phusion/baseimage:master

ENV HOME /root
ENV MYSQL_USERNAME root
ENV MYSQL_PASSWORD 123456
ENV MYSQL_DB_NAME my_db

CMD ["/sbin/my_init"]
RUN apt-get update && \
    apt-get -y install mysql-server
EXPOSE 3306
# 在基础镜像 /etc/my_init.d/ 中的脚本会在容器启动时执行
COPY ./my_init.d/start_mysql.sh /etc/my_init.d/start_mysql.sh
RUN apt-get clean && rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*

使用 Ubuntu 基础镜像构建 Nginx，PHP，MySQL 镜像，并使用 Docker-Compose 构建一个 WordPress 站点的 docker-compose.yml：

version: '3'
services:
  mysql:
    build:
      context: ./MySQL
      dockerfile: Dockerfile
    environment:
      MYSQL_DB_NAME: wordpress
      MYSQL_USERNAME: root
      MYSQL_PASSWORD: 123456
    ports:
      - "3306:3306"
    volumes:
      - ./MySQL/conf/my.cnf:/etc/mysql/my.cnf:ro # 挂载配置文件，允许简单密码。
  php:
    build:
      context: ./PHP
      dockerfile: Dockerfile
    ports:
      - "9000:9000"
    volumes:
      - ~/playground/wordpress:/var/www/html # 挂载 WordPress 静态文件
      - ./PHP/conf/www.conf:/etc/php/7.0/fpm/pool.d/www.conf:ro # 挂载 php-fpm 配置文件。
  nginx:
    build:
      context: ./Nginx
      dockerfile: Dockerfile
    ports:
      - "80:80"
    volumes:
      - ./Nginx/conf/nginx.conf:/etc/nginx/nginx.conf:ro # 挂载 Nginx 配置文件。
    volumes_from:
      - php # 共享 PHP 的数据卷。
    depends_on:
      - php
