详解使用 Docker 构建 LNMP 环境

docker-compose.yml

   - 8080:80

   - php
  # 同 php 一起共享 ./apps 目录
  volumes_from:
   - php
  # 创建一个数据卷，由 ./images/nginx/config => /etc/nginx/conf.d

 # MySQL 5.7: https://hub.docker.com/_/mysql/
 database: 
  image: mysql:5.7
  # 配置一些环境变量，具体的环境变量细节可以访问上面的网址查看
  environment:

  volumes:
