docker-compose exec nginx bash            登录到nginx容器中

docker-compose down                              删除所有nginx容器,镜像

docker-compose ps                                   显示所有容器

docker-compose restart nginx                   重新启动nginx容器

docker-compose run --no-deps --rm php-fpm php -v  在php-fpm中不启动关联容器，并容器执行php -v 执行完成后删除容器
