nginx 指定访问端口(vue history方式编译)

### docker-compose 指定映射端口
services:
  nginx:
      image: nginx
      restart: always
      container_name: project_name
      volumes:
      - /d/usr/project_name/nginx/www/:/usr/share/nginx/html/         # 默认index页面
      - /d/usr/project_name/nginx/conf/nginx.conf:/etc/nginx/nginx.conf
      ports:
        - 8080:8080
  ...其他不变

### nginx.conf修改监听端口与配置
