1.创建项目目录， mkdir -p sh04/ 这里将其命名为 php-nginx-supervisord

2.在该项目下创建 nginx 子目录，准备 nginx 服务的配置文件，这里包括 nginx.conf 和 conf.d/site.conf  

3.在该目录下创建 supervisord 子目录，再创建一个下级目录 conf.d ，在其准备 supervisord 的配置文件 supervisord.conf 

4.在项目目录下编写 Dockerfile 

5.在项目目录下基于 Dockerfile 构建镜像

6.在项目目录下基于构建的镜像重启容器

7.实际测试 Web 服务

！！！代码及其解决报错完整如下：
