我正在尝试使用Apache（httpd）和PHP 5.3.3构建Docker镜像。该图片基于我制作的CentOS 6 && Supervisord。到目前为止，一切正常，＃34;罚款＆＃34; （这意味着在构建过程中没有问题）但我遇到了Apache和Supervisord的一些问题。为什么？因为我认为基于reynierpm/centos6-supervisord的图像已经启动Apache，然后Supervisord正在尝试做同样的事情。这是我使用docker-compose up启动堆栈时所获得的日志：

我创建了一个gist，其中包含Dockerfile和Supervisord读取的httpd.conf文件，我在这里做错了什么？
