Docker tutum/wordpress容器与apache2和supervisor的问题

Question

我是Docker的新手，几个月来我一直在开发一个基于图腾/ Wordpress镜像的wordpress站点。就在上周，我还在编辑wordpress网站；然而，现在当我尝试显示该网站时，什么也得不到。

自从上周它最后一次工作以来，我没有改变任何东西。我可以通过SSH连接到Ubuntu服务器。我可以看到容器正在运行，我可以连接到容器。进入容器后，我已经验证了Apache和MySQL正在运行。我可以在文件系统中导航，而Wordpress仍然在那里。

这几乎就像是无法从web访问容器一样，但我不知道从哪里开始故障排除。

更新:这似乎是supervisord和apache的一个问题。docker日志显示，由于重试次数过多，apache处于致命状态；但是，使用sudo服务apache2状态表示Apache正在运行。发出/etc/init.d/apache2stop命令后，Apache仍在运行。我就是停不下来。ps -A没有显示apache运行，只显示supervisor。我还是很困惑。

Docker Port: 80/tcp -> 0.0.0.0:80

我发现并解决了这个问题，但我不知道它是如何或为什么成为问题的，因为我已经运行这个服务器和容器几个月了。

问题是supervisord配置为运行apache2；但是，/etc/init.d/中也有一个apache2脚本

我在/etc/init.d文件夹中执行了"update-rc.d -f apache2 remove“命令，以便在启动时从初始化进程中删除此脚本。然后，我弹出了服务器，然后又恢复了业务。
