我是 Docker 新手，几个月来我一直在基于 tutum/wordpress 图像开发一个 Wordpress 网站。就在上周，我编辑了 wordpress 网站；但是，现在当我尝试显示该网站时，我什么也得不到。

自上周上次工作以来，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，并且可以附加到容器。进入容器后，我已验证 Apache 和 MySQL 正在运行。我可以浏览文件系统并且 Wordpress 仍然存在。

几乎就像无法从 Web 访问容器一样，但我不知道从哪里开始进行故障排除。

更新：supervisord 和 apache 似乎有问题。docker 日志说 apache 由于重试次数过多而处于致命状态；但是，使用 sudo service apache2 status 表示 Apache 正在运行。发出 /etc/init.d/apache2 停止命令后，Apache 仍在运行。我不能让它停下来。ps -A 不显示 apache 正在运行，只有主管。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被配置为运行apache2；但是，/etc/init.d/ 中还有一个 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 init 进程中删除此脚本。然后我反弹了服务器并恢复了业务。
