`centos-extras` 仓库需要被启用。这个仓库在默认情况下是启用的,但是可能因为其他的原因被关闭了,请参考 [重新启用 centos-extras 仓库](https://wiki.centos.org/AdditionalResources/Repositories) 页面中的内容。

It's OK if `yum` reports that none of these packages are installed.
如果在使用 `yum` 的时候,提示没有任何上面的包被安装的话,也没有关系。你可以跳过这个卸载的过程。reports that none of these packages are installed.
The contents of `/var/lib/docker/`, including images, containers, volumes, and
networks, are preserved. The Docker Engine package is now called `docker-ce`.
路径 `/var/lib/docker/` 下的内容包含有 镜像(images),容器(containers),卷(volumes),网络(networks)这些内容。这些内容是 Docker 容器运行需要的必要配置。
Docker 引擎(Docker Engine)的包,当前被修改称为 `docker-ce`。
