为快速安装部署，目前已提供docker一键安装脚本！

1、检查系统内核
Docker 要求 CentOS 系统的内核版本高于 3.10 ，查看本页面的前提条件来验证你的CentOS 版本是否支持 Docker 。

通过 uname -r 命令查看你当前的内核版本。

[xcbeyond@docker ~]$ uname -r
3.10.0-327.10.1.el7.x86_64

2、安装Docker
安装过程及其坎坷，出现了各种问题，并进行记录整个过程，与大家进行分享。2.1 节记录安装过程中出现的各种问题，2.2节整理的是安装成功过程，作为正常安装步骤。

2.1 安装失败
（1）Docker 软件包和依赖包已经包含在默认的 CentOS-Extras 软件源里。执行命令yum install docker

安装过程如下：

[xcbeyond@docker etc]$ sudo yum install docker

It was impossible to connect to the CentOS servers.
This could mean a connectivity issue in your environment, such as the requirement to configure a proxy,
or a transparent proxy that tampers with TLS security, or an incorrect system clock.
