<strong>Docker简介</strong></p>
<p>
Docker 是一个开源的应用容器引擎，让开发者可以打包他们的应用以及依赖包到一个可移植的容器中，然后发布到任何流行的 Linux 机器上，也可以实现虚拟化。容器是完全使用沙箱机制，相互之间不会有任何接口。Docker 使用客户端-服务器 (C/S) 架构模式，使用远程API来管理和创建Docker容器。Docker 容器通过 Docker 镜像来创建。容器与镜像的关系类似于面向对象编程中的对象与类。官网地址：http://www.docker.com/</p>

<strong>Docker安装</strong></p>
<p>
系统要求CentOS 7.X 以上版本，内核至少3.10，64-bit</p>
<p>
1、uname –r 检查内核版本</p>
<p>
2、vi /etc/profile 修改代理设置（如果需要设置代理。内容如下，**为密码，密码要避免含有@符号）</p>
