## 准备工作 ##

1.centos系统  
2.yum

## 开始安装 ##

### 更新yum ###

[root@localhost ~]# yum update

中途会有一个或多个确认的提示，输入y（yes首字母）继续。

### 查找docker ###

待更新完毕之后，查看docker的列表

[root@localhost ~]# yum list docker

查询的结果如下：

[root@localhost ~]# yum list docker 
    已加载插件：fastestmirror, langpacks
    Loading mirror speeds from cached hostfile
     * base: mirror.jdcloud.com
     * extras: mirrors.aliyun.com
     * updates: mirror.jdcloud.com
    可安装的软件包
    docker.x86_64                                                       2:1.13.1-103.git7f2769b.el7.centos                                                        extras

### 安装docker ###

我们根据docker列表选择需要安装的软件包docker.x86\_64进行安装

[root@localhost ~]# yum install docker.x86_64

安装结果如下：

已安装:
      docker.x86_64 2:1.13.1-103.git7f2769b.el7.centos                                                                                                                  
    
    作为依赖被安装:

    Hello from Docker!
    This message shows that your installation appears to be working correctly.
    
    To generate this message, Docker took the following steps:
     1. The Docker client contacted the Docker daemon.
     2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
        (amd64)
     3. The Docker daemon created a new container from that image which runs the
        executable that produces the output you are currently reading.
     4. The Docker daemon streamed that output to the Docker client, which sent it
        to your terminal.
    
    To try something more ambitious, you can run an Ubuntu container with:
     $ docker run -it ubuntu bash
