centos 6.9安装docker操作步骤

本人是通过在自己电脑安装vmware 后，再进行安装centos 6.9 服务器

vmware可以通过在官网下载版本包进行安装： 

https://my.vmware.com/en/web/vmware/free#desktop_end_user_computing/vmware_workstation_player/14_0

linux 的IOS镜像文件是通过阿里开源镜像网站获取： http://mirrors.aliyun.com/， 同时也可以通过网易开源镜像网站获取http://mirrors.163.com/

开始进行docker安装

 [root@localhost docker]# yum -y install docker-io
Loaded plugins: fastestmirror, refresh-packagekit, security
Setting up Install Process
Loading mirror speeds from cached hostfile
 * base: mirrors.zju.edu.cn
 * extras: mirrors.nju.edu.cn
 * updates: mirrors.nju.edu.cn
No package docker-io available.
Error: Nothing to do

执行yum -y install docker-io 发现报错，提示找不到可用安装包， 需要更新第三方软件库

[root@localhost docker]# sudo yum install epel-release
Loaded plugins: fastestmirror, refresh-packagekit, security
Setting up Install Process
Loading mirror speeds from cached hostfile
 * base: mirrors.zju.edu.cn
 * extras: mirrors.nju.edu.cn
 * updates: mirrors.nju.edu.cn
Resolving Dependencies
--> Running transaction check

更新后从新执行yum 安装即可

[root@localhost docker]# yum -y install docker-io
Loaded plugins: fastestmirror, refresh-packagekit, security

启动docker进程

[root@localhost docker]# service docker start 
Starting cgconfig service:                                 [  OK  ]
Starting docker:                                   [  OK  ]
[root@localhost docker]# 

验证是否安装成功，在容器中执行一个测试镜像

[root@localhost docker]# docker run hello-wordl
Unable to find image 'hello-wordl:latest' locally
^C[root@localhost docker]# docker run hello-world
