centos 6.9安装docker操作步骤
docker 安装测试
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

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
