CentOS7安装docker
1、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 。
查看你当前的内核版本
[root@localhost ~]# uname -r
3.10.0-862.el7.x86_64
2、yum包更新到最新
[root@localhost ~]# yum update
Loaded plugins: fastestmirror
Determining fastest mirrors
* base: mirrors.aliyun.com
* extras: mirrors.aliyun.com
* updates: mirrors.aliyun.com
。。。等等各种日志
3、卸载原来的docker
[root@localhost ~]# yum remove docker docker-common docker-selinux docker-engine
Loaded plugins: fastestmirror
No Match for argument: docker
No Match for argument: docker-common
No Match for argument: docker-selinux
No Match for argument: docker-engine
No Packages marked for removal
4、安装需要的软件包， yum-util 提供yum-config-manager功能，另外两个是devicemapper驱动依赖的
[root@localhost ~]# yum install -y yum-utils device-mapper-persistent-data lvm2
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* base: mirrors.aliyun.com
* extras: mirrors.aliyun.com
* updates: mirrors.aliyun.com
Package device-mapper-persistent-data-0.7.3-3.el7.x86_64 already installed and latest version
Package 7:lvm2-2.02.180-10.el7_6.8.x86_64 already installed and latest version

5、设置yum源
[root@localhost ~]# yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
Loaded plugins: fastestmirror
adding repo from: https://download.docker.com/linux/centos/docker-ce.repo
grabbing file https://download.docker.com/linux/centos/docker-ce.repo to /etc/yum.repos.d/docker-ce.repo
repo saved to /etc/yum.repos.d/docker-ce.repo
6、可以查看一下所有仓库中所有docker版本，并选择特定版本安装
[root@localhost ~]# yum list docker-ce --showduplicates | sort -r
