创建yum源
[root@bogon ~]#
[root@bogon ~]# yum-config-manager --add-repo https:///linux/centos/docker-ce.repo
Loaded plugins: fastestmirror, langpacks
adding repo from: https:///linux/centos/docker-ce.repo
grabbing file https:///linux/centos/docker-ce.repo to /etc/yum.repos.d/docker-ce.repo
Could not fetch/save url https:///linux/centos/docker-ce.repo to file /etc/yum.repos.d/docker-ce.repo: [Errno 14] curl#7 - "Failed connect to :443; Operation now in progress"
[root@bogon ~]#
[root@bogon ~]#
链接无法解析改为使用阿里的yum源，操作如下：
[root@bogon ~]# yum-config-manager --add-repo /docker-ce/linux/centos/docker-ce.repo
Loaded plugins: fastestmirror, langpacks
adding repo from: /docker-ce/linux/centos/docker-ce.repo
grabbing file /docker-ce/linux/centos/docker-ce.repo to /etc/yum.repos.d/docker-ce.repo
repo saved to /etc/yum.repos.d/docker-ce.repo
安装最新的docker
[root@bogon ~]#
[root@bogon ~]# yum install docker-ce

此处发下yum被进程号为9034占用，直接kill
[root@bogon ~]# ps aux | grep yum

[root@bogon ~]# kill -9 9034
[root@bogon ~]# ps aux | grep yum
