先上服务器环境信息：

卸载的原因：

   宿主机过段时间就磁盘100%了，导致continart异常退出，后来找了很多解决方案，才发现是安装docker的时候有个配置文件错误（正常的应该是|Storage Driver: overlay2）。

上干货：

①卸载

1 yum remove docker \ 2                   docker-client \ 3                   docker-client-latest \ 4                   docker-common \ 5                   docker-latest \ 6                   docker-latest-logrotate \ 7                   docker-logrotate \ 8                   docker-selinux \ 9                   docker-engine-selinux \10                   docker-engine11 12 rm -rf /etc/systemd/system/docker.service.d13 14 rm -rf /var/lib/docker15 16 rm -rf /var/run/docker

②安装
