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-engine 11 12 rm -rf /etc/systemd/system/docker.service.d 13 14 rm -rf /var/lib/docker 15 16 rm -rf /var/run/docker
②安装
