Docker无法启动centos7：无法启动docker应用程序容器引擎

Question

centos7通过vmware工作站播放器，

[root@localhost Desktop]# uname -r
3.10.0-229.14.1.el7.x86_64

首先，yum install docker-engine 然后，other_args="--selinux-enabled" >> /etc/sysconfig/docker 当service docker start时，我收到错误：

[root@localhost Desktop]# systemctl status docker.service -l
docker.service - Docker Application Container Engine
