这个问题！

[root@test~]#
使用yuminstalldocker安装完后启动不了
[root@apptest~]#servicedockerstart Redirectingto/bin/systemctlstartdocker.service
一直停留在以上步骤
可以使用以下命令来安装，即可成功。
一个问题让我折腾了两天，试过关闭防火墙，关闭selinux，重装系统，等等网上能查到的方法都解决不了。
如果大家解决了，回复感谢下我吧。
[root@apptest~]#yumremovedocker [root@apptest~]#yumremovedocker-selinux [root@testyum.repos.d]#vi/etc/yum.repos.d/docker.repo [dockerrepo] name=DockerRepository baseurl=https://yum.dockerproject.org/repo/main/centos/$releasever/ enabled=1 gpgcheck=1 gpgkey=https://yum.dockerproject.org/gpg [root@testyum.repos.d]#yuminstalldocker-engine
已安装:
docker-engine.x86_640:1.10.2-1.el7.centos
作为依赖被安装:
docker-engine-selinux.noarch0:1.10.2-1.el7.centos

或者使用以下方法
