请教下centos7启动docker异常?
启动docker
service docker start
Starting docker (via systemctl):Job for docker.service failed. See 'systemctl status docker.service' and 'journalctl -xn' for details.
按提示敲systemctl status docker.service
systemctl status docker.service

可能和Selinux冲突，禁用Selinux一下试试。

记录下解决方法，感谢@刘钧 。
查看SELinux状态：
1、/usr/sbin/sestatus -v <span style="font-size:16px">如果SELinux status参数为enabled即为开启状态</span>
SELinux status: enabled
2、getenforce <span style="font-size:16px">也可以用这个命令检查</span>
关闭SELinux：
1、临时关闭（不用重启机器）：
setenforce 0 <span style="font-size:16px">设置SELinux 成为permissive模式</span>
<span style="font-size:16px">setenforce 1 设置SELinux 成为enforcing模式</span>
2、修改配置文件需要重启机器：
修改/etc/selinux/config 文件
将SELINUX=enforcing改为SELINUX=disabled
重启机器即可

虽然关闭了selinux，但是貌似执行docker 还是会出现下面错误：
docker images
Get http:///var/run/docker.sock/v1.20/images/json: dial unix /var/run/docker.sock: no such file or directory.* Are you trying to connect to a TLS-enabled daemon without TLS?
* Is your docker daemon up and running?
重启docker服务，就正常了。
