docker - 在centos7上安装docker后，无法启动docker ."Job for docker.service failed."

Question

执行后 yum install docker在 centos7 , 我想通过执行 service docker start 来启动 docker ，然后我可以看到错误:

Redirecting to /bin/systemctl start docker.service Job for docker.service failed. See 'systemctl status docker.service' and 'journalctl -xn' for details.

然后我执行 systemctl status docker.service -l ，那么错误是:

docker.service - Docker Application Container Engine
   Loaded: loaded (/usr/lib/systemd/system/docker.service; disabled)
   Active: failed (Result: exit-code) since Sun 2015-03-15 03:49:49 EDT; 12min ago

此错误通常是由于缺少 device-mapper-event-libs 包而发生的。

# yum install device-mapper-event-libs
