Docker无法在centos7上启动：未能启动docker应用程序容器引擎

centos7通过vmware工作站播放器，和

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

首先， yum install docker-engine other_args="--selinux-enabled" >> /etc/sysconfig/docker yum install docker-engine然后， other_args="--selinux-enabled" >> /etc/sysconfig/docker当service docker start ，出现错误：

 [root@localhost Desktop]# systemctl status docker.service -l docker.service - Docker Application Container Engine Loaded: loaded (/usr/lib/systemd/system/docker.service; enabled) Active: activating (start) since 日 2015-10-25 19:49:32 PDT; 46s ago Docs: https://docs.docker.com Main PID: 14387 (docker) CGroup: /system.slice/docker.service └─14387 /usr/bin/docker daemon -H fd:// 10月 25 19:49:32 localhost.localdomain systemd[1]: Failed to start Docker Application Container Engine. 10月 25 19:49:32 localhost.localdomain systemd[1]: Unit docker.service entered failed state. 10月 25 19:49:32 localhost.localdomain systemd[1]: Starting Docker Application Container Engine... 10月 25 19:49:33 localhost.localdomain docker[14387]: time="2015-10-25T19:49:33.092885953-07:00" level=info msg="[graphdriver] using prior storage driver \"devicemapper\"" 10月 25 19:49:33 localhost.localdomain docker[14387]: time="2015-10-25T19:49:33.093697949-07:00" level=info msg="Option DefaultDriver: bridge" 10月 25 19:49:33 localhost.localdomain docker[14387]: time="2015-10-25T19:49:33.093729432-07:00" level=info msg="Option DefaultNetwork: bridge" 10月 25 19:49:33 localhost.localdomain docker[14387]: time="2015-10-25T19:49:33.108983655-07:00" level=warning msg="Running modprobe bridge nf_nat br_netfilter failed with message: modprobe: WARNING: Module br_netfilter not found.\n, error: exit status 1"
