docker安装后启动不了

docker 敲入代码启动不了，

[root@localhost ~]# sudo service docker start
Redirecting to /bin/systemctl start  docker.service
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

  出现了这样的报错，我们需要修改

vi /etc/sysconfig/docker

找到OPTIONS='--selinux-enabled --log-driver=journald --signature-verification=false'

找到这一行改为OPTIONS='--selinux-enabled=false --log-driver=journald --signature-verification=false'

也就是说在'--selinux-enabled后面加了=false
