Failed to start Docker Application Container Engine. yum安装docker启动报错

yum安装docker启动报错
[root@bogon ~]# systemctl restart docker
Job for docker.service failed because the control process exited with error code. See “systemctl status docker.service” and “journalctl -xe” for details.

（1）检查防火墙是否关闭
setenforce 0
systemctl stop firewalld.service
（2）编辑docker配置文件
提示用systemctl status -l docker 看报错

意思是说：此linux的内核中的SELinux不支持 overlay2 graph driver ，解决方法有两个，要么启动一个新内核，要么就在docker里禁用selinux，–selinux-enabled=false 继续根据提示走修改为false

vi /etc/sysconfig/docker
将selinux改为false
systemctl start docker.service
重新启动成功
