centOS7安装完docker之后无法启动问题

centOS直接用yum命令安装完docker后,启动报错

Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

用systemctl status docker.service命令 查看日志,有如下错误,其中有一条 SELinux is not supported with the overlay2 graph driver on this kernel. Either boot into a newer kernel or disable selinux in docker (--selinux-enabled=false)  
 

根据错误日志得知,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
重新编辑docker配置文件:
# vim /etc/sysconfig/docker
