我按照此博客“https://blogs.oracle.com/hlsu/install-docker-on-oracle-linux-7”中的说明在我的Oracle Linux 7服务器中安装了docker引擎。
这是我yum install docker-engine的日志：

它似乎已正确安装，但下一步我，e。启动docker会给我这个错误：

有人可以解释为什么会这样吗？ 非常感谢！

请注意错误消息
运行docker不支持您的Linux内核版本3.8.13-55.1.6.el7uek.x86_64。请将您的内核升级到3.10.0或更高版本。
您需要内核3.10+才能安装docker
