yum安装docker报错：Job for docker.service failed because the control process exited with error code

一. 检查Linux内核版本，CenterOS7安装docker要求内核版本在3.10以上：uname  -r

二. 使用yum命令安装：yum install docker

三. 启动Docker：systemctl start docker

有时候会看到如下的报错：

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

执行：systemctl status docker.service  查看详细的错误信息

具体原因是：是由于docker不支持图像内核驱动，SELinux不支持这个内核上的OrthALA2图形驱动程序

解决方式：修改docker配置文件：vim  /etc/sysconfig/docker

 

把OPTIONS一行改为：OPTIONS='--selinux-enabled=false --log-driver=journald --signature-verification=false'

再启动：systemctl start docker 就可以了
