centos7 启动docker失败--selinux-enabled=false

centos7,执行完安装命令： yum install docker

执行启动命令： systemctl   start docker  ,报下面错误：

Error starting daemon: 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)

重新编辑docker配置文件：

vi /etc/sysconfig/docker

# /etc/sysconfig/docker

# Modify these options if you want to change the way the docker daemon runs

OPTIONS='--selinux-enabled=false  --log-driver=journald --signature-verification=false'
if [ -z "${DOCKER_CERT_PATH}" ]; then
    DOCKER_CERT_PATH=/etc/docker
fi

:wq 

systemctl  restart  docker
