What should I do if centos docker fails to start?

centos7 solution to the failure to start docker:

The control terminal uses yum install docker to install docker and then fails to start docker, and the following message appears:

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

I was confused at that time, I followed the prompt systemctl status docker.service and then the following information appeared on the control end:

Me I found that this seems to be due to docker not supporting the image kernel driver: SELinux does not support the OrthALA2 graphics driver on this kernel

Re-edit the docker configuration file:

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

Finally recompile: systemctl restart docker successful!
