Can't start after installing using yum install docker
[root@apptest ~]# service docker start
docker: unrecognized service
If you have been stuck in the above steps, you can use the following command to install, and it will be successful. A problem made me toss for two days. I tried to turn off the firewall, turn off selinux, reinstall the system, etc. The methods that can be found on the Internet cannot be solved. If you solve it, please reply and thank me.

Is the docker daemon running on this host? If you would like to use Docker as a non-root user, you should now consider adding your user to the "docker" group with something like:sudo usermod -aG docker your-user Remember that you will have to log out and back in for this to take effect!
