Ubuntu on Docker Mount Trouble Shooting

(My environment is Mint7.1, equivalent to Ubuntu14.04)

1, first, according to the installation instructions on the docker.com to install Docker, here is not repeated, reference:

https://docs.docker.com/installation/ubuntulinux/

2, perform

$ docker Version

You may encounter the following error:
FATA[0000] Get http:///var/run/docker.sock/v1.17/version:dial Unix/var/run/docker.sock:permission denied. is trying to connect to a tls-enabled daemon without TLS?

This may be due to the fact that the current user has not been added to the Docker group to perform

$ sudo gpasswd-a ${user} docker

Restart the machine to check if the current user is in the Docker group

$ groups

Perform a command restart service

$ sudo service Docker.io restart

3, execute again

$ docker Version

You may encounter the following error:
FATA[0000] Cannot connect to the Docker daemon. Is ' docker-d ' running on this host?

This may be caused by the absence of the installation of AppArmor, which performs

Apt-get Install AppArmor

Restart your computer to perform:

$ PS-EF | grep Docker

Root 4577 1 0 21:44? 00:00:00/usr/bin/docker-d

Alex 4608 2574 0 21:45 pts/0 00:00:00 grep--color=auto Docker

The above output indicates that the installation was successful.
