$sudo usermod -aG docker $USER

配置docker服务 

$sudo wget https://github.com/docker/docker/raw/v1.11.2/contrib/init/systemd/docker.service -O /usr/lib/systemd/system/docker.service 
$sudo wget https://github.com/docker/docker/raw/v1.11.2/contrib/init/systemd/docker.socket -O /usr/lib/systemd/system/docker.socket 

$sudo systemctl daemon-reload 
$sudo systemctl enable docker.service
