1，docker-ce安装：
yum remove dockerdocker-common docker-selinuxdocker-engine
yum install -y yum-utils device-mapper-persistent-data lvm2
sudo yum-config-manager \
--add-repo \
https://mirrors.ustc.edu.cn/docker-ce/linux/centos/docker-ce.repo
sudo yum makecache fast
sudo yum install docker-ce
yum list docker-ce --showduplicates | sort -r
sudo yum install <FULLY-QUALIFIED-PACKAGE-NAME> example:docker-ce-17.06.1.ce
sudo systemctl enable docker
sudo chkconfig docker on
sudo systemctl start docker
docker version
docker run hello-world

2，配置镜像加速器:
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://urh00mp2.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

2，卸载docker-ce
sudo yum remove docker-ce
sudo rm -rf /var/lib/docker

3，建立docker用户组：
sudo group add docker
sudo user mod -aGdockerdocker
