**卸载旧版本**

如果以前安装过 Docker ，请卸载它们以及相关的依赖项。

sudo yum remove docker \
                      docker-client \
                      docker-client-latest \
                      docker-common \
                      docker-latest \
                      docker-latest-logrotate \
                      docker-logrotate \
                      docker-selinux \
                      docker-engine-selinux \
                      docker-engine

**使用阿里云源进行安装（注意：安装Docker Compose必须先安装Docker）**

sudo yum install -y yum-utils device-mapper-persistent-data lvm2
    sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
    sudo yum install docker-ce
    # 启动
    sudo systemctl start docker
    # 开机启动
    sudo systemctl enable docker

**Docker Compose 安装**

sudo curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
    sudo chmod +x /usr/local/bin/docker-compose
    sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

**测试是否成功**

docker-compose --version
    # docker-compose version 1.24.1, build 4667896b

**为Docker配置阿里云加速**

*  进入阿里云的容器镜像服务

快速链接： [容器镜像服务][Link 1]

可以免费获得一个加速器地址

*  配置镜像加速器

sudo mkdir -p /etc/docker
    sudo tee /etc/docker/daemon.json <<-'EOF'
    {
      "registry-mirrors": ["https://aip0wjyl.mirror.aliyuncs.com"]
    }
    EOF
    sudo systemctl daemon-reload
    sudo systemctl restart docker
