centos7版本部署docker

yum install epel-release -y
         yum install -y yum-utils   device-mapper-persistent-data   lvm2
         yum-config-manager     --add-repo     https://download.docker.com/linux/centos/docker-ce.repo
         yum-config-manager --enable docker-ce-nightly

         yum-config-manager --disable docker-ce-nightly
         yum install docker-ce docker-ce-cli containerd.io

配置镜像加速，选择阿里云的源

#本身注册一个阿里云帐号，而后选择ECS中的镜像加速服务，就能够出现一个加速地址，将加速地址配到json文件中

#也就是如下步骤

mkdir /etc/docker -p
    vim /etc/docker/daemon.json
    {
    "registry-mirrors": ["https://g80gj7jy.mirror.aliyuncs.com"]
    }
    systemctl daemon-reload
    systemctl restart docker

检测docker进程测试

ps -ef|grep docker
        docker run hello-world
