     寻找合适的docker Yum源木配置文件

    下面是清华大学Yum源的网址：

     https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/centos/

     1,下载想要的Yum源文件，/etc/yum.repos.d

   

wget https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/centos/docker-ce.repo

 

    2,修改yum的默认下载地址  vim打开 docker-ce.repo 修改下载连接，把download.docker.com 替换成清华大学的地址 mirrors.tuna.tsinghua.edu.cn/docker-ce

 vim /etc/yum.repos.d/docker-ce.repo

 

   3，查看更新Yum源缓存：

 

yum repolist 

    4， Yum安装安装 Docker-CE，一般个人用建议安装CE版的

       

Yum install –y  docker-ce

     5，Docker镜像下载加速，为的是以后下载各种Docker镜像速度更快

mkdir –p /etc/docker
vim /etc/docker/daemon.json  ##加入相关国内镜像地址。

{
  "registry-mirrors" : ["https://4mii0w1b.mirror.aliyuncs.com","https://registry.docker-cn.com"]
}
