**1\.** **备份现有的** **YUM** **仓库配置文件**
首先,建议备份现有的 YUM 仓库配置文件,以防万一需要恢复。

**2\.** **下载新的** **YUM** **仓库配置文件**
你可以从 CentOS 官方或其他可靠的镜像源网站下载新的 YUM 仓库配置文件。但是,对于 CentOS 7,通常的做法是编辑现有的文件或创建新的文件来指定新的镜像源。
**方法一:编辑现有的文件**
如果只想修改现有的仓库(如 base, updates, extras),你可以直接编辑这些文件。但是,由于你已经备份了它们,你可以选择删除它们并创建新的。
**方法二:创建新的** **YUM** **仓库配置文件**
你可以创建一个或多个.repo文件在/etc/yum.repos.d/目录下,每个文件代表一个或多个仓库。
以下是一个示例,展示了如何为 CentOS 7 的 base, updates, extras 和 epel 仓库创建新的.repo文件:
**bash**复制代码

**3\.** **清理** **YUM** **缓存并测试**
在修改了 YUM 仓库配置文件后,你需要清理 YUM 的缓存,并尝试搜索一些包来测试新的仓库是否工作正常。
**bash**复制代码

如果yum repolist命令成功显示了仓库列表,并且没有错误消息,那么你的 YUM 镜像源就已经成功更换了
<hr/>
4\.**安装必要的软件包以及设置 Docker 的稳定仓库**:
**yum install -y yum-utils device-mapper-persistent-data lvm2 && \\**
**yum-config-manager --add-repo [**http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo**](http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo)
<hr/>
5.**安装Docker CE**:
sudo dnf install -y docker-ce docker-ce-cli containerd.io
<hr/>
6.**启动 Docker 服务并设置开机自启**:
sudo systemctl start docker
sudo systemctl enable docker
sudo systemctl status docker
#查看版本号
docker -v
