2.拉包
2.1修改yum配置文件
cat /etc/yum.repos.d/docker-ce.repo

2.2创建本地仓库
mkdir -p /data/yum/data/BaseOS/Packages
2.3拉包
yum update
yum clean all
yum makecache
#注: 此命令并不是全量下载依赖包以及安装包，而是检测 系统未安装 的包 才会下载
yum install --downloadonly --downloaddir=/data/yum/data/BaseOS/Packages/ docker-ce kubelet-1.23.5 kubeadm-1.23.5 kubectl-1.23.5
#如果想强制下载某个已安装的包,需使用以下命令
yum reinstall --downloadonly --downloaddir=/data/yum/data/BaseOS/Packages/ libtevent
2.4安装包全览
用2.3方法可以按需下载包
本人整个安装过程用到的包大约如下:

3.本地仓库建立
cd /data/yum/data/
createrepo .
#如果有新增包放进/data/yum/data/BaseOS/Packages/，可用如下命令更新
cd /data/yum/data/
createrepo --update .
4.yum客户端配置
