【实验需求】

为了提高公司内部服务器下载软件包的速度，同时也不占用网络带宽，需要在内网部署一台私有的 YUM 服务，将阿里云镜像源的相关镜像保存到本地，公司其它内网服务器的 YUM 源均指向该私有 YUM 仓库。

【实验环境】

client2                   192.168.119.145

【实验过程】

1、安装 Cobbler及其相关的服务和组件

# Cobbler 依赖与epel源，安装前需要先配好epel源
[root@repo-mirror-server ~]# yum -y install cobbler
[root@repo-mirror-server ~]# systemctl enable --now cobblerd httpd

2、使用阿里云 zabbix 的源为例进行测试
