脚本：Cobbler Center – 自动部署【离线】 – Bash Shell版本

By Adamhuan | 2018年6月9日

本文从零开始详细描述一个Cobbler Center的自动部署脚本是如何建立起来的。

手动安装部分参考之前的文档：
http://d-prototype.com/archives/6843

首先，开启服务器的YUM源缓存：

[root@localhost ~]# cat /etc/yum.conf | grep keepcache
keepcache=1
[root@localhost ~]#

[root@localhost ~]# cat /etc/yum.conf | grep keepcache

keepcache=1

[root@localhost ~]#
