cobbler
1. cobbler简介
Cobbler是一个Linux服务器安装的服务，可以通过网络启动(PXE)的方式来快速安装、重装物理服务器和虚拟机，同时还可以管理DHCP，DNS等。
Cobbler可以使用命令行方式管理，也提供了基于Web的界面管理工具(cobbler-web)，还提供了API接口，可以方便二次开发使用。
Cobbler是较早前的kickstart的升级版，优点是比较容易配置，还自带web界面比较易于管理。
Cobbler内置了一个轻量级配置管理系统，但它也支持和其它配置管理系统集成，如Puppet，暂时不支持SaltStack。

cobbler命令详解
cobbler check //核对当前设置是否有问题
cobbler list //列出所有的cobbler元素
cobbler report //列出元素的详细信息
cobbler sync //同步配置到数据目录,更改配置最好都要执行下
cobbler reposync //同步yum仓库
cobbler distro //查看导入的发行版系统信息
cobbler system //查看添加的系统信息
cobbler profile //查看配置信息

4. 定制安装
定制安装步骤：
- 统计服务器mac地址
- 配置cobbler
- 安装
统计mac地址此处就不赘述了，直接最重要的配置
在 cobbler 的web界面上配置：
同步配置并重启相关服务：
