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官网：http://cobbler.github.io/
cobbler集成的服务
- PXE服务支持
- DHCP服务管理
- DNS服务管理(可选bind,dnsmasq)
- 电源管理
- Kickstart服务支持
- YUM仓库管理
- TFTP(PXE启动时需要)
- Apache(提供kickstart的安装源，并提供定制化的kickstart配置)

- 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：
PS:账号密码都为cobbler
步骤：
- 添加网卡，网卡名eth0
- 选择第1步添加的网卡
- 填写要安装的服务器的MAC地址
- 安装好后给此服务器分配的IP地址
- 设置子网掩码
- 确认添加
