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)，是用来给轻量文件传输的

1: reposync is not installed, install yum-utils or dnf-plugins-core
2: yumdownloader is not installed, install yum-utils or dnf-plugins-core
3: debmirror package is not installed, it will be required to manage debian deployments and repositories
4: fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them

Restart cobblerd and then run 'cobbler sync' to apply changes.
