cobbler安装
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工作流程
Server端:
启动Cobbler服务
进行Cobbler错误检查,执行cobbler check命令
进行配置同步,执行cobbler sync命令
复制相关启动文件文件到TFTP目录中
启动DHCP服务,提供地址分配
DHCP服务分配IP地址
TFTP传输启动文件
Server端接收安装信息
Server端发送ISO镜像与Kickstart文件
Client端:
客户端以PXE模式启动
客户端获取IP地址
通过TFTP服务器获取启动文件
进入Cobbler安装选择界面
客户端确定加载信息
根据配置信息准备安装系统
加载Kickstart文件
传输系统安装的其它文件
进行安装系统
