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)

3. 客户端安装
新建虚拟机从pxe启动,若出现以下界面则表示成功:
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:
[root@localhost ~]# cobbler sync [root@localhost ~]# systemctl restart httpd [root@localhost ~]# systemctl restart cobblerd [root@localhost ~]# systemctl restart xinetd
