通过 cobbler check 核对当前设置是否有问题
[root@localhost ~]# cobbler check
The following are potential configuration items that you may want to fix:
1 : debmirror package is not installed, it will be required to manage debian deployments and repositories
2 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them
以上两个是关于 debian 系统的错误，请忽略
-
配置 cobbler dhcp
-
修改 cobbler 配置文件，让 cobbler 控制 dhcp
[root@localhost ~]# vim /etc/cobbler/dhcp.template
