//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: some network boot-loaders are missing from /var/lib/cobbler/loaders. If you only want to handle x86/x86_64 netbooting, you may ensure that you have installed a *recent* version of the syslinux package installed and can ignore this message entirely. Files in this directory, should you want to support all architectures, should include pxelinux.0, menu.c32, and yaboot.
2: debmirror package is not installed, it will be required to manage debian deployments and repositories
3: 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.
//第一个问题我们已经解决过了，第二第三个问题是在Debian系统上面需要注意的，解决办法是在Debian系统上面安装fence-agents，可以忽略


//配置DHCP模板文件
[root@localhost ~]# vim /etc/cobbler/dhcp.template
subnet 192.168.169.0 netmask 255.255.255.0 {
     option routers             192.168.169.2;
     option domain-name-servers 8.8.8.8;
     option subnet-mask         255.255.255.0;
     range dynamic-bootp        192.168.169.143 192.168.169.153;		//地址池，视情况而定
     default-lease-time         21600;
     max-lease-time             43200;
     next-server                $next_server;

手动安装
创建一个虚拟机，然后打开虚拟机，等待dhcp分配完毕，选择想要使用的镜像
