next_server：<服务器的 IP 地址>
server：<服务器的 IP 地址>
选项 manage_* 和 restart_* 无需加以说明。选项 next_server 用在 DHCP 配置文件中，向客户端告知提供引导文件的服务器地址。选项 server 在客户端安装期间用于引用 Cobbler 服务器地址。最后，选项 pxe_just_once 预防将机器中的安装循环配置为始终从网络引导。激活此选项时，机器告诉 Cobbler 安装已完成。Cobbler 将系统对象的 netboot 标志更改为 false，这会强制机器从本地磁盘引导。好了，下面我们配置并管理dhcp服务与http服务。
1.让Cobbler来管理DHCP服务器
[root@node2 ~]# vim /etc/cobbler/settings
manage_dhcp: 1
2.修改DHCP模板
[root@node2 ~]# vim /etc/cobbler/dhcp.template
subnet 192.168.18.0 netmask 255.255.255.0 {
option routers 192.168.18.254;
option domain-name-servers 8.8.8.8;
option subnet-mask 255.255.255.0;
range dynamic-bootp 192.168.18.221 192.168.18.225;
filename "/pxelinux.0";
default-lease-time 21600;
max-lease-time 43200;
next-server $next_server;
}
3.重新启动Cobbler服务
[root@node2 ~]# service cobblerd restart
Stopping cobbler daemon: [确定]
Starting cobbler daemon: [确定]
4.编辑/etc/httpd/conf.d/wsgi.conf 去掉注释
[root@node2 ~]# vim /etc/httpd/conf.d/wsgi.conf
LoadModule wsgi_module modules/mod_wsgi.so
5.完成后一定要运行cobbler sync 命令让配置生效，使dhcp、http被cobbler接管，不然会报错。
[root@node2 ~]# cobbler sync

好了，到这里我们的Cobbler安装与配置就讲解完成了，我们在下一篇博客中将讲解Cobbler管理与使用详解。最后，希望大家有所收获^_^……
