1. 安装相关软件:

wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.1-1.el5.rf.x86_64.rpm  
rpm -ivh rpmforge-release-0.5.1-1.el5.rf.x86_64.rpm
yum -y install cobbler tftp-server dhcp httpd xinetd

注意 /var/www/cobbler 目录必须具有足够容纳 Linux 安装文件的空间(移动,建软链接)
#ln -s /data/cobbler /var/www

2. 检查 cobbler 配置:

cobbler check

按提示解决相关问题,把 /var/lib/cobbler/settings 中的 server 和 next_server 设为本服务器的 IP 地址,manage_dhcp 设为 1,以便管理 DHCP
 将 /etc/xinetd.d/tftp 中 disable = no

3. 导入CentOS 安装 DVD ISO 中的文件:

mount -o loop /home/dtm/CentOS-5.5-x86_64-bin-DVD.iso /mnt/iso       # 将ISO文件挂载到 /mnt/iso 目录
cobbler import --mirror=/mnt/iso --name=centos5.5                    # 从 /mnt/iso目录导入所有安装文件,命名为 centos5.5
cobbler distro list                                                                                      # 查看导入结果

[root@elain www]# cobbler distro list
  centos5.5-x86_64
  centos5.5-xen-x86_64

-------------------------------
cobbler目录及文件

cobbler相关配置文件: /etc/cobbler
cobbler数据存储目录: /var/www/cobbler
dhcp配置文件: /etc/dhcpd.conf
dhcp租期缓存文件: /var/lib/dhcpd/dhcpd.leases
pxe配置文件: /tftpboot/pxelinux.cfg/default
ks模板文件: /var/lib/cobbler/kickstarts
--------------------------------
4. 修改 DHCP 和 Kickstart 配置模板:

vi /etc/cobbler/dhcp.template                 # DHCP 配置模板,根据提示修改下面模板
################################
ddns-update-style interim;

allow booting;
allow bootp;

ignore client-updates;
set vendorclass = option vendor-class-identifier;

subnet 192.168.8.0 netmask 255.255.255.0 {
     option routers          192.168.8.92;
     option subnet-mask      255.255.255.0;
     range dynamic-bootp     192.168.8.10 192.168.8.254;
     filename                "/pxelinux.0";
     default-lease-time      21600;
     max-lease-time          43200;
     next-server             192.168.8.92;
}

5. 生成并同步所有配置:

cobbler sync

注:每次更改Kickstart 配置文件,都需要使用cobbler sync重新同步所有配置

6. 启动相关服务:

/etc/init.d/httpd start
/etc/init.d/xinetd start
/etc/init.d/dhcpd start
/etc/init.d/cobblerd start

7.客户端启动PXE 安装

启动另一台新服务器,通过 PXE 启动进入,提示"boot:"时输入"menu"即可进入蓝色的 Cobbler 安装界面,选择安装项,自动完成系统安装。

http方式安装:服务器:192.168.9.101 目录:/cobbler/ks_mirror/centos/

8.重装系统:

在要重装的机器安装koan  
yum install koan  
查看cobbler服务器有哪些安装盘  
koan --list-profiles --server=192.168.9.101
选择要重装的系统并重启  
koan --replace-self --server=192.168.9.101 --profile=centos5.5
reboot  

附上服务控制脚本:
[root@elain ~]# cat cobbler.sh
#!/bin/sh
# created by dingtm
# date: 2010.12.31

case $1 in
        start)
               /etc/init.d/httpd start
               /etc/init.d/xinetd start
               /etc/init.d/dhcpd start
               /etc/init.d/cobblerd start
                ;;
        stop)
               /etc/init.d/httpd stop
               /etc/init.d/xinetd stop
               /etc/init.d/dhcpd stop
               /etc/init.d/cobblerd stop
                ;;
        status)
                /etc/init.d/httpd status
                /etc/init.d/xinetd status
                /etc/init.d/dhcpd status
                /etc/init.d/cobblerd status
                ;;     
         sync)
                cobbler sync
                ;;                          
        *)
                echo "Input error,please in put 'start|stop|status|sync'!";
                exit 2>&1 >/dev/null &
                ;;
        esac
