一、系统环境：
CentOS5.6 32位
二、软件：
cobbler dhcp httpd xinetd tftp-server
三、具体实施：
1.安装rpmforce源
wget http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.i386.rpm
rpm -ivh rpmforge-release-0.5.2-2.el6.rf.i686.rpm
2.安装相关软件
yum -y install cobbler dhcp httpd xinetd tftp-server
3.修改一下配置文件：
/var/lib/cobbler/settings 中的 server 和 next_server 对应的127.0.0.1修改为本服务器的 IP 地址，
manage_dhcp 设为 1，以便管理 DHCP；将 /etc/xinetd.d/tftp 中 disable = no。
4.导入ISO文件
mkdir -p /mnt/iso
mount -o loop /dev/cdrom /mnt/iso
cobbler import --mirror=/mnt/iso --name=CentOS-1.0-i386
5.查看导入结果
cobbler distro list
6.修改 DHCP 和 Kickstart 配置模板
a.修改DHCP配置模板
vi /etc/dhcpd.conf
vi /etc/cobbler/dhcp.template
以上两个文件的内容相同
b.修改 Kickstart 配置模板
mv /var/www/cobbler/kickstarts/CentOS-1.0-i386/ks.cfg /var/www/cobbler/kickstarts/CentOS- 1.0-i386/ks.cfg.bak
mv /var/www/cobbler/kickstarts/CentOS-1.0-xen-i386/ks.cfg /var/www/cobbler/kickstarts/CentOS- 1.0-xen-i386/ks.cfg.bak
vi /etc/cobbler/default.ks
vi /var/www/cobbler/kickstarts/kerryOS-1.0-i386/ks.cfg
vi /var/www/cobbler/kickstarts/kerryOS-1.0-xen-i386/ks.cfg
以上三个文件的内容相同

7.生成并同步所有配置
cobbler sync
8.启动相关的服务
/etc/init.d/httpd start
/etc/init.d/xinetd start
/etc/init.d/dhcpd start
/etc/init.d/cobblerd start
chkconfig --level 35 httpd on
chkconfig --level 35 xinetd on
chkconfig --level 35 dhcpd on
chkconfig --level 35 cobblerd on
9.记得关闭防火墙和selinux
10.客户端通过PXE安装系统
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。
