Cobbler是一个快速网络安装linux的服务，而且在经过调整也可以支持网络安装windows。该工具使用python开发，小巧轻便（才15k行代码），使用简单的命令即可完成PXE网络安装环境的配置，同时还可以管理DHCP，DNS，以及yum包镜像。
我用的系统是Centos6.5 64 位
配置epel yum源
我这用阿里云的epel
mv /etc/yum.repos.d/epel.repo /etc/yum.repos.d/epel.repo.backup
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo安装cobbler需要的服务
yum install dhcp tftp rsync xinetd httpd关闭selinux和防火墙自己做测试为了不影响就关了

*** TASK COMPLETE ***在检查配置
[root@i51 ~]# cobbler check
The following are potential configuration items that you may want to fix:
1 : The 'server' field in /etc/cobbler/settings must be set to something other than localhost, or kickstarting features will not work. This should be a resolvable hostname or IP for the boot server as reachable by all machines that will use it.
2 : For PXE to be functional, the 'next_server' field in /etc/cobbler/settings must be set to something other than 127.0.0.1, and should match the IP of the boot server on the PXE network.
3 : change 'disable' to 'no' in /etc/xinetd.d/rsync
4 : debmirror package is not installed, it will be required to manage debian deployments and repositories
5 : ksvalidator was not found, install pykickstart
6 : The default password used by the sample templates for newly installed machines (default_password_crypted in /etc/cobbler/settings) is still set to 'cobbler' and should be changed, try: "openssl passwd -1 -salt 'random-phrase-here' 'your-password-here'" to generate new one
7 : 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.上面这段信息大意就是：
1，编辑/etc/cobbler/settings文件，找到 server选项，修改为适当的ip地址，本实例配置ip为：192.168.1.243
2，编辑/etc/cobbler/settings文件，找到 next_server选项，修改为适当的ip地址，本实例配置ip为：192.168.1.243
3，编辑/etc/xinetd.d/rsync文件，将文件中的disable字段的配置由yes改为no
4，提示说debmirror没安装。如果不是安装 debian之类的系统，此提示可以忽略，如果需要安装，下载地址为：
http://rpmfind.net/linux/rpm2html/search.php?query=debmirror5，ksvalidator没有被发现，安装pykickstart
[root@i51 ~]# yum install pykickstart6，修改cobbler用户的默认密码，可以使用如下命令生成密码，并使用生成后的密码替换/etc/cobbler/settings中的密码。生成密码命令： 其中“random-phrase-here”为干扰码
openssl passwd -1 -salt 'random-phrase-here' 'your-password-here'7，fencing tools为找到安装
[root@i51 ~]# yum install fence-agentsOK再来执行检查
[root@i51 ~]# cobbler check

Starting cobbler daemon: [ OK ]cobbler使用 导入安装文件
总体来说，在RHT/Centos 系列版本下，Cobbler的使用上不会遇到很大问题
Cobbler 主要的作用是，把DHCP 、Kickstart 的修改都集成在一个平台下做了管理
Cobbler 的精华 其实是 它启用了 Kickstart 配置模板，其中可以内嵌python代码
这部分技术，Cobbler叫做：snippets
在RHT/Centos 系列中，官方已经提供了不少这些代码，基本上调用一下就可以了，而Ubuntu下就非常的痛苦，必须自己开发（这部分的配置 暂且不表，后续有专门篇幅来介绍 )
以下是相关配置路径(默认安装) :
Cobbler 配置主要位置：/var/lib/cobbler/ （实际操作和配置的目录 )
snippets 代码 位置：/var/lib/cobbler/snippets/
Kickstart 模板 位置 : /var/lib/cobbler/kickstarts/
安装源镜像 位置 : /var/www/cobbler/ks_mirror/ （把它link到apache的发布目录，方便kickstart 工作时通过http下载安装镜像文件 )
导入安装源
准备好安装光盘 (ISO)我的服务器上有这么多

*** TASK COMPLETE ***参数说明:
--name 为安装源定义一个名字
--arch 指定安装源是32位还是64位、ia64, 目前支持的选项有: x86│x86_64│ia64
注意： 这个安装源的唯一标示 就是根据这两个参数来定义
本例导入成功后，安装源的唯一标示就是：centos6.3-x86_64 ，如果重复，系统会提示导入失败
更多用法，可以查看官方文档: man cobbler ,然后查找 import 的配置
相关管理命令:
//查看导入源库列表
[root@i51 镜像]# cobbler distro list
CentOS6.5-x86_64配置dhcp服务
首先修改cobbler配置，让cobbler来管理dhcp服务，编辑文件/etc/cobbler/settings
manage_dhcp: 1接下来修改/etc/cobbler/dhcp.template，此文件是cobbler管理dhcp的模板
本例中只需要修改如下部分
subnet 192.168.1.0 netmask 255.255.255.0 {
option routers 192.168.1.1;
option domain-name-servers 192.168.1.1;
option subnet-mask 255.255.255.0;
range dynamic-bootp 192.168.1.30 192.168.1.80;
default-lease-time 21600;
max-lease-time 43200;
next-server $next_server;
class "pxeclients" {
match if substring (option vendor-class-identifier, 0, 9) = "PXEClient";
if option pxe-system-type = 00:02 {
filename "ia64/elilo.efi";
} else if option pxe-system-type = 00:06 {
filename "grub/grub-x86.efi";
} else if option pxe-system-type = 00:07 {
filename "grub/grub-x86_64.efi";
} else {
filename "/pxelinux.0";
}
}
}IP地址段根据你实际环境中的给定
其他可以不用改

*** TASK COMPLETE ***cobbler会自动进行初始化工作，移除已经存在的启动项，然后根据模板拷贝loader文件。之后再生成pxe的配置文件，生成dhcp的配置文件，最后再重启dhcp服务。
至此，就可以使用虚拟机来测试cobbler安装了。
OK开启真机或者虚拟机来测试注意开启网络引导 网卡要开启PXE 引导程序
测试如下
登陆后如下默认root密码为cobbler
# 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=192.168.1.243
