[[email protected] ~]#rpm -Uvh http://mirrors.hustunique.com/epel/6/x86_64/epel-release-6-8.noarch.rpm   #导入epel源

[[email protected] ~]#yum -y install httpd rsync tftp-server xinetd dhcp python-ctypes cman pykickstart   #安装cobbler依赖的包

[[email protected] ~]#yum -y install cobbler* debmirror*  #安装cobbler

[[email protected] ~]# cobbler check                    #检查cobbler配置
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 : some network boot-loaders are missing from /var/lib/cobbler/loaders, you may run ‘cobbler get-loaders‘ to download them, or, 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, elilo.efi, and yaboot. The ‘cobbler get-loaders‘ command is the easiest way to resolve these requirements. 
4 : change ‘disable‘ to ‘no‘ in /etc/xinetd.d/rsync 
5 : comment out ‘dists‘ on /etc/debmirror.conf for proper debian support 
6 : comment out ‘arches‘ on /etc/debmirror.conf for proper debian support 
7 : 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

Restart cobblerd and then run ‘cobbler sync‘ to apply changes.

配置完成现在可以装机了，因为是虚拟机测试，当然先新建虚拟机，注意客户端要和cobbler server 都是桥接，os启动默认是以pxe启动的。

然后点击开启虚拟机

选择centos6.6我们就可以开始装机了，搞定。

当然我们也可以通过web的方式哦

导入cobbler

点击run就行了。

最后大概说下cobbler

Cobbler由python语言开发，是对PXE和 Kickstart以及DHCP的封装。

融合很多特性，提供了CLI和Web的管理形式。更加方便的实行网络安装。

同时，Cobbler也提供了API接口，使用其它语言也很容易做扩展。

它不仅可以安装物理机，同时也支持kvm、xen虚拟化、Guest OS的安装。

更多的是它还能结合Puppet等集中化管理软件，实现自动化的管理。

PXE 预启动执行环境（Preboot eXecution Environment，PXE，也被称为预执行环境)是让计算机通过网卡独立地使用数据设备(如硬盘)或者安装操作系统。

Cobbler提供以下服务集成：

* PXE服务支持

* DHCP服务管理

* DNS服务管理

* 电源管理

* Kickstart服务支持

* yum仓库管理

以下是cobbler命令及配置文件的一些说明

1.cobbler命令说明

cobbler check：检查cobbler配置

cobbler list：列出所有的cobbler元素

cobbler report：列出元素的详细信息

cobbler distro:查看导入的发行版系统信息

cobbler system：查看添加的系统信息

cobbler profile：查看配置信息

cobbler sync：同步cobbler配置

cobbler reposync：同步yum仓库

2.cobbler配置文件说明：

/etc/cobbler/seetings cobbler的主配置文件

/etc/cobbler/users.digest 用于web访问的用户名密码配置文件

/etc/cobbler/modules.conf 模块配置文件

/etc/cobbler/users.conf cobbler webui/web服务授权配置文件

/etc/cobbler/iso/ buildiso模板配置文件

/etc/cobbler/power 电源配置文件

/etc/cobbler/pxe pxeprofile配置模板

/etc/cobbler 此目录包含rsync,dhcp,dns,pxe,等服务的模板配置文件

3.系统镜像数据目录/var/www/cobbler

导入的系统发行版，repos镜像和kickstart文件都放置在/var/www/cobbler目录下

/var/www/cobbler/images存储所有导入发行版的kernel和initrd镜像用于远程网络启动

/var/www/cobbler/ks_mirror存储导入的发行版系统数据

/var/www/cobbler/repo_mirror 仓库存储目录

/var/log/cobbler cobbler日志文件

4.cobbler数据目录/var/lib/cobbler

/var/lib/cobbler/config/存放distros，repos，systems，和profile等信息配置文件，一般是json文件

/var/lib/cobbler/snippets存放ks文件可以导入的脚本小片段

/var/lib/cobbler/triggers存放用户定义的cobbler命令

/var/lib/cobbler/kickstarts/存放kictstart配置文件
