1. cobbler简介cobbler官网：http://cobbler.github.io/
Cobbler是一个Linux服务器安装的服务，可以通过网络启动(PXE)的方式来快速安装、重装物理服务器和虚拟机，同时还可以管理DHCP，DNS等。
Cobbler可以使用命令行方式管理，也提供了基于Web的界面管理工具(cobbler-web)，还提供了API接口，可以方便二次开发使用。
Cobbler是较早前的kickstart的升级版，优点是比较容易配置，还自带web界面比较易于管理。
Cobbler内置了一个轻量级配置管理系统，但它也支持和其它配置管理系统集成，如Puppet，暂时不支持SaltStack。

创建一个虚拟机，模式和服务端模式一样，（这里我使用的是nat，所以要安装的虚拟机模式也是nat），然后设置虚拟机
然后，直接开启虚拟机，看到以下界面，选择第二个，回车，然后等待系统自动安装完成即可。
因为这种方式需要手动选择，如果机器太多，每台服务器都要选择，还是很麻烦，所以采用web界面配置定制安装
# 配置完成后可能导致访问不了web页面，猜测python-django版本有问题
[root@localhost ~]# yum -y install python2-pip
[root@localhost ~]# pip install --upgrade pip
[root@localhost ~]# pip install Django==1.9.13
#用pip安装指定版本的Django重启httpd服务 ，再次访问https://192.168.100.96/cobbler_web出现登录页面
定制安装步骤：
mac地址在：虚拟机—编辑此虚拟机—网路适配器—高级—MAC地址（点击生成然后复制即可）
直接开启此虚拟机，它就会自动安装
