#添加镜像文件时默认关联cfg文件，文件路径为/var/lib/cobbler/kickstart/sample_end.cfg
#可以直接使用默认文件进行安装！此处修改关联ks文件，
[root@~]# cobbler profile edit --name=Centos6.7-x86_64 --kickstart=/var/lib/cobbler/kickstarts/Centos6.cfg
[root@~]# cobbler sync #每次修改设置后执行同步操作生效
[root@~]# service httpd restart

安装kickstart程序可以自定义自己需要的ks文件：
[root@~]# yum install -y system-config-kickstart
