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。
cobbler的工作流程;

配置cobbler：
1 准备环境：
（1）所选主机需有2个网卡，其中一个为静态ip且仅主机模式；另一个为dhcp获取的桥接模式，可获取yum源。
（2）禁用selinux，关闭防火墙。
iptables -F
[root@centos7 ~]#getenforce
Permissive
（3）安装各种所需服务并启用
yum install dhcp cobbler cobbler-web
systemctl enable dhcpd （该服务会被cobbler接管，在cobbler配置文件中可以配置）
systemctl enable httpd
systemctl enable tftpd
systemctl enable cobblerd
systemctl start dhcpd
systemctl start httpd
systemctl start tftpd
systemctl start cobblerd
2 更改cobbler的配置文件
在更改文件的时候最好备份一份，防止破坏文件无法恢复。
vim /etc/cobbler/settings
(1) 文件的384行：
server: 192.168.52.142 -----------》改成仅主机模式的那块网卡的ip
（2）文件的272行：
next_server: 192.168.52.142---------》同上
（3）文件的242行 ：
manage_dhcp: 1 ------------------》原文件为0，改成1，表示dhcp服务由cobler接管。
（4）更改完文件后需输入命令 cobbler sync 写入 ；
可用cobbler check 检查有无遗漏。
[root@centos7 ~]#cobbler check
The following are potential configuration items that you may want to fix:
1 : SELinux is enabled. Please review the following wiki page for details on ensuring cobbler works correctly in your SELinux environment:
https://github.com/cobbler/cobbler/wiki/Selinux
2 : enable and start rsyncd.service with systemctl
3 : debmirror package is not installed, it will be required to manage debian deployments and repositories
4 : 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.
（5）此时去查看dhcp服务的配置文件会显示已被cobbler接管。
[root@centos7 ~]#cat /etc/dhcp/dhcpd.conf
# ******************************************************************
# Cobbler managed dhcpd.conf file
# generated from cobbler dhcp.conf template (Mon Jul 24 07:19:37 2017)
# Do NOT make changes to /etc/dhcpd.conf. Instead, make your changes
# in /etc/cobbler/dhcp.template, as /etc/dhcpd.conf will be
# overwritten.
# ******************************************************************
3 下载加载程序并导入光盘
cobbler get-loaders
cobbler sync
systemctl restart cobblerd.service
cobbler import --path=/misc/cd --name=centos7.3
cobbler import --path=/misc/cd --name=centos6.9
cobbler sync
导入完成后
[root@centos7 ~]#cobbler distro list
centos6.9-x86_64
centos7.3-x86_64
自动回生成2个ks文件，默认为最小化安装。
