cobbler是一个linux系统安装的服务，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Apl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下载及启动

[root@Cobbler ~]# yum -y install cobbler cobbler-web dhcp tftp-server pykickstart httpd python-django

[root@Cobbler ~]# systemctl start cobblerd.service
[root@Cobbler ~]# systemctl start httpd.service

根据检查配置文件来修改cobbler配置文件

[root@Cobbler ~]# 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 s to something other than 127.0.0.1, and should match the IP of the boot server on the ▽XE network.
3 : change ‘disable‘ to ‘no‘ in /etc/xinetd.d/tftp
4 : 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.
5 : enable and start rsyncd.service with systemctl
6 : debmirror package is not installed, it will be required to manage debian deployments and repositories
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
8 : 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.

备份
[root@Cobbler ~]# cp /etc/cobbler/settings{,.ori}

快速修改配置文件

sed -i ‘s/server: 127.0.0.1/server: 172.16.1.202/‘ /etc/cobbler/settings
sed -i ‘s/next_server: 127.0.0.1/next_server: 172.16.1.202/‘ /etc/cobbler/settings
sed -i ‘s/manage_dhcp: 0/manage_dhcp: 1/‘ /etc/cobbler/settings
sed -i ‘s/pxe_just_once: 0/pxe_just_once: 1/‘ /etc/cobbler/settings
sed -ri "/default_password_crypted/s#(.: ).#\1\"openssl passwd -1salt‘oldboy‘‘123456‘\"#"/etc/cobbler/settings
