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。

kickstart 是由 dhcp、tftp、http 这三种服务有机组成,为有 pxe 功能的客户端提供自动装机服务。kickstart 只是这套系统的名字,并没有这个独立的软件。
cobbler 是对 kickstart 进行二次开发,安装 cobbler 的过程中,其实已经悄悄地安装了和 kickstart 一样的服务,因此在工作中安装 cobbler 直接一条 yum 命令即可,不需要先把 kickstart 服务安装配置好。

配置 Cobbler
[root@CentOS6 ~]# 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 set to something other than 127.0.0.1, and should match the IP of the boot server on the PXE 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 th
em, 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 : change ‘disable’ to ‘no’ in /etc/xinetd.d/rsync
6 : file /etc/xinetd.d/rsync does not exist  # 这是一个 bug
7 : debmirror package is not installed, it will be required to manage debian deployments and repositories
8 : The default password used by the sample templates for newly installed machines (default_password_crypted in /etc/cobb
ler/settings) is still set to ‘cobbler’ and should be changed, try: “openssl passwd -1 -salt ‘random-phrase-here’ ‘your-password-here'” to generate new one9 : 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.
