cobbler
cobbler
简介
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。
Cobbler官网：http://cobbler.github.io/
cobbler集成的服务
- PXE服务支持
- DHCP服务管理
- DNS服务管理(可选bind,dnsmasq)
- 电源管理
- Kickstart服务支持
- YUM仓库管理
- TFTP(PXE启动时需要) Apache(提供kickstart的安装源，并提供定制化的kickstart配置)，是用来给轻量文件传输的

[root@localhost cobbler]# cobbler check //检查一下错误问题
The following are potential configuration items that you may want to fix:
1 : 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.
2 : debmirror package is not installed, it will be required to manage debian deployments and repositories
3 : 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.
第二个与第三个问题是关于debian系统的错误可以忽略
安装包fence-agents解决第三个问题
[root@localhost cobbler]# yum -y install fence-agents
在CentOS8传输文件到CentOS7中解决第一个问题
