Cobbler是一个快速网络安装linux的服务，而且在经过调整也可以支持网络安装windows。该工具使用python开发，小巧轻便（才15k行代码），使用简单的命令即可完成PXE网络安装环境的配置，同时还可以管理DHCP，DNS，以及yum包镜像。
Cobbler支持命令行管理，web界面管理，还提供了API接口，可以方便二次开发使用
# yum install cobbler 安装cobbler # service httpd start 文件服务器 [root@MinR dhcp]# service cobblerd start 启动cobbler [root@node3 ~]# cobbler check 检查cobbler环境是否正常 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 : 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. 4 : change ‘disable‘ to ‘no‘ in /etc/xinetd.d/rsync 5 : debmirror package is not installed, it will be required to manage debian deployments and repositories 6 : ksvalidator was not found, install pykickstart 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
可以看到这里一共有8个报错，要挨个手动修复

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.
