    Cobbler简介

    Cobbler官网

    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)

The following are potential configuration items that you may want to fix:

1: some network boot-loaders are missing from /var/lib/cobbler/loaders. 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, and yaboot.
2: reposync is not installed, install yum-utils or dnf-plugins-core
3: yumdownloader is not installed, install yum-utils or dnf-plugins-core
4: debmirror package is not installed, it will be required to manage debian deployments and repositories
5: 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.

#问题1的解决方法
[root@localhost ~]# yum -y install syslinux*
[root@localhost ~]# cp /usr/share/syslinux/pxelinux.0 /var/lib/cobbler/loaders/
[root@localhost ~]# cp /usr/share/syslinux/menu.c32 /var/lib/cobbler/loaders/
[root@localhost ~]# ls /var/lib/cobbler/loaders/
menu.c32  pxelinux.0

#问题2和3的解决方法
[root@localhost ~]# yum -y install yum-utils

#解决后再次检查可以发现还报问题1，如果你已完成问题1的解决方法可以不理
[root@localhost ~]# cobbler check

    新建一台虚拟机，设置好cpu，内存等配置，无需自行添加镜像。创建好直接开启虚拟机。

    需耐心等待，出现如下界面，选择刚刚制作的镜像
