本文主要是介绍cobbler，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！
cobbler简介
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
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
批量装机 cobbler
PXE的基础上进行封装
-
优点
较早前的kickstart的升级版，容易配置， 自带web界面比较易于管理 内置了一个轻量级配置管理系统， 支持和其它配置管理系统集成
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)
cobbler服务端部署
#关闭防火墙和selinux
[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# systemctl disable firewalld
Removed /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

#下面查是查不到的，所以需要添加模块再去查找就看见了
[root@localhost ~]# dnf list all |grep cobbler
[root@localhost ~]# dnf module enable cobbler

The following are potential configuration items that you may want to fix:
1: debmirror package is not installed, it will be required to manage debian deployments and repositories
2: 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. #这两个问题可以进行忽略
