Install Cobbler
前言
Cobbler 是一款 Linux 系统安装与配置软件
Cobbler is a Linux installation server that allows for rapid setup of network installation environments. It glues together and automates many associated Linux tasks so you do not have to hop between many various commands and applications when deploying new systems, and, in some cases, changing existing ones. Cobbler can help with provisioning, managing DNS and DHCP, package updates, power management, configuration management orchestration, and much more.
可以实现 Linux 的自动化部署与初始化配置，在需要安装大量 OS 的场景下，可以极大提升效率
这里分享一下 Cobbler 的安装方法
Tip: 当前的版本为 LATEST VERSION: 2.8.2 released on Sep 16th 2017

# this is the address of the cobbler server -- as it is used
# by systems during the install process, it must be the address

next_server: 192.168.56.201
[root@56-201 cobbler]#由于在 PXE 引导的过程中 dhcp 服务器可以作为一个独立的角色与 cobbler 分别布到不同的节点上，因此这里的 IP 不一定是本机 IP，但是为了方便，我希望 cobbler 一同管理 dhcp，所以我也准备将 dhcp 服务与 cobbler 放在一起 (cobbler 已经集成了直接管理 dhcp 的功能)
管理 dhcp
[root@56-201 cobbler]# vim settings
[root@56-201 cobbler]# grep -B 4 '^manage_dhcp' settings
# set to 1 to enable Cobbler's DHCP management features.
# the choice of DHCP management engine is in /etc/cobbler/modules.conf
#manage_dhcp: 0
manage_dhcp: 1
[root@56-201 cobbler]#默认 cobbler 是不管理 dhcp 的
但是我们通过配置 manage_dhcp 选项，可以打开管理

Restart cobblerd and then run 'cobbler sync' to apply changes.
[root@56-201 cobbler]#这些多是建议，服务类型的比如 tftp 和 rsync 是需要遵从的，否则 cobbler 可能会工作不正常，但是其它，比如 debmirror 和 fence 如果用不上，是可以不用理会的
SELinux 在重启 OS 后会自动满足条件，可以忽略掉
