cobbler介紹
Cobbler是一個Linux系統安裝的服務，可以通過網絡啟動(PXE)的方式來快速安裝、重裝物理服務器和虛擬機，同時還可以管理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)，還提供了API接口，可以方便二次開發使用。
Cobbler是較早前的kickstart的升級版，優點是比較容易配置，還自帶web界面比較易于管理。

cobbler部署流程
第一個里程：安裝cobbler
更改yum源
[root@Cobbler ~]# curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
[root@Cobbler ~]# curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
[root@Cobbler ~]# yum -y install cobbler cobbler-web dhcp tftp-server pykickstart httpd python-django
第二個里程：安裝軟件
yum -y install cobbler cobbler-web dhcp tftp-server pykickstart httpd
ps:因為系統默認安裝的django版本太低在，所以需要單獨拿出來安裝
wget https://bootstrap.pypa.io/get-pip.py
python get-pip.py
pip install django==1.8.9
systemctl start cobbler
systemctl start httpd
第三個里程：根據cobbler check命給出的提示一個一個進行修正
修改dhcp地址池
[root@Cobbler ks_mirror]# cat /etc/cobbler/dhcp.template
# ******************************************************************
# Cobbler managed dhcpd.conf file
#
# generated from cobbler dhcp.conf template ($date)
# Do NOT make changes to /etc/dhcpd.conf. Instead, make your changes
# in /etc/cobbler/dhcp.template, as /etc/dhcpd.conf will be
# overwritten.

[root@Cobbler ~]# cobbler check
The following are potential configuration items that you may want to fix:
# 1與2需修改配置文件中的server與next_server，將其改成本機的IP地址即可，不能使用127.0.0.1
1 : The 'server' field in /etc/cobbler/settings must be set to something other tha
r kickstarting features will not work. This should be a resolvable hostname or IPserver as reachable by all machines that will use it.2 : For PXE to be functional, the 'next_server' field in /etc/cobbler/settings mus
mething other than 127.0.0.1, and should match the IP of the boot server on the PX
#將tftp配置文件中的disable=yes改成disable=no
3 : change 'disable' to 'no' in /etc/xinetd.d/tftp
#使用cobbler get-loaders命令即可
4 : Some network boot-loaders are missing from /var/lib/cobbler/loaders, you may r
t-loaders' to download them, or, if you only want to handle x86/x86_64 netbooting,e that you have installed a *recent* version of the syslinux package installed andis message entirely. Files in this directory, should you want to support all archuld include pxelinux.0, menu.c32, elilo.efi, and yaboot. The 'cobbler get-loaders'e easiest way to resolve these requirements.
#將rsyncd服務開啟，將設置成開機啟動
5 : enable and start rsyncd.service with systemctl
#忽略，歷史遺留問題
6 : debmirror package is not installed, it will be required to manage debian deplo
ositories
#修改settings中的默認始初密碼，使用命令chaenssl passwd -1 -salt，然后復制到配置文件中即可
7 : The default password used by the sample templates for newly installed machines
word_crypted in /etc/cobbler/settings) is still set to 'cobbler' and should be chaenssl passwd -1 -salt 'random-phrase-here' 'your-password-here'" to generate new o
#忽略，歷史遺留問題
8 : fencing tools were not found, and are required to use the (optional) power man
es. install cman or fence-agents to use themRestart cobblerd and then run 'cobbler sync' to apply changes.
第四個里程：重啟服務并載入修改好的配置
systemctl restart tftp.socket rsyncd.service cobblerd.service
cobbler sync
第五個里程：使用瀏覽器訪問
https://10.0.0.203/cobbler_web
賬號與密碼：cobller
第六個里程：導入鏡像文件
?
第七個里程：修改內核信息
?
第八個里程：添加自已寫好的KS配置文件
