官网介绍:Cobbleris a Linux installation server that allows for rapid setup of networkinstallation environments. It glues together and automates many associatedLinux tasks so you do not have to hop between many various commands andapplications when deploying new systems, and, in some cases, changing existingones. Cobbler can help with provisioning, managing DNS and DHCP, packageupdates, power management, configuration management orchestration, and muchmore.
运维自动化包括标准化、工具化、Web化、服务化、智能化等几个不同的层级,在一家规模稍大、拥有服务器上千台甚至是几万台的生产环境中,想要真正实现运维自动化,工具化系统安装流程、统一系统安装规范,是其中最不能忽略的重要环节。普通的自动化部署可以采用pxe+dhcp+tftp配合kickstart实现,但是面对多版本、多部署需求的情况下,这种普通的部署方式可能达不到我们的要求;这时候就需要借助cobbler开源自动化部署工具来实现。
Cobbler是一个Linux服务器安装的服务(在经过调整也可以支持网络安装windows),用以自动化批量安装服务器系统,是当前自动化运维环境中不可或缺的工具。该工具使用python开发,小巧轻便(才15k行python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、yum仓库、构造系统ISO镜像。
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)
首先,要自动安装系统的机器,必须支持PXE,无论是有PXE的网卡或者芯片等(目前绝大部分的机器均支持)。
预启动执行环境(Preboot eXecution Environment,PXE,也被称为预执行环境)是让计算机通过网卡独立地使用数据设备(如硬盘)或者安装操作系统。PXE当初是作为Intel的有线管理体系的一部分,Intel和 Systemsoft于1999年9月20日公布其规格(版本2.1)。通过使用像网际协议(IP)、用户数据报协议(UDP)、动态主机设定协定(DHCP)、小型文件传输协议(TFTP)等几种网络协议和全局唯一标识符(GUID)、通用网络驱动接口(UNDI)、通用唯一识别码(UUID)的概念并通过对客户机(通过PXE自检的电脑)固件扩展预设的API来实现目的。PXE 客户机(client)这个术语是指机器在PXE启动过程中的角色。一个PXE 客户机(client)可以是一台服务器、桌面级电脑、笔记本电脑或者其他装有PXE启动代码的机器。
客户机的固件为接受到可用的PXE启动服务器,要在网络中尝试找出PXE重定向服务(DHCP代理)。在分析返回的包后,固件会向合适的启动服务器询问网络自检程序(NBP)的路径,并且通过TFTP协议下载到电脑的内存中,有可能会去校验它,最后执行它。当只有全部的PXE 客户机(client)只使用一个NBP时,全部的PXE 客户机可能会被指定是用BOOTP协议,从而不需要DHCP代理,但是仍然需要TFTP启动服务。
PXE 协议大致上结合了DHCP和TFTP,虽然都有在两者上面有改进。DHCP用于查找合适的启动服务器,TFTP用于下载初始引导程序和附加文件。为了开始一个PXE自检会话,PXE固件广播一个带有明确的PXE选项DHCPDISCOVER包(扩展DHCPDISCOVER)到67/UDP端口(DHCP服务器端口)。PXE选项是PXE固件有PXE能力的鉴定,但是会被一般的DHCP服务忽略。当固件受到从这样的服务受到DHCPOFFER包时,它会通过要求其提供配置信息来自我配置。
当 PXE 重定向服务 (DHCP代理) 收到一个 扩展DHCPDISCOVER 包时,它会通过发送一个带有明确的PXE选项DHCPDISCOVER包到PXE客户机的68/UDP端口 (DHCP 客户机端口)来回答。一个扩展DHCPDISCOVER包主要包含:
一个PXE发现控制领域,以决定是使用多播,广播(网路)或单播来联系PXE启动服务器。
一个列出可用的PXE启动服务器类型的地址表。
一个代表每个一个PXE启动服务器类型的条目单。
一个带有带有提示用户按下哪一个键来看到启动菜单的PXE启动菜单。
一个超过多长时间就启动第一启动菜单的超时数值。
一个DHCP代理服务可能在相同的主机上运行一个标准的DHCP服务器。尽管两个服务不可以共享67/UDP 端口,DHCP代理服务在4011/UDP 端口上运行,要求从客户端来的DHCPDISCOVER 包变成DHCPREQUEST 包。标准DHCP服务在其发送的DHCPOFFER 包中加入特殊的PXE 选项组合,这样PXE客户端知道可以在同一个主机的 4011/UDP 端口找到一个DHCP代理服务。
和一个正在启动系统的启动服务联系必须有一个IP地址(可能来自DHCP服务)。通过多播或单播一个带有特殊的PXE选项的 DHCPREQUEST 包(扩展DHCPREQUEST包)到 4011/UDP端口,或者广播(网路)这种包到 67/UDP端口。这种包包含有PXE启动服务类型和PXE启动层,一个守护进程允许运行多个启动服务类型。 一个扩展 DHCPREQUEST包可能是一个DHCPINFORM包。下面是PXE具体工作原理图,
简单总结一下:
PXE Client发送广播包请求DHCP分配IP地址DHCP;
Server回复请求,给出IP地址以及Boot;
Server的地址PXE下载引导文件执行引导程序;
KickStart是一种无人职守安装方式。KickStart的工作原理是通过记录典型的安装过程中所需人工干预填写的各种参数,并生成一个名为ks.cfg的文件;在其后的安装过程中(不只局限于生成KickStart安装文件的机器)当出现要求填写参数的情况时,安装程序会首先去查找KickStart生成的文件,当找到合适的参数时,就采用找到的参数,当没有找到合适的参数时,才需要安装者手工干预。这样,如果KickStart文件涵盖了安装过程中出现的所有需要填写的参数时,安装者完全可以只告诉安装程序从何处取ks.cfg(注:Cobbler一般使用.ks或.cfg文件)文件,然后去忙自己的事情。等安装完毕,安装程序会根据ks.cfg中设置的重启选项来重启系统,并结束安装。
工作原理大致如下:
cobbler是实现自动化安装操作系统的工具。它解决了PXE安装时的弊端(只能实现单一操作系统的安装)。实际上,cobbler是对PXE二次封装可实现多版本,多环境操作系统安装的高级抽象工具。

再次检查:
[root@Cobbler~]#cobbler check The following are potential configuration items thatyou may want to fix: 1 : The ‘server‘ field in /etc/cobbler/settings mustbe set to something other than localhost, or kickstarting features will notwork. This should be a resolvablehostname or IP for the boot server as reachable by all machines that will useit. 2 : For PXE to be functional, the ‘next_server‘ fieldin /etc/cobbler/settings must be set to something other than 127.0.0.1, andshould match the IP of the boot server on the PXE network. 3 : change ‘disable‘ to ‘no‘ in /etc/xinetd.d/tftp 4 : change ‘disable‘ to ‘no‘ in /etc/xinetd.d/rsync 5 : file /etc/xinetd.d/rsync does not exist 6 : debmirror package is not installed, it will berequired to manage debian deployments and repositories 7 : The default password used by the sample templatesfor 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 touse the (optional) power management features. install cman or fence-agents touse them Restart cobblerd and then run ‘cobbler sync‘ to applychanges.
先备份配置文件:
[root@Cobbler~]#cp /etc/cobbler/settings /etc/cobbler/settings.bak
设置Cobbler服务器IP:
[root@Cobbler~]#sed -i ‘s/server: 127.0.0.1/server: 192.168.10.5/‘/etc/cobbler/settings
设置next_server,作用和kickstart的类似,tftp的ip:
[root@Cobbler~]#sed -i ‘s/next_server: 127.0.0.1/next_server:192.168.10.5/‘ /etc/cobbler/settings
用Cobbler管理DHCP:
[root@Cobbler~]#sed -i ‘s/manage_dhcp:0/manage_dhcp: 1/‘ /etc/cobbler/settings
防止循环装系统,适用于服务器第一启动项是PXE启动:
[root@Cobbler~]#sed -i ‘s/pxe_just_once: 0/pxe_just_once: 1/‘ /etc/cobbler/settings
设置新装系统的默认root密码123456。random-phrase-here为干扰码,可以自行设定:
[root@Cobbler ~]#openssl passwd -1 -salt ‘test‘ ‘123456‘ $1$test$at615QShYKduQlx5z9Zm7/ [root@Cobbler ~]#vim /etc/cobbler/settings default_password_crypted: "$1$test$at615QShYKduQlx5z9Zm7/"
开启rsync,把disable的yes改为no:
[root@Cobbler ~]#vim /etc/xinetd.d/rsync servicersync { disable=no flags =IPv6 socket_type =stream wait =no user =root server =/usr/bin/rsync server_args =--daemon log_on_failure +=USERID } [root@Cobbler~]#/etc/init.d/xinetd restart Stopping xinetd: [FAILED] Starting xinetd: [ OK ]
配置DHCP模板:

配置详解:
