Cobbler-自动化部署神器

前言:html

网络安装服务器套件 Cobbler(补鞋匠)从前,咱们一直在作装机民工这份颇有前途的职业。自打若干年前 Red Hat 推出了 Kickstart,此后咱们顿觉身价倍增。再也不须要刻了光盘一台一台地安装 Linux,只要搞定 PXE、DHCP、 TFTP,还有那满屏眼花缭乱不知所云的 Kickstart 脚本,咱们就能够像哈里波特同样,轻点魔棒,瞬间安装上百台服务器。这一堆花里胡哨的东西可不是通常人都能整明白的,没有大专以上学历,通不过英语四级, 根本别想玩转。node

总而言之,这是一份多么有前途,多么有技术含量的工做啊。j_0003.gif

很不幸,Red Hat 最新(Cobbler项目最初在2008年左右发布)发布了网络安装服务器套件 Cobbler(补鞋匠),它已将 Linux 网络安装的技术门槛,从大专以上文化水平,成功下降到初中如下,连补鞋匠都能学会。linux

对于咱们这些在装机领域浸淫多年,经验丰富,老骥伏枥,志在千里的民工兄弟们来讲,不啻为一个晴天霹雳。ios

 

j_0004.gif居然让我没法ZB岂有此理!!git

笔者QQ:315420700 【让咱们共同窗习ZB技巧吧】github

 

 

我又使用最新的centos7.3进行的安装(2017.09.05),全程复制粘贴后,没有任何问题,若是你还有问题那说明什么?

j_0012.gif请认真看文档作,先全照搬而后再自我发挥web

 

1. Cobbler介绍shell

Cobbler是一个Linux服务器快速网络安装的服务,并且在通过调整也能够支持网络安装windows。apache

该工具使用python开发,小巧轻便(才15k行python代码),能够经过网络启动(PXE)的方式来快速安装、重装物理服务器和虚拟机,同时还能够管理DHCP,DNS,TFTP、RSYNC以及yum仓库、构造系统ISO镜像。

Cobbler可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,能够方便二次开发使用。

Cobbler是较早前的kickstart的升级版,优势是比较容易配置,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客户端Koan支持虚拟机安装和操做系统从新安装,使重装系统更便捷。

 

1)Cobbler能够干啥

 

使用Cobbler,您无需进行人工干预便可安装机器。Cobbler设置一个PXE引导环境(它还可使用yaboot支持PowerPC),并 控制与安装相关的全部方面,好比网络引导服务(DHCP和TFTP)与存储库镜像。当但愿安装一台新机器时,Cobbler能够:

1)使用一个之前定义的模板来配置DHCP服务(若是启用了管理DHCP)

2)将一个存储库(yum或rsync)创建镜像或解压缩一个媒介,以注册一个新操做系统

3)在DHCP配置文件中为须要安装的机器建立一个条目,并使用指定的参数(IP和MAC)

4)在TFTP服务目录下建立适当的PXE文件

5)从新启动DHCP服务来反应新的更改

6)从新启动机器以开始安装(若是电源管理已启动)

 

2)Cobbler支持的系统和功能

Cobbler支持众多的发行版:RedHat、Fedora、CentOS、Debian、Ubuntu和SUSE。当添加一个操做系统(一般经过使用ISO文件)时,Cobbler知道如何解压缩合适的文件并调整网络服务,以正确引导机器。

Cobbler可使用kickstart模板。基于Red Hat或 Fedora的系统使用kickstart文件来自动化安装流程。经过使用模板,就会拥有基本的kickstart模板,而后定义如何针对一种配置文件或 机器配置而替换其中的变量。例如,一个模板可能包含两个变量$domain和$machine_name.在Cobbler配置中,一个配置文件指定 domain=mydomain.com,而且每台使用该配置文件的机器在machine_name变量中指定其名称。该配置文件的全部机器都使用相同的 kickstart安装且针对domain=mydomain.com进行配置,但每台机器拥有其本身的机器名称。您仍然可使用kickstart模板 在不一样的域中安装其余机器并使用不一样的机器名称。

为了协助管理系统,Cobbler可经过fence scripts链接到各个电源管理环境。Cobbler支持apc_snmp、bladecenter、bullpap、drac、 ether_wake、ilo、integrity、ipmilan、ipmitool、lpar、rsa、virsh和wti。要从新安装一台机器,可 运行reboot system foo命令,并且Cobbler会使用必要的 和信息来为您运行恰当的fence scripts(好比机器插槽数)。

除了这些特性,还可使用一个配置管理系统(CMS)。你有两种选择:该工具内的一个内部系统,或者现成的外部CMS,好比Chef或 Puppet。借助内部系统,你能够指定文件模板,这些模板会依据配置参数进行处理(与kickstart模板的处理方式同样),而后复制到你指定的位 置。若是必须自动将配置文件部署到特定机器,那么此功能颇有用

使用koan客户端,Cobbler可从客户端配置虚拟机并从新安装系统。

2.Cobbler各个组件之间关系:

wKioL1dCyxTAinKaAAH0I6yzrL8642.jpg

 

主要目的配置网络接口:

Cobbler的配置结构基于一组注册的对象。每一个对象表示一个与另外一个实体相关联的实体(该对象指向另外一个对象,或者另外一个对象指向该对象)。当一个对象指向另外一个对象时,它就继承了被指向对象的数据,并可覆盖或添加更多特定信息。如下对象类型的定义

Distros(发行版):表示一个操做系统,它承载了内核和initrd的信息,以及内核参数等其余数据

Profile(配置文件):包含一个发行版、一个kickstart文件以及可能的存储库,还包含更多特定的内核参数等其余数据

Systems(系统):表示要配给的额机器。它包含一个配置文件或一个景象,还包含IP和MAC地址、电源管理(地址、凭据、类型)、(网卡绑定、设置valn等)

Repository(镜像):保存一个yum或rsync存储库的镜像信息

Image(存储库):可替换一个包含不属于此类比的额文件的发行版对象(例如,没法分为内核和initrd的对象)。

基于注册的对象以及各个对象之间的关联,Cobbler知道如何更改文件系统以反应具体配置。由于系统配置的内部是抽象的,因此您能够仅关注想要执行的操做。

注意:

  • 虚拟机网卡采用桥接模式,不使用NAT模式,咱们会搭建DHCP服务器,在同一局域网多个DHCP服务会有冲突,因此最好把路由器的DHCP服务关闭t_0015.gif我搭建服务只喜欢用桥接模式,就是不同凡响,不服?

 

4.安装Cobbler

centos7系列:

[root@cobbler02 ~]# yum install cobbler cobbler-web pykickstart httpd dhcp tftp-server -y cobbler #cobbler程序包 cobbler-web #cobbler的web服务包 pykickstart #cobbler检查kickstart语法错误 httpd #Apache web服务 dhcp #dhcp服务 tftp-server #tftp服务

 

5. 检测Cobbler

cobbler的运行依赖于dhcp、tftp、rsync及dns服务,其中dhcp可由dhcpd(isc)提供,也可由dnsmasq提供;tftp可由tftp-server程序包提供,也可由cobbler功能提供,rsync有rsync程序包提供,dns可由bind提供,也可由dnsmasq提供

cobbler可自行管理这些服务中的部分甚至是所有,但须要配置文件/etc/cobbler/settings中的“manange_dhcp”、“manager_tftpd”、“manager_rsync”、“manager_dns”分别来进行定义,另外,因为各类服务都有着不一样的实现方式,如若须要进行自定义,须要经过修改/etc/cobbler/modules.conf配置文件中各服务的模块参数的值来实现。

检查配置文件,须要在cobblerd和httpd启动的状况下检查

 

centos6系列:

[root@cobbler cobbler]# cobbler check #检查cobbler配置存在的问题,逐一解决 The following are potential configuration items that you may want to fix: 1 : The 'server' field in /etc/cobbler/settings must be set to something other than localhost, or kickstarting features will not work. This should be a resolvable hostname or IP for the boot server as reachable by all machines that will use it. 2 : For PXE to be functional, the 'next_server' field in /etc/cobbler/settings must be set to something other than 127.0.0.1, and should match the IP of the boot server on the PXE network. 3 : change 'disable' to 'no' in /etc/xinetd.d/tftp 4 : some network boot-loaders are missing from /var/lib/cobbler/loaders, you may run 'cobbler get-loaders' to download them, or, 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, elilo.efi, and yaboot. The 'cobbler get-loaders' command is the easiest way to resolve these requirements. 5 : change 'disable' to 'no' in /etc/xinetd.d/rsync 6 : file /etc/xinetd.d/rsync does not exist 7 : debmirror package is not installed, it will be required to manage debian deployments and repositories 8 : The default password used by the sample templates for 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 9 : 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.

 

如上各问题的解决方法以下所示:

一、修改/etc/cobbler/settings文件中的server参数的值为提供cobbler服务的主机相应的IP地址或主机名,如server: 192.168.31.71;
#备份原文件 [root@cobbler cobbler]# cp /etc/cobbler/settings{,.ori} # server,Cobbler服务器的IP,修改384行server: 127.0.0.1 [root@cobbler cobbler]# sed -i 's/server: 127.0.0.1/server: 192.168.31.71/' /etc/cobbler/settings
二、修改/etc/cobbler/settings文件中的next_server参数的值为提供PXE服务的主机相应的IP地址,如next_server: 192.168.31.71;
# server,pxe服务器的IP,因为这里使用的是同一台机器,因此填Cobbler服务器的IP,修改272行next_server: 127.0.0.1 [root@cobbler cobbler]# sed -i 's/next_server: 127.0.0.1/next_server: 192.168.31.71/' /etc/cobbler/settings #因为sed的匹配规则的缘由,上一步就已经把这里给修改了,检查下 [root@cobbler cobbler]# grep "server: 192.168.31.71" settings next_server: 192.168.31.71 server: 192.168.31.71
三、修改/etc/xinetd.d/tftp文件中的disable参数修改成 disable = no #备份原文件 [root@cobbler cobbler]# cp /etc/xinetd.d/tftp{,.ori} #修改替换 [root@cobbler cobbler]# sed -i 's/disable.*= yes/disable = no/g' /etc/xinetd.d/tftp
四、执行 cobbler get-loaders 命令便可;不然,须要安装syslinux程序包,然后复制/usr/share/syslinux/{pxelinux.0,memu.c32}等文件至/var/lib/cobbler/loaders/目录中; [root@cobbler cobbler]# cobbler get-loaders task started: 2016-05-23_230908_get_loaders task started (id=Download Bootloader Content, time=Mon May 23 23:09:08 2016) downloading http://cobbler.github.io/loaders/README to /var/lib/cobbler/loaders/README downloading http://cobbler.github.io/loaders/COPYING.elilo to /var/lib/cobbler/loaders/COPYING.elilo downloading http://cobbler.github.io/loaders/COPYING.yaboot to /var/lib/cobbler/loaders/COPYING.yaboot downloading http://cobbler.github.io/loaders/COPYING.syslinux to /var/lib/cobbler/loaders/COPYING.syslinux downloading http://cobbler.github.io/loaders/elilo-3.8-ia64.efi to /var/lib/cobbler/loaders/elilo-ia64.efi downloading http://cobbler.github.io/loaders/yaboot-1.3.17 to /var/lib/cobbler/loaders/yaboot downloading http://cobbler.github.io/loaders/pxelinux.0-3.86 to /var/lib/cobbler/loaders/pxelinux.0 downloading http://cobbler.github.io/loaders/menu.c32-3.86 to /var/lib/cobbler/loaders/menu.c32 downloading http://cobbler.github.io/loaders/grub-0.97-x86.efi to /var/lib/cobbler/loaders/grub-x86.efi downloading http://cobbler.github.io/loaders/grub-0.97-x86_64.efi to /var/lib/cobbler/loaders/grub-x86_64.efi
五、修改rsync配置文件;
[root@cobbler xinetd.d]# sed -i s/"disable.*= yes"/"disable = no"/g /etc/xinetd.d/rsync [root@cobbler xinetd.d]# cat /etc/xinetd.d/rsync # default: off # description: The rsync server is a good addition to an ftp server, as it \ # allows crc checksumming etc. service rsync { disable = no flags = IPv6 socket_type = stream wait = no user = root server = /usr/bin/rsync server_args = --daemon log_on_failure += USERID }
六、rsync
七、安装debmirror 
[root@cobbler cobbler]# yum install -y debmirror #安装后再check下会报以下错误 3 : comment out 'dists' on /etc/debmirror.conf for proper debian support4 : comment out 'arches' on /etc/debmirror.conf for proper debian support #修改配置文件来征服报错,其实不碍事,可是报错有碍眼睛,遂除之 [root@cobbler cobbler]# vim /etc/debmirror.conf 28 #@dists="sid"; 30 #@arches="i386"; 注释掉这两行,从新check后没有报错了
八、生成密码来取代默认的密码,更安全
#try: "openssl passwd -1 -salt 'random-phrase-here' 'your-password-here'" to generate new one #根据提示your-password-here,这里是本身的密码,random-phrase-here,这里是随机的干扰码 [root@cobbler cobbler]# openssl passwd -1 -salt 'renjunjie' '123456' $1$renjunji$G7LpR5255qFguHrw7E0KP/ [root@cobbler cobbler]# sed -i s/'default_password_crypted:.*'/'default_password_crypted: "$1$renjunji$G7LpR5255qFguHrw7E0KP\/"'/g /etc/cobbler/settings [root@cobbler cobbler]# grep -n default_pass /etc/cobbler/settings 101:default_password_crypted: "$1$renjunji$G7LpR5255qFguHrw7E0KP/"
九、安装cman fence-agents
[root@cobbler cobbler]# yum install -y cman ence-agents
十、其余一些没有提示报错的小修改
# 用cobbler管理DHCP,修改242行manage_dhcp: 0 [root@cobbler cobbler]# sed -i 's/manage_dhcp: 0/manage_dhcp: 1/g' /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,修改292行pxe_just_once: 0 [root@cobbler cobbler]# sed -i 's/pxe_just_once: 0/pxe_just_once: 1/' /etc/cobbler/settings
#修改完后重启服务再进行一次检测,发现剩下这两个报错,请往下走 [root@cobbler cobbler]# /etc/init.d/httpd restart Stopping httpd: [ OK ] Starting httpd: [ OK ] [root@cobbler cobbler]# /etc/init.d/xinetd restart Stopping xinetd: [ OK ] Starting xinetd: [ OK ] [root@cobbler cobbler]# /etc/init.d/cobblerd restart Stopping cobbler daemon: [ OK ] Starting cobbler daemon: [ OK ] [root@cobbler cobbler]# check checkmodule checkpolicy [root@cobbler cobbler]# cobbler check The following are potential configuration items that you may want to fix: 1 : service dhcpd is not running 2 : file /etc/xinetd.d/rsync does not exist Restart cobblerd and then run 'cobbler sync' to apply changes.

一、修改/etc/cobbler/settings文件中的server参数的值为提供cobbler服务的主机相应的IP地址或主机名,如server: 192.168.31.73;
#备份原文件 [root@cobbler02 ~]# cp /etc/cobbler/settings{,.ori} # server,Cobbler服务器的IP,修改384行server: 127.0.0.1 [root@cobbler02 ~]# sed -i 's/server: 127.0.0.1/server: 192.168.31.73/' /etc/cobbler/settings
二、修改/etc/cobbler/settings文件中的next_server参数的值为提供PXE服务的主机相应的IP地址,如next_server: 192.168.31.73;
# server,pxe服务器的IP,因为这里使用的是同一台机器,因此填Cobbler服务器的IP,修改272行next_server: 127.0.0.1 [root@cobbler02 ~]# sed -i 's/next_server: 127.0.0.1/next_server: 192.168.31.73/' /etc/cobbler/settings #因为sed的匹配规则的缘由,上一步就已经把这里给修改了,检查下 [root@cobbler02 ~]# grep "server: 192.168.31.73" settings next_server: 192.168.31.713 server: 192.168.31.73
三、修改/etc/xinetd.d/tftp文件中的disable参数修改成 disable = no #备份原文件 [root@cobbler02 ~]# cp /etc/xinetd.d/tftp{,.ori} #修改替换 [root@cobbler02 ~r]# sed -i 's/disable.*= yes/disable = no/g' /etc/xinetd.d/tftp
四、执行 cobbler get-loaders 命令便可;不然,须要安装syslinux程序包,然后复制/usr/share/syslinux/{pxelinux.0,memu.c32}等文件至/var/lib/cobbler/loaders/目录中; [root@cobbler02 ~]# cobbler get-loaders task started: 2016-05-30_082337_get_loaders task started (id=Download Bootloader Content, time=Mon May 30 08:23:37 2016) downloading http://cobbler.github.io/loaders/README to /var/lib/cobbler/loaders/README downloading http://cobbler.github.io/loaders/COPYING.elilo to /var/lib/cobbler/loaders/COPYING.elilo downloading http://cobbler.github.io/loaders/COPYING.yaboot to /var/lib/cobbler/loaders/COPYING.yaboot downloading http://cobbler.github.io/loaders/COPYING.syslinux to /var/lib/cobbler/loaders/COPYING.syslinux downloading http://cobbler.github.io/loaders/elilo-3.8-ia64.efi to /var/lib/cobbler/loaders/elilo-ia64.efi downloading http://cobbler.github.io/loaders/yaboot-1.3.17 to /var/lib/cobbler/loaders/yaboot downloading http://cobbler.github.io/loaders/pxelinux.0-3.86 to /var/lib/cobbler/loaders/pxelinux.0 downloading http://cobbler.github.io/loaders/menu.c32-3.86 to /var/lib/cobbler/loaders/menu.c32 downloading http://cobbler.github.io/loaders/grub-0.97-x86.efi to /var/lib/cobbler/loaders/grub-x86.efi downloading http://cobbler.github.io/loaders/grub-0.97-x86_64.efi to /var/lib/cobbler/loaders/grub-x86_64.efi *** TASK COMPLETE ***
五、启动rsyncd服务
[root@cobbler02 ~]# systemctl status rsyncd #检查rsyncd服务的状态,发现是关闭的 ● rsyncd.service - fast remote file copy program daemon Loaded: loaded (/usr/lib/systemd/system/rsyncd.service; disabled; vendor preset: disabled) Active: inactive (dead) [root@cobbler02 ~]# systemctl enable rsyncd #开启rsync的服务开机自启动 Created symlink from /etc/systemd/system/multi-user.target.wants/rsyncd.service to /usr/lib/systemd/system/rsyncd.service. [root@cobbler02 ~]# systemctl status rsyncd #检查rsyncd服务的状态 ● rsyncd.service - fast remote file copy program daemon Loaded: loaded (/usr/lib/systemd/system/rsyncd.service; enabled; vendor preset: disabled) Active: inactive (dead) [root@cobbler02 ~]# systemctl start rsyncd #开启rsync的服务 [root@cobbler02 ~]# systemctl status rsyncd #再次检查rsyncd服务的状态 ● rsyncd.service - fast remote file copy program daemon Loaded: loaded (/usr/lib/systemd/system/rsyncd.service; enabled; vendor preset: disabled) Active: active (running) since Mon 2016-05-30 08:27:12 CST; 3s ago Main PID: 2455 (rsync) CGroup: /system.slice/rsyncd.service └─2455 /usr/bin/rsync --daemon --no-detach May 30 08:27:12 cobbler02 systemd[1]: Started fast remote file copy program daemon.

六、安装debmirror
[root@cobbler02 ~]# yum install debmirror Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * epel: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com No package debmirror available. Error: Nothing to do #这个是提供给debian的管理用的,centos7我没找到这个包,博客中写centos7能yum装出来的人,麻烦不要把centos6那里直接复制粘贴过来不加考证o(╯□╰)o请边作边写博客,务必真实可靠not copy!
八、生成密码来取代默认的密码,更安全
#try: "openssl passwd -1 -salt 'random-phrase-here' 'your-password-here'" to generate new one #根据提示your-password-here,这里是本身的密码,random-phrase-here,这里是随机的干扰码 [root@cobbler02 ~]# openssl passwd -1 -salt 'renjunjie' '123456' $1$renjunji$G7LpR5255qFguHrw7E0KP/ [root@cobbler02 ~]# sed -i s/'default_password_crypted:.*'/'default_password_crypted: "$1$renjunji$G7LpR5255qFguHrw7E0KP\/"'/g /etc/cobbler/settings [root@cobbler02 ~]# grep -n default_pass /etc/cobbler/settings 101:default_password_crypted: "$1$renjunji$G7LpR5255qFguHrw7E0KP/"
九、安装cman fence-agents
[root@cobbler02 ~]# yum install -y cman fence-agents
十、其余一些没有提示报错的小修改
# 用cobbler管理DHCP,修改242行manage_dhcp: 0 [root@cobbler02 ~]# sed -i 's/manage_dhcp: 0/manage_dhcp: 1/g' /etc/cobbler/settings [root@cobbler02 ~]# grep -n manage_dhcp /etc/cobbler/settings 242:manage_dhcp: 1 269:# if using cobbler with manage_dhcp, put the IP address 355:# Note that if manage_dhcp and manage_dns are disabled, the respective # 防止循环装系统,适用于服务器第一启动项是PXE启动,修改292行pxe_just_once: 0 [root@cobbler02 ~]# sed -i 's/pxe_just_once: 0/pxe_just_once: 1/' /etc/cobbler/settings [root@cobbler02 ~]# grep -n pxe_just_once /etc/cobbler/settings 292:pxe_just_once: 1 [root@cobbler02 ~]#
#修改完后重启服务再进行一次检测,发现这个报错,请往下走 [root@cobbler02 ~]# systemctl restart cobblerd.service [root@cobbler02 ~]# cobbler check 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 Restart cobblerd and then run 'cobbler sync' to apply changes. [root@cobbler02 ~]# yum install -y debmirror #再次安装centos7就是没得,求适用于centos7的rpm包或者适用于centos7的编译源码包 Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * epel: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com No package debmirror available. Error: Nothing to do

6.2配置ks.cfg(使用centos7的镜像的时候,注意下方的ks.cfg要在安装包那里删除掉@server-policy,这玩意在7没有的,不要问我为啥会特地在这里写,由于爱过!!!!!!被伤过!!!!!)

[root@cobbler ks_mirror]# cd /var/lib/cobbler/kickstarts/ [root@cobbler kickstarts]# ls default.ks esxi5-ks.cfg legacy.ks sample_autoyast.xml sample_esx4.ks sample_esxi5.ks sample_old.seed esxi4-ks.cfg install_profiles pxerescue.ks sample_end.ks(默认使用的ks文件) sample_esxi4.ks sample.ks sample.seed [root@cobbler kickstarts]# vim CentOS-6.6-x86_64.cfg #修改为如下内容 [root@cobbler kickstarts]# cat CentOS-6.6-x86_64.cfg # kickstart template for Fedora 8 and later. # (includes %end blocks) # do not use with earlier distros #platform=x86, AMD64, or Intel EM64T # System authorization information #auth --useshadow --enablemd5 authconfig --enableshadow --passalgo=sha512 # System bootloader configuration bootloader --location=mbr --driveorder=sda --append="nomodeset crashkernel=auto rhgb quiet" # Partition clearing information clearpart --all --initlabel # Use text mode install text # Firewall configuration firewall --disabled # Run the Setup Agent on first boot firstboot --disable # System keyboard keyboard us # System language lang en_US # Use network installation url --url=$tree # If any cobbler repo definitions were referenced in the kickstart profile, include them here. $yum_repo_stanza # Network information $SNIPPET('network_config') # Reboot after installation reboot logging --level=info #Root password rootpw --iscrypted $default_password_crypted # SELinux configuration selinux --disabled # Do not configure the X Window System skipx # System timezone timezone Asia/Shanghai # Install OS instead of upgrade install # Clear the Master Boot Record zerombr # Allow anaconda to partition the system as needed #autopart part /boot --fstype=ext4 --asprimary --size=200 part swap --asprimary --size=1024 part / --fstype=ext4 --grow --asprimary --size=200 %pre $SNIPPET('log_ks_pre') $SNIPPET('kickstart_start') $SNIPPET('pre_install_network_config') # Enable installation monitoring $SNIPPET('pre_anamon') %end %packages @base @compat-libraries @core @debugging @development @dial-up @hardware-monitoring @performance @server-policy sgpio device-mapper-persistent-data systemtap-client tree lrzsz telnet nmap dos2unix %end %post --nochroot $SNIPPET('log_ks_post_nochroot') %end %post $SNIPPET('log_ks_post') # Start yum configuration $yum_config_stanza # End yum configuration $SNIPPET('post_install_kernel_options') $SNIPPET('post_install_network_config') $SNIPPET('func_register_if_enabled') $SNIPPET('download_config_files') $SNIPPET('koan_environment') $SNIPPET('redhat_register') $SNIPPET('cobbler_register') # Enable post-install boot notification $SNIPPET('post_anamon') # Start final steps $SNIPPET('kickstart_done') # End final steps %end # 在第一次导入系统镜像后,Cobbler会给镜像指定一个默认的kickstart自动安装文件在/var/lib/cobbler/kickstarts下的sample_end.ks。 [root@cobbler kickstarts]# cobbler list distros: CentOS-6.6-x86_64 profiles: CentOS-6.6-x86_64 systems: repos: images: mgmtclasses: packages: files: # 查看安装镜像文件信息 [root@cobbler kickstarts]# cobbler distro report --name=CentOS-6.6-x86_64 Name : CentOS-6.6-x86_64 Architecture : x86_64 TFTP Boot Files : {} Breed : redhat Comment : Fetchable Files : {} Initrd : /var/www/cobbler/ks_mirror/CentOS-6.6-x86_64/images/pxeboot/initrd.img Kernel : /var/www/cobbler/ks_mirror/CentOS-6.6-x86_64/images/pxeboot/vmlinuz Kernel Options : {} Kernel Options (Post Install) : {} Kickstart Metadata : {'tree': 'http://@@http_server@@/cblr/links/CentOS-6.6-x86_64'} Management Classes : [] OS Version : rhel6 Owners : ['admin'] Red Hat Management Key : <<inherit>> Red Hat Management Server : <<inherit>> Template Files : {} # 查看全部的profile设置 cobbler profile report # 查看指定的profile设置 cobbler profile report --name=CentOS-6.6-x86_64 [root@cobbler kickstarts]# cobbler profile report Name : CentOS-6.6-x86_64 TFTP Boot Files : {} Comment : DHCP Tag : default Distribution : CentOS-6.6-x86_64 Enable gPXE?

这里是若是方向键不选择第二项就没法装机,不算自动化,咱们须要进行手动指定才能够彻底自动化

定制化安装

kickstart实现某台服务器使用指定ks文件可能比较复杂,可是Cobbler就很简单了,区分一台服务器的最简单的方法就是物理MAC地址。

VMware查看物理MAC地址

添加repos源

1.添加repo源
#举个栗子,centos7.2版本的openstack的repo源 [root@cobbler02 ~]# cobbler repo add --name=centos7.2-openstack-mitaka --mirror=http://mirrors.aliyun.com/centos/7.2.1511/cloud/x86_64/openstack-mitaka/ --arch=x86_64 --breed=yum #添加repo源,举个栗子,centos7版本的epel源 [root@cobbler02 ~]# cobbler repo add --name=centos7-x86_64-epel --mirror=http://mirrors.aliyun.com/epel/7/x86_64/ --arch=x86_64 --breed=yum 2.同步repo [root@cobbler02 ~]# cobbler reposync 3.添加repo到对应的profile cobbler profile edit --name=Centos-7-x86_64 --repos= 4.修改kickstart文件。添加。(些到%post %end中间) %post systemctl disable postfix.service $yum_config_stanza %end 5.添加定时任务,按期同步repo

客户机重装系统教程:1

centos7系列:

1)不指定详细system模板,让cobbler本身装一台centos7的镜像

#注意上面若是没有指定epel源的是没法装koan包的 #执行这个命令:wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo [root@zabbix ~]# yum install -y koan #指定cobbler的服务器 [root@zabbix ~]# koan --server=192.168.31.73 --list=profiles - looking for Cobbler at http://192.168.31.73:80/cobbler_api CentOS-7.2-x86_64 #指定从哪一个镜像进行安装 [root@zabbix ~]# koan --replace-self --server=192.168.31.73 --profile=CentOS-7.2-x86_64 - looking for Cobbler at http://192.168.31.73:80/cobbler_api - reading URL: http://192.168.31.73/cblr/svc/op/ks/profile/CentOS-7.2-x86_64 install_tree: http://192.168.31.73/cblr/links/CentOS-7.2-x86_64 downloading initrd initrd.img to /boot/initrd.img_koan url=http://192.168.31.73/cobbler/images/CentOS-7.2-x86_64/initrd.img - reading URL: http://192.168.31.73/cobbler/images/CentOS-7.2-x86_64/initrd.img downloading kernel vmlinuz to /boot/vmlinuz_koan url=http://192.168.31.73/cobbler/images/CentOS-7.2-x86_64/vmlinuz - reading URL: http://192.168.31.73/cobbler/images/CentOS-7.2-x86_64/vmlinuz - ['/sbin/grubby', '--add-kernel', '/boot/vmlinuz_koan', '--initrd', '/boot/initrd.img_koan', '--args', '"ksdevice=link lang= text net.ifnames=0 ks=http://192.168.31.73/cblr/svc/op/ks/profile/CentOS-7.2-x86_64 biosdevname=0 kssendmac "', '--copy-default', '--make-default', '--title=kick1464687061'] - ['/sbin/grubby', '--update-kernel', '/boot/vmlinuz_koan', '--remove-args=root'] - reboot to apply changes #重启系统 [root@zabbix ~]# reboot

2)指定设定好的系统配置,让系统生成一个指定的mac地址绑定的ip和其余你指定的东西

[root@zabbix ~]# yum install -y koan #指定cobbler的服务器选择system模板 [root@MiWiFi-R2D-srv ~]# koan --server=192.168.31.73 --list=system - looking for Cobbler at http://192.168.31.73:80/cobbler_api koan does not know how [root@MiWiFi-R2D-srv ~]# koan --replace-self --server=192.168.31.73 --system=zabbix02 - looking for Cobbler at http://192.168.31.73:80/cobbler_api - reading URL: http://192.168.31.73/cblr/svc/op/ks/system/zabbix02 install_tree: http://192.168.31.73/cblr/links/CentOS-7.2-x86_64 downloading initrd initrd.img to /boot/initrd.img_koan url=http://192.168.31.73/cobbler/images/CentOS-7.2-x86_64/initrd.img - reading URL: http://192.168.31.73/cobbler/images/CentOS-7.2-x86_64/initrd.img downloading kernel vmlinuz to /boot/vmlinuz_koan url=http://192.168.31.73/cobbler/images/CentOS-7.2-x86_64/vmlinuz - reading URL: http://192.168.31.73/cobbler/images/CentOS-7.2-x86_64/vmlinuz - ['/sbin/grubby', '--add-kernel', '/boot/vmlinuz_koan', '--initrd', '/boot/initrd.img_koan', '--args', '"ksdevice=link lang= text net.ifnames=0 ks=http://192.168.31.73/cblr/svc/op/ks/system/zabbix02 biosdevname=0 kssendmac "', '--copy-default', '--make-default', '--title=kick1464688081'] - ['/sbin/grubby', '--update-kernel', '/boot/vmlinuz_koan', '--remove-args=root'] - reboot to apply changes to list that [root@MiWiFi-R2D-srv ~]# reboot

已经按照指定的system配置安装好了,可是这里出现了一个问题,双网卡的话,两个网段,如今的路由都是同一个了,因此上不了网了,求高手解决
