Cobbler-自动化部署神器
前言：
网络安装服务器套件 Cobbler(补鞋匠)从前，我们一直在做装机民工这份很有前途的职业。自打若干年前 Red Hat 推出了 Kickstart，此后我们顿觉身价倍增。不再需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，我们就可以像哈里波特一样，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一般人都能整明白的，没有大专以上学历，通不过英语四级， 根本别想玩转。
**总而言之，这是一份多么有前途，多么有技术含量的工作啊。
**
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，成功降低到初中以下，连补鞋匠都能学会。
对于我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说，不啻为一个晴天霹雳。
竟然让我无法ZB岂有此理！！
笔者QQ：315420700 【让我们共同学习ZB技巧吧】
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，如果你还有问题那说明什么？
请认真看文档做，先全照搬然后再自我发挥
1. Cobbler介绍
Cobbler是一个Linux服务器快速网络安装的服务，而且在经过调整也可以支持网络安装windows。
该工具使用python开发，小巧轻便（才15k行python代码），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，TFTP、RSYNC以及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客户端Koan支持虚拟机安装和操作系统重新安装，使重装系统更便捷。
1)Cobbler可以干啥
使用Cobbler，您无需进行人工干预即可安装机器。Cobbler设置一个PXE引导环境（它还可以使用yaboot支持PowerPC），并 控制与安装相关的所有方面，比如网络引导服务（DHCP和TFTP）与存储库镜像。当希望安装一台新机器时，Cobbler可以：
1）使用一个以前定义的模板来配置DHCP服务（如果启用了管理DHCP）
2）将一个存储库（yum或rsync）建立镜像或解压缩一个媒介，以注册一个新操作系统
3）在DHCP配置文件中为需要安装的机器创建一个条目，并使用指定的参数（IP和MAC）
4）在TFTP服务目录下创建适当的PXE文件
5）重新启动DHCP服务来反应新的更改
6）重新启动机器以开始安装（如果电源管理已启动）
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。当添加一个操作系统（通常通过使用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可以使用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。通过使用模板，就会拥有基本的kickstart模板，然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，并且每台使用该配置文件的机器在machine_name变量中指定其名称。该配置文件的所有机器都使用相同的 kickstart安装且针对domain=mydomain.com进行配置，但每台机器拥有其自己的机器名称。您仍然可以使用kickstart模板 在不同的域中安装其他机器并使用不同的机器名称。
为了协助管理系统，Cobbler可通过fence scripts连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。要重新安装一台机器，可 运行reboot system foo命令，而且Cobbler会使用必要的 和信息来为您运行恰当的fence scripts（比如机器插槽数）。
除了这些特性，还可以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，比如Chef或 Puppet。借助内部系统，你可以指定文件模板，这些模板会依据配置参数进行处理（与kickstart模板的处理方式一样），然后复制到你指定的位 置。如果必须自动将配置文件部署到特定机器，那么此功能很有用
使用koan客户端，Cobbler可从客户端配置虚拟机并重新安装系统。
2.Cobbler各个组件之间关系：
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。每个对象表示一个与另一个实体相关联的实体（该对象指向另一个对象，或者另一个对象指向该对象）。当一个对象指向另一个对象时，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。以下对象类型的定义
Distros（发行版）：表示一个操作系统，它承载了内核和initrd的信息，以及内核参数等其他数据
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他数据
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，无法分为内核和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。因为系统配置的内部是抽象的，所以您可以仅关注想要执行的操作。

注意：
- 虚拟机网卡采用桥接模式，不使用NAT模式，我们会搭建DHCP服务器，在同一局域网多个DHCP服务会有冲突，所以最好把路由器的DHCP服务关闭
我搭建服务只喜欢用桥接模式，就是与众不同，不服？

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全部，但需要配置文件/etc/cobbler/settings中的“manange_dhcp”、“manager_tftpd”、“manager_rsync”、“manager_dns”分别来进行定义，另外，由于各种服务都有着不同的实现方式，如若需要进行自定义，需要通过修改/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，需要在cobblerd和httpd启动的情况下检查
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如下所示：
1、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
2、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，由于这里使用的是同一台机器，所以填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
#由于sed的匹配规则的原因，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
3、修改/etc/xinetd.d/tftp文件中的disable参数修改为 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
4、执行 cobbler get-loaders 命令即可；否则，需要安装syslinux程序包，而后复制/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
5、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 }
6、rsync
7、安装debmirror
[root@cobbler cobbler]# yum install -y debmirror
#安装后再check下会报如下错误
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，但是报错有碍眼睛，遂除之 [root@cobbler cobbler]# vim /etc/debmirror.conf 28 #@dists="sid"; 30 #@arches="i386"; 注释掉这两行，重新check后没有报错了
8、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，这里是自己的密码，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/"
9、安装cman fence-agents
[root@cobbler cobbler]# yum install -y cman ence-agents
10、其他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

1、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
2、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，由于这里使用的是同一台机器，所以填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
#由于sed的匹配规则的原因，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
3、修改/etc/xinetd.d/tftp文件中的disable参数修改为 disable = no
#备份原文件

4、执行 cobbler get-loaders 命令即可；否则，需要安装syslinux程序包，而后复制/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 ***
5、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.

6、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请边做边写博客，务必真实可靠not copy！
8、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，这里是自己的密码，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/"
9、安装cman fence-agents
[root@cobbler02 ~]# yum install -y cman fence-agents
10、其他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

#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，定期同步repo

centos7系列：
******1)不指定详细system模板，让cobbler自己装一台centos7的镜像
#注意上面如果没有指定epel源的是无法装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和其他你指定的东西
[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，但是这里出现了一个问题，双网卡的话，两个网段，现在的路由都是同一个了，所以上不了网了，求高手解决
