一、Cobbler介绍

1.1 关于Cobbler

Cobbler是一个快速网络安装linux和windows的服务，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、以及yum仓库、构造系统ISO镜像。

Cobbler支持命令行管理，web界面管理，还提供了API接口，可以方便二次开发使用。

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。

Cobbler提供以下服务集成：

* PXE服务支持

* DHCP服务管理

* DNS服务管理

* 电源管理

* Kickstart服务支持

* yum仓库管理

1.2 系统版本支持

Cobbler最初是支持系统版本Fedora, Red Hat和衍生版本，如CentOS 和Scientific Linux.现在对Debian 和Ubuntu SuSE支持也相当强。还支持FreeBSD、ESXI等。

koan 在Fedora, Red Hat Enterprise Linux, or CentOS工作正常，其他Linux版本应该也不错。

Cobbler工作流程：

二、安装Cobbler

2.1 安装EPEL源

默认的光盘中没有cobbler软件，必须在yum仓库中设置第三方的软件源，才能安装cobbler等软件。这里用的epel软件源

什么是epel

EPEL(http://fedoraproject.org/wiki/EPEL) 是由 Fedora 社区打造，为 RHEL 及衍生发行版如 CentOS、Scientific Linux 等提供高质量软件包的项目。

CentOS 5 i386:

rpm -ivh http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm

CentOS 5 x86_64

rpm -ivh http://dl.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm

CentOS 6 i386:

rpm -ivh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-7.noarch.rpm

CentOS 6 x86_64:

rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-7.noarch.rpm

2.2 yum安装cobbler

yum -y install cobbler httpd rsync tftp-server xinetd dhcp python-ctypes

2.3 配置Cobbler

sed -i 's/next_server: 127.0.0.1/next_server: 192.168.5.101/g' /etc/cobbler/settings

sed -i 's/server: 127.0.0.1/server: 192.168.5.101/g' /etc/cobbler/settings sed -i 's/manage_dhcp: 0/manage_dhcp: 1/g' /etc/cobbler/settings

sed -i 's/manage_rsync: 0/manage_rsync: 1/g' /etc/cobbler/settings

/etc/cobbler/settings #Cobbler主配置文件

配置前后内容对比

diff /etc/cobbler/settings /etc/cobbler/settings_2013-10-17

218c218

< manage_dhcp: 1 #启用cobbler管理DHCP功能

---

> manage_dhcp: 0

237c237

< manage_rsync: 1 #启用cobbler管理rsync功能

---

> manage_rsync: 0

248c248

< next_server: 192.168.5.101 # DHCP服务地址

---

> next_server: 127.0.0.1

360c360

< server: 192.168.5.101 # cobbler服务地址

---

> server: 127.0.0.1

2.4 检查、关闭SELinux、iptables

sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

setenforce 0

chkconfig ip6tables off

chkconfig iptables off

/etc/init.d/ip6tables stop

/etc/init.d/iptables stop

2.5 配置tftp、rsync

设置 'disable' 为 'no'

sed -i '/disable/c\\tdisable\t\t\t= no' /etc/xinetd.d/tftp

sed -i 's/\=\ yes/\=\ no/g' /etc/xinetd.d/rsync

2.6 启用wsgi模块

sed -i 's@#LoadModule@LoadModule@g' /etc/httpd/conf.d/wsgi.conf

2.7 生成Cobbler安装系统root初始密码

这里生成密钥和配置默认密钥，ks文件引用

openssl passwd -1 -salt 'random-phrase-here' '123456'

$1$random-p$mzxQ/Sx848sXgvfwJCoZM0

加入cobbler配置

vim /etc/cobbler/settings

grep default_password_crypted /etc/cobbler/settings

default_password_crypted: "$1$random-p$mzxQ/Sx848sXgvfwJCoZM0"

2.8 配置DHCP

cp /etc/cobbler/dhcp.template /etc/cobbler/dhcp.template.$(date +%F) #备份

vim /etc/cobbler/dhcp.template

ddns-update-style interim;

allow booting;

allow bootp;

ignore client-updates;

set vendorclass = option vendor-class-identifier;

subnet 192.168.5.0 netmask 255.255.255.0 {

option routers 192.168.5.1;

option domain-name-servers 202.106.0.20;

option subnet-mask 255.255.255.0;

range dynamic-bootp 192.168.5.180 192.168.5.200;

filename "/pxelinux.0";

default-lease-time 21600;

max-lease-time 43200;

next-server $next_server;

}

2.9 配置相关服务开机自启动

/sbin/service httpd start

/sbin/service dhcpd start

/sbin/service xinetd start

/sbin/service cobblerd start

/sbin/chkconfig httpd on

/sbin/chkconfig dhcpd on

/sbin/chkconfig xinetd on

/sbin/chkconfig tftp on

/sbin/chkconfig cobblerd on

2.10 下载引导操作系统文件

cobbler get-loaders

2.11 配置debmiror

yum -y install debmirror

修改 /etc/debmirror.conf 配置文件，注释掉 @dists 和 @arches 两行

sed -i 's|@dists=.*|#@dists=|' /etc/debmirror.conf

sed -i 's|@arches=.*|#@arches=|' /etc/debmirror.conf

2.12 检查Cobbler 配置

cobbler check

configuration problems found. All systems go. #出现此提示即正常

cobblerd does not appear to be running/accessible #此提示是因为cobbler服务没启动

cobbler check出现的相关报错处理看下面步骤

2.13 同步配置

cobbler sync

列出详细信息可以使用cobbler report

3.6.6 比对大小，确保数据的完整性

du -sh /var/www/cobbler/ks_mirror/centos5.8-x86_64/

4.1G /var/www/cobbler/ks_mirror/centos5.8-x86_64/

du -sh /var/os/Linux/Centos/x86_64/Centos5.8/dvd/

4.3G /var/os/Linux/Centos/x86_64/Centos5.8/dvd/

3.6.7 CentOS6.3、6.4导入过程

CentOS6.3

mount -o loop /var/iso/Linux/Centos/x86_64/CentOS-6.3-x86_64-bin-DVD1.iso /var/os/Linux/Centos/x86_64/Centos6.3/dvd/

cobbler import --path=/var/os/Linux/Centos/x86_64/Centos6.3/dvd/ --name=centos6.3 --arch=x86_64

CentOS6.4

mount -o loop /var/iso/Linux/Centos/x86_64/CentOS-6.4-x86_64-bin-DVD1.iso /var/os/Linux/Centos/x86_64/Centos6.4/dvd/

cobbler import --path=/var/os/Linux/Centos/x86_64/Centos6.4/dvd/ --name=centos6.4 --arch=x86_64

3.7 删除导入的系统

cobbler profile find --distro=centos6.3-x64-x86_64 #查看配置是否存在

centos6.3-x64-x86_64

cobbler profile remove --name=centos6.3-x64-x86_64 #删除配置文件

cobbler distro remove --name=centos6.3-x64-x86_64 #删除distro

cobbler profile find --distro=centos6.3-x64-x86_64 #再查看配置已无

3.8 自定义ks

更改kickstart文件，可为http等，具体cobbler --help查看，这里采用自定制ks文件

ks目录位置

/var/lib/cobbler/kickstarts/

默认的ks位置

/var/lib/cobbler/kickstarts/sample.ks

更改指定系统版本对应的ks配置文件

cobbler profile edit --name=centos5.8-x86_64 --kickstart=/var/lib/cobbler/kickstarts/centos5u8-x64.cfg

cobbler profile edit --name=centos6.3-x86_64 --kickstart=/var/lib/cobbler/kickstarts/centos6u3-x64.cfg

cobbler profile edit --name=centos6.4-x86_64 --kickstart=/var/lib/cobbler/kickstarts/centos6u4-x64.cfg

3.9 配置信息查看

cobbler report

3.10 系统版本列表

cobbler distro list

3.11 同步Cobbler配置

建议先执行cobbler check进行配置检查再执行cobbler sync，修改cobbler配置后都需要执行此步骤

3.14 添加指定客户机系统配置到Cobbler

3.14.1 指定一个网段使用特定的装机配置

cobbler system add --name=network --ip=172.17.188.0/16 --profile=centos5.8-x86_64

3.14.2 添加一个指定服务器的装机配置

指定服务器就是绑定它的mac地址，并设置好ip、dns、hostname

定义系统

cobbler system add --name=host-188116 --hostname=host-188116 --mac=00:19:B9:E5:34:FE --interface=eth0 --ip-address=172.17.188.116 --subnet=255.255.0.0 --gateway=172.17.188.1 --static=1 --profile=centos5.8-x86_64

查看定义的系统列表

cobbler system list

host-188116

更多参数见cobbler system add --help

四、yum仓库配置管理

4.1 首先导入系统镜像

导入完毕后，进行下面的步骤

4.2 添加镜像

base、updates库使用163的repo源并增加EPEL库

base

cobbler repo add --name=centos5.8-x86_64-Base --mirror=http://mirrors.163.com/centos/5/os/x86_64/

将定义的仓库大写名字Base修改为小写base

cobbler repo edit --name=centos5.8-x86_64-base --mirror=http://mirrors.163.com/centos/5/os/x86_64/ --arch=x86_64 --breed=yum

updates

cobbler repo add --name=centos5.8-x86_64-updates --mirror=http://mirrors.163.com/centos/5/updates/x86_64/ --arch=x86_64 --breed=yum

添加EPEL仓库

cobbler repo add --name=centos5.8-x86_64-epel --mirror=http://mirrors.ustc.edu.cn/epel/5/x86_64/ --arch=x86_64 --breed=yum

4.3 同步yum仓库内容到本地

时间较长，注意磁盘容量是否满足。

cobbler reposync

task started: 2013-03-26_111553_reposync

task started (id=Reposync, time=Tue Mar 26 11:15:53 2013)

………………略…………………………

received on stdout:

received on stderr:

*** TASK COMPLETE ***

4.4 repo添加到profle

安装系统时会自动添加仓库配置

cobbler profile edit --name=centos5.8-x86_64 --repos="centos5.8-x86_64-base centos5.8-x86_64-epel centos5.8-x86_64-updates" --distro=centos5.8-x86_64 --kickstart=/var/lib/cobbler/kickstarts/centos5u8-x64.cfg

删除仓库配置

cobbler repo remove --name=centos5.8-x86_64- updates

4.5 添加更新仓库源计划任务

cobbler reposync --tries=3 --no-fail

加入crontab 每周日更新一次即可

echo "0 2 * * 0 cobbler reposync --tries=3 --no-fail" >> /var/spool/cron/root

注意检查crond是否启动

/etc/init.d/crond status

crond is stopped

/etc/init.d/crond start

chkconfig crond on

4.6 装机自动配置yum

如果想安装系统时自动配置yum，请进行以下配置。

vim /etc/cobbler/settings

yum_post_install_mirror: 1

在装机脚本ks文件加入以下内容

%post

# Start yum configuration

$yum_config_stanza

# End yum configuration

下面的参数PXE安装系统是会引用添加的cobbler repo配置

注意可能将系统、应用部署到较新版本，根据情况而配置

$yum_repo_stanza

这两个参数都来自Kickstart snippets，很值得研究https://github.com/cobbler/cobbler/wiki/Kickstart-snippets

系统安装自动配置的yum

cat /etc/yum.repos.d/cobbler-config.repo

[core-0]

name=core-0

baseurl=http://192.168.5.101/cobbler/ks_mirror/centos5.8-x86_64

gpgcheck=0

五、Cobbler安装操作系统

5.1 安装完系统后默认的密码

这个密码 $default_password_crypted 就是步骤3.6使用openssl passwd -1 生成的密码

grep rootpw /var/lib/cobbler/kickstarts/sample.ks

rootpw --iscrypted $default_password_crypted

5.2 PXE菜单文件

默认菜单文件内容

cat /tftpboot/pxelinux.cfg/default

DEFAULT menu

PROMPT 0

MENU TITLE Centos Automation Install System

5.3 安装系统

将需要安装系统的服务器网卡启用PXE，启动服务器从PXE引导

默认从本地硬盘引导，可以修改，建议还是保持此默认。

选择安装系统centos5.8 即可自动安装系统

Tab键，可以对启动项参数进行编辑

安装源数据说明：

系统centos5.8-x86_64的安装系统数据源，其他系统同理

链接

https://url/cblr/links/centos5.8-x86_64/

/var/www/cobbler/links/centos5.8-x86_64/

是一个链接目录，实际位置如下

ll links/

total 0

lrwxrwxrwx 1 root root 43 Mar 12 13:41 centos5.8-x86_64 -> /var/www/cobbler/ks_mirror/centos5.8-x86_64

5.4 使用Koan重装系统

koan是cobbler的一个辅助工具，koan是kickstart-over-a-network的缩写安装在客户端的使用，koan配合cobbler实现快速重装linux。

koan 在Fedora, Red Hat Enterprise Linux, 和 CentOS工作正常，其他Linux版本应该也不错

koan的相关脚本在此目录内/usr/lib/python2.4/site-packages/koan/

通过EPEL安装的koan版本为koan-2.2.3-2.el5，使用中报错较多，此版本比较稳定koan-1.6.6-1.el5，下载链接ftp://rpmfind.net/linux/epel/5/i386/koan-1.6.6-1.el5.noarch.rpm

关于Koan更多内容见https://github.com/cobbler/cobbler/wiki/Koan

5.4.1 安装koan
