环境：    
OEL6.3 x64 (CentOS6.3 x64)     
网络环境中无其它DHCP服务器 

本文出自：http://koumm.blog.51cto.com

一、 cobbler安装准备 

1. 关闭iptables与selinux 

1 2 3

# chkconfig iptables off # vi /etc/selinux/config SELINUX=disabled

1	# sestatus  重启后查看

2. 安装源准备并安装cobbler软件 

说明：基础源与epel源。 

1 2	rpm -ivh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm yum -y install cobbler cobbler-web httpd rsync tftp-server xinetd dhcp python-ctypes debmirror pykickstart fence-agents

二、 配置tftp-server与rsync 

开启tftp与rsync服务 

1 2	sed -i '/disable/c disable = no' /etc/xinetd.d/tftp sed -i -e 's/= yes/= no/g' /etc/xinetd.d/rsync

三、配置cobbler 

1. 配置httpd配置文件 

1 2	# vi /etc/httpd/conf/httpd.conf ServerName 127.0.0.1:80

2. 配置cobbler主配置文件 

1 2 3 4

sed -i 's/next_server: 127.0.0.1/next_server: 192.168.1.10/g' /etc/cobbler/settings sed -i 's/server: 127.0.0.1/server: 192.168.1.10/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

 

3. 配置cobbler web登录认证配置文件 

(1) 修改认证文件

1	sed -i 's/module = authn_denyall/module = authn_configfile/g' /etc/cobbler/modules.conf

(2) 设置用户名密码：

 

1	htdigest /etc/cobbler/users.digest "Cobbler" cobbler

4. 生成Cobbler安装系统root初始密码 

(1)这里生成密钥和配置默认密钥，ks文件引用 

1 2	# openssl passwd -1 -salt 'random-phrase-here' '111111' $1$random-p$WbZ3JxhRzCS/1Ne4S9g4Z.

(2) 将上面的加密串加入cobbler配置文件中。 

1 2 3

# vi /etc/cobbler/settings # 修改为如下配置 default_password_crypted: "$1$random-p$WbZ3JxhRzCS/1Ne4S9g4Z."

四、配置DHCP与启动cobbler相关服务 

1. 配置dhcp配置文件 

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

# mv /etc/cobbler/dhcp.template /etc/cobbler/dhcp.template.bak # vi /etc/cobbler/dhcp.template ddns-update-style interim; allow booting; allow bootp; ignore client-updates; set vendorclass = option vendor-class-identifier; subnet 192.168.1.0 netmask 255.255.255.0 { option routers 192.168.1.1; option domain-name-servers 202.100.192.68; option subnet-mask 255.255.255.0; range dynamic-bootp 192.168.1.120 192.168.1.254; filename "/pxelinux.0"; default-lease-time 21600; max-lease-time 43200; next-server $next_server; }

2. 需要启动的服务 

1 2 3 4 5 6 7 8

chkconfig httpd on chkconfig xinetd on chkconfig dhcpd on chkconfig cobblerd on service httpd start service xinetd start service dhcpd start service cobblerd start

五、效验cobbler安装条件 

1. 修复cobbler check时出现的第一条错误信息 

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

[root@pxe ~]# cobbler get-loaders task started: 2013-12-15_191305_get_loaders task started (id=Download Bootloader Content, time=Sun Dec 15 19:13:05 2013) downloading http://www.cobblerd.org/loaders/README to /var/lib/cobbler/loaders/README downloading http://www.cobblerd.org/loaders/COPYING.elilo to /var/lib/cobbler/loaders/COPYING.elilo downloading http://www.cobblerd.org/loaders/COPYING.yaboot to /var/lib/cobbler/loaders/COPYING.yaboot downloading http://www.cobblerd.org/loaders/COPYING.syslinux to /var/lib/cobbler/loaders/COPYING.syslinux downloading http://www.cobblerd.org/loaders/elilo-3.8-ia64.efi to /var/lib/cobbler/loaders/elilo-ia64.efi downloading http://www.cobblerd.org/loaders/yaboot-1.3.14-12 to /var/lib/cobbler/loaders/yaboot downloading http://www.cobblerd.org/loaders/pxelinux.0-3.61 to /var/lib/cobbler/loaders/pxelinux.0 downloading http://www.cobblerd.org/loaders/menu.c32-3.61 to /var/lib/cobbler/loaders/menu.c32 downloading http://www.cobblerd.org/loaders/grub-0.97-x86.efi to /var/lib/cobbler/loaders/grub-x86.efi downloading http://www.cobblerd.org/loaders/grub-0.97-x86_64.efi to /var/lib/cobbler/loaders/grub-x86_64.efi *** TASK COMPLETE *** [root@pxe ~]#

2. 修复debian/ubuntu系统安装选项支持包 

1 2 3 4

# vi /etc/debmirror.conf 说明：前提是安装debmirror pykickstart这两个包，注释掉如下两行。 #@dists="sid"; #@arches="i386";

3. cobbler check效验环境 

1 2 3 4

[root@pxe ~]# cobbler check The following are potential configuration items that you may want to fix: 1 : service dhcpd is not running Restart cobblerd and then run 'cobbler sync' to apply changes.

4. 按上文校验提示操作修复 

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43

说明：本节在前面已经考虑过cobbler check的错误提示了，大部分处理了。 

5. 重启cobblerd 与xinetd服务 

1 2 3 4 5 6

[root@pxe ~]# service cobblerd restart Stopping cobbler daemon:                                   [确定] Starting cobbler daemon:                                   [确定] [root@pxe ~]# service xinetd restart 停止 xinetd：                                              [确定] 正在启动 xinetd：                                          [确定]

六、导入linux ISO安装镜像 

1. 挂载ISO光盘镜像 

1	# mount /dev/cdrom /mnt

2. 开始导入光盘镜像 

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41

说明: cobbler将镜像拷贝一份放在/var/www/cobbler/ks_mirrors/CentOS-5.9-x86_64目录下。   
同时会创建一个名字为CentOS-5.9-x86_64的一个发布版本，以及一个名字为CentOS-5.9-x86_64的profile文件。 

1 2 3 4 5 6 7 8 9 10 11 12 13

[root@pxe kickstarts]# cobbler list distros: Centos-5.9-x86_64 Centos-5.9-xen-x86_64 profiles: Centos-5.9-x86_64 Centos-5.9-xen-x86_64 systems: repos: images: mgmtclasses: packages: files:

七、修改安装更改kickstart文件 

1. 相关知识内容 

说明：   
默认kickstart文件是/var/lib/cobbler/kickstarts/sample.ks，需要手动为每个发行版单独指定, 或单独修改。 

1 2 3 4

# cobbler distro list Centos-5.9-x86_64 Centos-5.9-xen-x86_64 #

2. 手动创建自定义新的kickstart文件 

1	vi /var/lib/cobbler/kickstarts/centos-5.9.ks

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58

install text cdrom lang zh_CN.UTF-8 keyboard us reboot url --url=http://192.168.1.10/cobbler/ks_mirror/Centos-5.9-x86_64 network --device eth0 --bootproto dhcp --noipv6 --hostname oa rootpw --iscrypted $1$H0bnNoWM$HE1R/mWv6LqbhUGI8Xw/t. firewall --disabled authconfig --enableshadow --enablemd5 selinux --disabled timezone Asia/Shanghai bootloader --location=mbr --driveorder=sda --append="rhgb quiet" # The following is the partition information you requested # Note that any partitions you deleted are not expressed # here so unless you clear all partitions first, this is # not guaranteed to work clearpart --all --initlabel part /boot --fstype ext3 --size=200 --asprimary part swap --size=2048 part / --fstype ext3 --size=200 --grow %packages @admin-tools @base @chinese-support @core @development-libs @development-tools @dialup @editors @gnome-desktop @games @graphical-internet @graphics @java @legacy-software-development @legacy-software-support @office @printing @sound-and-video @text-internet @base-x system-config-kickstart kexec-tools iscsi-initiator-utils fipscheck squashfs-tools device-mapper-multipath sgpio imake emacs libsane-hpaio xorg-x11-utils xorg-x11-server-Xnest xorg-x11-server-Xvfb %post service sendmail stop

 

3. 修改profile指定新的KS启动文件，按角色进行分类 

说明   
1. 选择Centos-5.9-x86_64，将采用Centos-5.9-x86_64安装源，并通过/var/lib/cobbler/kickstarts/centos-5.9.ks文件进行全自动安装。    
2. 如有其它发行版，导入完镜像后，可以通过以下方式进行修改，否则将采用默认KS进行安装系统。    
3. 也可以采用不同的ks文件来实现个性能自动安装，如下面第三条add命令，添加一个半自动的ks文件。    
4. 如果没有按下面内容修改指定ks文件的话，引导菜单只显示Centos-5.9-x86_64默认一项。指定ks文件后，会在启动菜单中显示。 

1	# cobbler profile edit --name=Centos-5.9-x86_64 --distro=Centos-5.9-x86_64 --kickstart=/var/lib/cobbler/kickstarts/centos-5.9.ks

示例：   

1 2	# cobbler profile edit --name=Centos-5.9-xen-x86_64 --distro=Centos-5.9-x86_64 --kickstart=/var/lib/cobbler/kickstarts/centos-5.9-xen.ks # cobbler profile add --name=Centos-5.9-half-auto --distro=Centos-5.9-x86_64 --kickstart=/var/lib/cobbler/kickstarts/centos-5.9-halfauto.ks

如图所示： 

4. 更改profile名称

1	# cobbler profile rename --name=Centos-5.9-x86_64 --newname=CentOS-5U9-x64

5. 删除profile配置，需要删除的profile名称为Centos-5.9-x86_64，删除后，安装启动菜单相关项消失。

1	# cobbler profile remove --name=Centos-5.9-x86_64

 

八、添加指定客户机系统配置到Cobbler

1. 指定一个网段使用特定的装机配置

1	cobbler system add --name=test_000 --ip=192.168.1.0/24 --profile=Centos-5.9-x86_64

 

2. 添加一个指定服务器的装机配置

指定服务器的mac地址，并设置好主机名、IP地址等信息，需要提示知道服务器MAC地址，根据MAC应用到具体机器上。    

1 2	还可以指定ks参数。--kickstart=/var/lib/cobbler/kickstarts/webserver.ks cobbler system add --name=test_001 --hostname=test_001 --mac=00:0C:29:E3:81:32 --interface=eth0 --ip-address=192.168.1.123 --subnet=255.255.255.0 --gateway=192.168.1.1 --static=1 --profile=Centos-5.9-x86_64

3. 修改system配置 

机器IP地址变更为192.168.10.110    

1	cobbler system add --name=test_001 --ip=192.168.1.110

变更system配置名称   

1	cobbler system rename --name=test001 --newname=abc

4. 删除system配置 

需要删除的profile名称为test_001   

1	cobbler system remove --name=test_001

5. 查看定义的系统列表

 

1 2	cobbler system list test_001

九、安装客户端操作系统 

(1) 通过网卡pxe启动

(2) 自动完成安装 

 

十、重装客户端操作系统 

1 2	wget ftp://rpmfind.net/linux/epel/5/i386/koan-1.6.6-1.el5.noarch.rpm rpm -ivh koan-1.6.6-1.el5.noarch.rpm

查看cobbler server上的配置文件，对于centos5.x 的系统koan不能采用yum安装，否则会因python版本过低而报错。

1	# koan --server=192.168.1.10 --list=profiles

1 2 3 4 5 6 7 8 9 10 11

# reboot

reboot重启服务器后，客户端服务器会自动重新安装操作系统
