4.8 自定义ks
更改kickstart文件，可为http等，具体cobbler --help查看，这里采用我们自定制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

4.9 配置信息查看

4.10 系统版本列表

cobbler distro list
centos5.8-x86_64
centos5.8-xen-x86_64
centos6.3-x86_64
centos6.4-x86_64

4.11 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

cobbler check
No configuration problems found. All systems go.

cobbler sync
task started: 2013-03-12_171702_sync
task started (id=Sync, time=Tue Mar 12 17:17:02 2013)

*** TASK COMPLETE ***

4.12 创建PXE菜单密码
[align=left]增加装机安全设置菜单密码[/align]
[align=left] [/align]
[align=left]生成hash密码[/align]
[align=left]支持两种不同类型的密码：[/align]

sha1pass mypassword

[align=left]或[/align]

openssl passwd -1 -salt sXiKzkus mypassword

[align=left]我这里选择后者[/align]

# openssl passwd -1 -salt sXiKzkus hexun
$1$sXiKzkus$2DoZ6pfTe8rrc0Si60ecB/

[align=left]编辑配置文件pxedefault，添加如下蓝色部分[/align]

vim /etc/cobbler/pxe/pxedefault.template

DEFAULT menu
PROMPT 0
MENU TITLE Cobbler | http://fedorahosted.org/cobbler MENU MASTER PASSWD $1$sXiKzkus$2DoZ6pfTe8rrc0Si60ecB/
TIMEOUT 200
TOTALTIMEOUT 6000
ONTIMEOUT $pxe_timeout_profile

LABEL local
MENU LABEL (local)
MENU DEFAULT
LOCALBOOT -1

$pxe_menu_items

MENU end

[align=left]配置pxeprofile，增加蓝色部分[/align]

vim /etc/cobbler/pxe/pxeprofile.template
LABEL $profile_name
MENU PASSWD
kernel $kernel_path
$menu_label
$append_line
ipappend 2

[align=left] [/align]
[align=left]修改完毕注意检查、同步配置使其生效[/align]

cobbler check

[align=left] [/align]
[align=left]PXE装机时选择装机系统版本，输入装机密码，效果图[/align]

4.13 定制PXE菜单TITLE

编辑pxedefault文件，

vim /etc/cobbler/pxe/pxedefault.template
MENU TITLE Cobbler | http://fedorahosted.org/cobbler
将原文上面的内容根据自定义进行修改

MENU TITLE Hexun Automation Install System

修改后的文件

DEFAULT menu
PROMPT 0
MENU TITLE Hexun Automation Install System
MENU MASTER PASSWD $1$sXiKzkus$2DoZ6pfTe8rrc0Si60ecB/
TIMEOUT 200
TOTALTIMEOUT 6000
ONTIMEOUT $pxe_timeout_profile

LABEL local
MENU LABEL (local)
MENU DEFAULT
LOCALBOOT -1

$pxe_menu_items

MENU end

修改完毕执行如下两条命令

cobbler check
cobbler sync

4.14 添加指定客户机系统配置到Cobbler

4.14.1 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

4.14.2 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

五、Cobbler Web管理

Cobbler web界面是一个很好的前端，非常容易管理Cobbler
可以添加和删除 system distro profile
可以查看、编辑distros, profiles, subprofiles, systems, repos 、 kickstart文件

5.1 安装cobbler_web

yum -y install cobbler-web

5.2 设置用户名密码

为已存在的用户cobbler重置密码

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

添加新用户

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

5.3 配置cobbler web可以登录

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

5.4 重启Cobbler与http

/etc/init.d/cobblerd restart
/etc/init.d/httpd restart

5.5 访问Cobbler Web页面

浏览器访问登录页面https://172.17.10.14/cobbler_web
输入用户名密码



登录后的页面





web管理相对易于使用管理这里这就不再赘述。
