Linux 运维自动化之Cobbler的管理与使用详解-服务器评测

大纲
一、前言
二、Cobbler 命令详解
三、导入要安装的镜像文件
四、客户端安装操作系统
注，操作系统 CentOS 6.4 x86_64，软件版本 Cobbler-2.4.0-1。（目前最新版）

一、前言
在上一篇博客中（ http://www.linuxidc.com/Linux/2013-11/92319.htm ）我们详细的讲解了Cobbler安装与基本配置，在最后的实验中我们已经安装好了Cobbler。在这一篇博客中我们来主要讲解一下Cobbler命令的使用与相关配置目录的说明。好了，下面废话不多说直接上干货。（注，这一篇博客的内容是跟着上一篇博客的内容写的，对安装不了解的博友可以先参考上一篇博客。）

二、Cobbler 命令详解

cobbler import #导入安装的系统镜像

cobbler report #列出各元素的详细信息

cobbler distro #查看导入的发行版系统信息

cobbler profile #查看配置信息

cobbler system #查看添加的系统信息

cobbler reposync #同步yum仓库到本地

(1).cobbler check
12 [root@node2 ~]# cobbler check
No configuration problems found. All systems go.

注，主要用于检查cobbler配置是否有错。

注，同步cobbler配置到数据目录中，更改某些配置后得执行一下，同步一下配置。
(3).cobbler list
[root@node2 ~]# cobbler list
distros: #导入的发行版本
profiles: #安装的配置信息
systems: #增加的系统信息

注，用cobbler list 命令可以列出cobbler所有元素。
(4).cobbler import
[root@node2 ~]# cobbler import –help
Usage: cobbler [options]
Options:
-h, –help show this help message and exit

usage
=====
cobbler distro add
cobbler distro copy
cobbler distro edit
cobbler distro find

[root@node2 ~]# cobbler system add –name=desktop-xfce-1 \
–profile=Fedora17-xfce \
–mac=52:54:00:b8:5e:8f \
–ip-address=192.168.122.10

三、导入要安装的镜像文件
1.镜像文件
CentOS-5.5-x86_64-bin-DVD-1of2.iso

CentOS-6.4-x86_64-bin-DVD1.iso

注，这里我们主要演示两个系统。一个是CentOS 5.5，另一个是CentOS6.4。这两个系统是现在比较常用的两个，重点给大家演示一下怎么导入系统。(在上篇博客中我们已经安装好Cobbler，并修改好相关配置，但是没有导入任何系统，不清楚的博友可以先参考一下上一篇博客： http://www.linuxidc.com/Linux/2013-11/92319p2.htm 。下面我们就来具体演示一下！)

2.导入CentOS 5.5镜像
(1).选择CentOS 5.5镜像

(2).选择 “使用ISO映像文件”

(3).选择 “CentOS-5.5-x86_64-bin-DVD-1of2.iso”，并确定。

(4).挂载镜像
[root@node2 ~]# mount /dev/cdrom /mnt
mount: block device /dev/sr0 is write-protected, mounting read-only
[root@node2 ~]# cd /mnt/
[root@node2 mnt]# ls
CentOS RELEASE-NOTES-cs RELEASE-NOTES-en_US RELEASE-NOTES-ja RELEASE-NOTES-ro
EULA RELEASE-NOTES-cs.html RELEASE-NOTES-en_US.html RELEASE-NOTES-ja.html RELEASE-NOTES-ro.html
GPL RELEASE-NOTES-de RELEASE-NOTES-es RELEASE-NOTES-nl repodata
images RELEASE-NOTES-de.html RELEASE-NOTES-es.html RELEASE-NOTES-nl.html RPM-GPG-KEY-beta
isolinux RELEASE-NOTES-en RELEASE-NOTES-fr RELEASE-NOTES-pt_BR RPM-GPG-KEY-CentOS-5
NOTES RELEASE-NOTES-en.html RELEASE-NOTES-fr.html RELEASE-NOTES-pt_BR.html TRANS.TBL
(5).使用cobbler import命令导入镜像
[root@node2 mnt]# cobbler import –help
Usage: cobbler [options]
Options:
-h, –help show this help message and exit
–arch=ARCH OS architecture being imported
–breed=BREED the breed being imported
–os-version=OS_VERSION
the version being imported
–path=PATH local path or rsync location
–name=NAME name, ex ‘RHEL-5’
–available-as=AVAILABLE_AS
tree is here, don’t mirror
–kickstart=KICKSTART_FILE
assign this kickstart file
–rsync-flags=RSYNC_FLAGS
pass additional flags to rsync

注，主要有以下几个参数–path 指定导入镜像的路径，–name 指定导入镜像的名称，–arch 指定导入镜像的架构(32位还是64位)。还有需要说明的是这里导入的时间相对较长大概在5-10分钟左右，请大家耐心等待。下面是具体的导入过程，
[root@node2 ~]# cobbler import –path=/mnt/ –name=CentOS-5.5 –arch=x86_64
task started: 2013-11-11_154941_import
task started (id=Media import, time=Mon Nov 11 15:49:41 2013)

*** TASK COMPLETE ***

注，从上面显示信息所知，cobbler会将镜像中的拷贝到本地一份，放在/var/www/cobbler/ks_mirrors下的CentOS-5.5-x86_64目录下。同时会创建一个名字为CentOS-5.5-x86_64的一个发布版本，以及一个名字为CentOS-5.5-x86_64的profile文件。下面我们来具体查看一下，
[root@node2 cobbler]# cobbler list
distros:
CentOS-5.5-x86_64
CentOS-5.5-xen-x86_64
profiles:
CentOS-5.5-x86_64
CentOS-5.5-xen-x86_64

好了，到这里我们的CentOS5.5的镜像文件就导入完成了，同样的CentOS 6.4导入方法与CentOS5.5是一样的，在下面我们会为大家具体演示。下面我们为大家演示一下，用客户端安装操作系统！

四、客户端安装操作系统

1.实验拓扑

2.在VMWare中新建客户端

(1).新建虚拟机

Linux 运维自动化之Cobbler的管理与使用详解

(2).这里我们选择自定义

(3). 这里默认就好，选择“下一步”。

(4).这里选择“以后安装操作系统”

(5).这里我们选择“CentOS 64-bit”

(6).这里我们设置虚拟机名称与存放位置

(7).这里我们设置CPU个数

(8).这里我们设置虚拟机的内存

(9).这里我们设置一下网络连接，这里我们设置的“桥接”

(10).这里我们选择一下I/O设备的控制器

(11).创建一个磁盘

(12).选择磁盘类型

(13).选择磁盘存放的位置

(14).到这里我们虚拟机就新建完成

(15).结果如下

3.具体的安装过程
(1).安装前检查
