Linux 运维自动化之Cobbler的管理与使用详解

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://freeloda.blog.51cto.com/2033581/1320090）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

2.Cobbler 常用命令详解

• cobbler check #检查cobbler配置

• cobbler sync #同步配置到dhcp/pxe和数据目录

• cobbler list #列出所有的cobbler元素

• 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

[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。

(2).cobbler sync

[root@node2 ~]# cobbler sync  
task started: 2013-11-11_133827_sync   
task started (id=Sync, time=Mon Nov 11 13:38:27 2013)

*** TASK COMPLETE ***

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
repos: #yum仓库
p_w_picpaths: #存储所有导入发行版的Kernel和initrd镜像用于远程网络启动
mgmtclasses:
packages:
files:

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   
 --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，cobbler import 命令可以导入我们要安装的镜像文件（ISO文件）。

(5).cobbler report

[root@node2 ~]# cobbler report  
distros:   
==========
profiles:  
==========
systems:  
==========
repos:  
==========
p_w_picpaths:  
==========
mgmtclasses:  
==========
packages:  
==========
files:  
==========

注，由于我们还没有导入任何的系统镜像文件，所以这里显示为空。一会我们导入完系统镜像后，就可以看到详细信息。

(6).cobbler distro

[root@node2 ~]# cobbler distro  
usage   
=====   
cobbler distro add   
cobbler distro copy   
cobbler distro edit   
cobbler distro find   
cobbler distro list   
cobbler distro remove   
cobbler distro rename   
cobbler distro report

注，cobbler distro 命令不但可以查看导入的发行版系统信息还可以增加与修改等。

(7).cobbler profile

[root@node2 ~]# cobbler profile  
usage   
=====   
cobbler profile add   
cobbler profile copy   
cobbler profile dumpvars   
cobbler profile edit   
cobbler profile find   
cobbler profile getks   
cobbler profile list   
cobbler profile remove   
cobbler profile rename   
cobbler profile report

注，cobbler profile命令不但可以查看Kickstart文件而且还可以编辑与删除此文件。

(8).cobbler system

[root@node2 ~]# cobbler system  
usage   
=====   
cobbler system add   
cobbler system copy   
cobbler system dumpvars   
cobbler system edit   
cobbler system find   
cobbler system getks   
cobbler system list   
cobbler system poweroff   
cobbler system poweron   
cobbler system powerstatus   
cobbler system reboot   
cobbler system remove   
cobbler system rename   
cobbler system report

注，cobbler system 命令可以将cobbler的配置安装文件与客户端相关联。下面是具体的案例，

[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
[root@node2 ~]# cobbler system add --name=desktop-gnome-1 \
                   --profile=Fedora17-gnome \
                   --mac=52:54:00:88:f3:44 \
                   --ip-address=192.168.122.11
[root@node2 ~]# cobbler system report

(9).cobbler reposync

[root@node2 ~]# cobbler reposync
task started: 2013-11-11_144127_reposync
task started (id=Reposync, time=Mon Nov 11 14:41:27 2013)
hello, reposync
run, reposync, run!
*** TASK COMPLETE ***

注，cobbler reposync命令可以同步远程的yum源到本地。

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://freeloda.blog.51cto.com/2033581/1320090。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
p_w_picpaths  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

(6).cobbler report 查看一下详细信息

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

(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
