一、前言
在上一篇部落格中（  ）我們詳細的講解了Cobbler安裝與基本配置，在最後的實驗中我們已經安裝好了Cobbler。在這一篇部落格中我們來主要講解一下Cobbler命令的使用與相關配置目錄的說明。好了，下面廢話不多說直接上乾貨。（注，這一篇部落格的內容是跟著上一篇部落格的內容寫的，對安裝不瞭解的博友可以先參考上一篇部落格。）

二、Cobbler 命令詳解

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

注，主要用於檢查cobbler配置是否有錯。
(2).cobbler sync

*** TASK COMPLETE ***

注，同步cobbler配置到資料目錄中，更改某些配置後得執行一下，同步一下配置。
(3).cobbler list
[root@node2 ~]# cobbler list 
distros: #匯入的發行版本
profiles: #安裝的配置資訊
systems: #增加的系統資訊
repos: #yum倉庫
images: #儲存所有匯入發行版的Kernel和initrd鏡像用於遠程網路啟動
mgmtclasses:
packages:
files:

注，用cobbler list 命令可以列出cobbler所有元素。
(4).cobbler import

Usage: cobbler [options]
Options: 
 -h, --help      show this help message and exit 
 --arch=ARCH      OS architecture being imported

==========
profiles: 
==========
systems: 
==========
repos: 
==========
images: 
==========
mgmtclasses: 
==========
packages: 
==========
files: 
==========

注，由於我們還沒有匯入任何的系統鏡像檔案，所以這裡顯示為空白。一會我們匯入完系統鏡像後，就可以看到詳細資料。

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 \
