I. Preface
In the previous blog (), we explained in detail the Cobbler installation and basic configuration. In the final experiment, we have installed Cobbler. In this blog, we will mainly explain how to use the Cobbler command and related configuration directories. Okay. Let's talk about the following nonsense. (Note: The content of this blog is followed by the content of the previous blog. For those who do not know how to install it, refer to the previous blog .)

Ii. Explanation of Cobbler commands
1. Check the Cobbler command.
[Root @ node2 ~] # Cobbler
Usage
=====
Cobbler <distro | profile | system | repo | image | mgmtclass | package | file>...
[Add | edit | copy | getks * | list | remove | rename | report] [options | -- help]
Cobbler <aclsetup | buildiso | import | list | replicate | report | reposync | sync | validateks | version> [options | -- help]
Note: You can see that the cobbler command has many options in the above display. To get help with related options, you only need to add -- help.

2. Explanation of common Cobbler commands
Cobbler check # check cobbler Configuration

Cobbler sync # synchronize configuration to dhcp/pxe and Data Directory

Cobbler list # list all cobbler Elements

Cobbler import # import the installed system image

Cobbler report # list details of each element

Cobbler distro # view imported Release System Information

Cobbler profile # view configuration information

Cobbler system # view the added system information

Cobbler reposync # synchronize the yum repository to a local device

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

Note: It is mainly used to check whether the cobbler configuration is incorrect.
(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 ***

Note: To synchronize the cobbler configuration to the data directory, you must modify some configurations and then synchronize the configurations.
(3). cobbler list
[Root @ node2 ~] # Cobbler list
Distros: # imported release version
Profiles: # installed configuration information
Systems: # added system information
Repos: # yum Repository
Images: # stores all the Kernel and initrd images imported to the release for remote network startup.
Mgmtclasses:
Packages:
Files:

Note: The cobbler list command can be used to list all cobbler elements.
(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, 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

Note: The cobbler import command can import the image file (ISO file) to be installed ).
(5). cobbler report
[Root @ node2 ~] # Cobbler report
Distros:
============
Profiles:
============
Systems:
============
Repos:
============
Images:
============
Mgmtclasses:
============
Packages:
============
Files:
============

Note: As we have not imported any system image files, it is blank. After importing the system image, you can see the detailed information.
(6). cobbler distro
[Root @ node2 ~] # Cobbler distro
Usage
=====
Cobbler distro add
Cobbler distro copy
Cobbler distro edit
Cobbler distro find

Note: The cobbler distro command can not only view the imported release system information, but also add and modify the system information.
(7). cobbler profile
[Root @ node2 ~] # Cobbler profile
Usage
=====
Cobbler profile add
Cobbler profile copy
Cobbler profile dumpvars
Cobbler profile edit
Cobbler profile 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
[Root @ node2 ~] # Cobbler system add -- name = desktop-gnome-1 \
-- Profile = Fedora17-gnome \
-- Mac = 52: 54: 00: 88: f3: 44 \
