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 | signature | get-loaders | hardlink> [options | -- help]

Distro, profile, and system are three core components of cobbler.

Distro

It is mainly used to define and set the system release version, including the system kernel, boot file, and installation package, which is equivalent to an ISO image of a LINUX system. For example, multiple Release versions have different versions.

Profile

It is mainly used to define the kickstart configuration file, which is customized according to the configuration file during installation.

System

It is mainly used to define kernel parameters, power management, computer names, network interface parameters, and so on (clients), such as configuring IP addresses based on mac addresses, or specifying other network information through the configuration file.

Repo

It is mainly used to configure the yum image source.

1.2 Cobbler distro command

This command is mainly used to add, edit, copy, search, remove, and rename distro.

The format is (take add as an example ):

Cobbler distro add -- name = string -- kernel = path -- initrd = path

[-- Kopts = string] [-- kopts-post = string] [-- ksmeta = string]

[-- Arch = x86 | x86_64 | ia64] [-- breed = redhat | debian | suse]

[-- Template-files = string]

Where:

 

Name	Used to specify the system version. For example, RHEL7
Kernel	Specifies the absolute path of a kernel image file.
Initrd	Specifies the absolute path of a RAM image file.
Kopts	Specifies the kernel command line parameters.
Kopts-post	Same as above
Arch	Used to specify the operating system version platform, such as X86_64
Ksmeta	Is an advanced feature used to replace kickstart Variables
Breed	Used to specify the operating system manufacturers, such as redhat Ubuntu and centos.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Example:

 1 # cobbler distro add --name=Centos6.6-x86_64 --kernel=/mnt/isolinux --initrd=/mnt/isolinux --arch=x86_64 --breed=redhat 2  3 # cobbler distro list 4  5    Centos6.6-x86_64 6  7    Centos7-dvd-x86_64 8  9 # cobbler distro rename –name=Centos6.6-x86_64 –newname=Centos6.9-x86_6410 11 #cobbler distro list12 13    Centos6.9-x86_6414 15    Centos7-dvd-x86_64

1.3 Cobbler profile command

This command is used to add, edit, copy, search, remove, rename a profile.

The format is (take add as an example ):

Cobbler profile add -- name = string -- distro = string [-- kickstart = path]

[-- Kopts = string] [-- ksmeta = string] [-- virt-file-size = gigabytes]

[-- Virt-ram = megabytes] [-- virt-type = string] [-- virt-cpus = integer]

[-- Virt-path = string] [-- virt-bridge = string] [-- server]

[-- Parent = profile]

Name	Specifies the description name of a configuration file.
Distro	Used to associate distro
Kickstart	Used to specify the kickstart file path
Virt -*	Virtualization-related settings
Server	This setting is only available when the client's subnet cannot access the cobbler server.
Parent	This is an advanced feature used to specify the configuration file at the upper level. It can inherit the parameters specified by the parent level.

 

 

 

 

 

 

 

 

 

 

 

 

 

Example:

Static-routers does not need to be concerned, and most machines do not need to set this item

[-- Power-address = string] [-- power-type = string] [-- power-user = string] [-- power-pass = string] [-- power-id = string] these parameters are related to power management.

 

Example:

 1 # cobbler system add --name=Centos6.9-x86_64 --kickstart=/var/lib/cobbler/kickstarts/centos6.9-x86_64.cfg --mac=00:0C:29:41:FC:6C --hostname=backup --profile=Centos6.9-x86_64 --interface ens33 2  3 # cobbler list 4  5 distros: 6  7    Centos6.9-x86_64 8  9    Centos7-dvd-x86_6410 11  12 13 profiles:14 15    Centos6.9-x86_6416 17    Centos7-dvd-x86_6418 19  systems:20 21    Centos6.9-x86_6422 23 repos:24 25 images:26 27 mgmtclasses:28 29 packages:30 31 files:32 33 # cobbler system edit --name=Centos6.9-x86_64 --kickstart=/var/lib/cobbler/kickstarts/centos6.9-x86_64.cfg --mac=00:0C:29:41:FC:6C --hostname=backup --profile=Centos6.9-x86_64 --interface eth0

 

1.5 Cobbler repo command

This command is mainly used to specify a repository source image, not only the source in the installation tree imported using the import method, but also rsync: // URL, SSH local source, http: // URL, FTP: // URL, or local source.

Command Format:

Cobbler repo add -- mirror = url -- name = string [-- rpmlist = list]

[-- Creatrepo-flags = string] [-- keep-updated = Y/N] [-- priority = number]

[-- Arch = string] [-- mirror-locally = Y/N] [-- breed = yum | rsync | rhn]

Mirror	Address of the image repository Source
Name	Definition name
Rpmlist	The following is a list of the names of the software packages separated by spaces, which takes effect only in http: // url, ftp: // url mode. This method can save time, space, and bandwidth. Because the packages in this list will be installed, and none of them will be installed.
Createrepo-flags	When cobbler reposync is running, a special parameter is passed to it. The default value is "-c cache"
Keep-updated	Always repo updates
Priority	Priority. The smaller the number, the higher the priority. The default value is 99. applies to all cobbler image sources.
Arch	Defines the architecture used by the repository. The current system architecture is used by default.
Mirror-locally	Define whether to use local sources or Internet Sources
Breed	Generally, the system knows what we want to do without definition. Of course, you also specify special ones.

Example:

1 # cobbler repo add -- mirror = https://mirrors.aliyun.com/centos/7.3.1611/ OS /x86_64/ -- name = centos7.3-x86_1_3 # cobbler repo list4 5 centos7.3-x86_646 7 # cobbler reposync # synchronize repo, the installation tree of centos7.3.1611 will be downloaded from the Internet to this location. the/var/www/cobbler/repo_1_8 9 command will be introduced here and I think it should be enough. For others, see man cobbler.

1.6 CentOS 6 CD directory Introduction

(1) Packages Directory: contains all binary RPM Packages required for installation.
(2) EFI Directory: A 64-bit EFI-based system boot. The BOOTX64.conf in the BOOT directory is the grub configuration file, which is used to display the BOOT menu.
(3) TRANS. TBL file: record the list of the current directory and regenerate it with the-T parameter of mkisofs, mainly for the long file name.
(4) The discinfo file is the identification information of the installation media .. The treeinfo file records the directory structure of the installer in different installation methods. For example, in PXE mode, kernel = images/pxeboot/vmlinuz and root file system initrd = images/pxeboot/initrd. img.
(5) isolinux Directory: the kernel (vmlinuz) and RAM image (initrd. img) installed on the boot system are loaded into the memory during the boot system, providingLinuxInstall the boot platform. The folder also contains the boot. msg file that displays information in different modes,Splash.jpg is a background image of the boot process in special format (640*480). During InstallationThe boot menu content on the screen is specified in the isolinux/isolinux. cfg file. Press Enter to automatically Enter the graphical interface installation mode. If you press Esc, the "boot:" command prompt will be displayed to Enter the user interaction mode. There will be various operation prompts on the interface. Type "linux text" to enter the text installation mode.
(6) images Directory: contains various boot images. The most important thing is to guide the image file install. img (stage2.img in CentOS 5) to be used for second-stage installation. The anaconda program is in this image file. In addition, boot is used to create a micro boot disc. iso (which has been removed from CentOS 6 and exists in CentOS 5) can be placed in a VFAT partition of USB or other large-capacity bootable media, create a Boot Tool image diskboot. img (in CentOS 5) and pxeboot folders used to create boot media for PXE installation.
