In the production environment will inevitably encounter, some servers need to install CentOS, some servers need to install Ubuntu, or some systems need to install centos6.4 some systems need to install centos6.5, then PXE can not meet our requirements. This article describes cobbler to implement this functionality.

Cobbler Required Services:


u Rsync


u DNS(On demand)

Cobbler Command:

u Import

u Sync

u Reposync

u Build ISO

Core concept:

Distros: Define boot kernel,initrd file, etc.

Profiles: Specify Kickstart to specify level


First,Installing Cobbler

Prerequisite:Cobbler is provided by the Epel Source, so it is necessary to configure the Yum that points to Epel beforehand The source can perform the installation process similar to the following.

Note Turn off selinux


RPM-IVH epel-release-6-8.noarch.rpm

Yum Clean All

# yum Install cobbler Cobbler-web pykickstart debmirror-y

# service Htt PD Start

# service Cobblerd Start

# Cobbler Check

Perform thecobbler Check command to examine the problems that are stored, and then follow the prompts to resolve them individually. The common problems are as follows:

1:the ' server ' field in/etc/cobbler/settings must is set to something other than localhost, or kickstarting features WI  ll not work. This should is a resolvable hostname or IP for the boot server as reachable by all machines that would use it.

2 : for pxe to be functional,  the  ' Next_server '  field in /etc/cobbler/settings must be set to  something other than, and should match the ip of  the boot server on the pxe network.

3 : some network boot-loaders are  missing from /var/lib/cobbler/loaders, you may run  ' cobbler  Get-loaders '  to download them, or, if you only want to  handle x86/x86_64 netbooting, you may ensure that you have  installed a *recent* version of the syslinux package installed  and can ignore this message entirely.  files in this  directory, should you want to support all architectures, should  include pxelinux.0, menu.c32, elilo.efi, and yaboot. the  ' cobbler  Get-loaders '  command is the easiest way to resolve these  Requirements.

4:change ' disable ' to ' no ' in/etc/xinetd.d/rsync

5:comment ' dists ' on/etc/debmirror.conf for proper Debian support

6:comment ' arches ' on/etc/debmirror.conf for proper Debian support

7:the default password used by the sample templates for newly installed machines (default_password_crypted IN/ETC/COBBL Er/settings) is still set to ' cobbler ' and should be changed, try: "OpenSSL passwd-1-salt ' Random-phrase-here ' Your-pas Sword-here ' "To generate new one

8:fencing tools were not found, and is required to use the (optional) power management features. Install Cman or fence-agents to use them

Restart Cobblerd and then run ' Cobbler Sync ' to apply changes.

The workarounds for the above problems are as follows:

1. Modify The value of the server parameter in the /etc/cobbler/settings file to provide cobbler The corresponding IP address or hostname of the service host, such as;

2 next_server pxe The host of the service corresponding ip address, such as

3, if the current node can access the Internet, execute "cobbler get-loaders" command, otherwise, you need to install the syslinux Package, and then copy /usr/share/syslinux/{pxelinux.0,memu.c32} and other files to the /var/lib/cobbler/loaders/ directory;

4, the implementation of "chkconfig rsyncon" command can be;

5.Note "@dists =" Sid " in the /etc/debmirror.conf file; "one line;

6.Note "@arches =" i386 " in the /etc/debmirror.conf file; "one line;

7.Execute "OpenSSL passwd-1-salt $ (OpenSSL rand-hex 4)" to generate the password and replace it with /etc/cobbler/settings The value of the default_password_crypted parameter in the file ;

8, the implementation of "yum install cman fence-agents" command to install the corresponding package can be;

Then restart cobblerd, then perform "cobbler sync" To synchronize the new configuration to cobbler.

Second, Install DHCP

Yum Install Dhcp-y


Option Domain-name "";

Option Domain-name-servers,;

Default-lease-time 43200;

Max-lease-time 86400;

Log-facility Local7;

Subnet netmask {


Option routers;



Filename= "pxelinux.0";

Service DHCPD Start

Service xinetd Restart

Cobbler Sync
