Automated Installation tool Cobbler Easy installation configuration

The cobbler is installed in the same way as the traditional way, but the relative configuration is simple,

Provides a web interface, but the web is less useful than an OPS engineer.

What I personally prefer is that cobbler can define multiple systems and menus within a set of systems,

It is very practical in large-scale and diverse custom environments.

If you simply install a certain operating system, batch, traditional can be.

The actual production environment does not conflict with DHCP, which is important because DHCP relay is not turned on,

So put it in a new VLAN.

In practice, the server is a static IP, even if the server is restarted and booted from PXE by default from

Local start, so the impact is not big.

server:192.168.1.110

gateway:192.168.1.253
System:centos 6.6 Minimal

Note: I have a problem installing this version on centos6.7, which may be a bug.

To start the installation:
#配置yum源, installation with Epel, basic installation Source No Cobbler
cd/etc/yum.repos.d/
Yum Install-y epel-release
[[email protected] yum.repos.d]# ls
Centos-base.repo Centos-fasttrack.repo Centos-vault.repo Epel-testing.repo
Centos-debuginfo.repo Centos-media.repo Epel.repo

Yum Clean All

Yum install-y Cobbler cobbler-web pykickstart debmirror Cman fence-agents
#pykickstart (check for Kickstart syntax errors)

Service httpd Start
Chkconfig httpd on
Service Cobblerd Start

/etc/init.d/iptables stop
Chkconfig--level iptables off

[Email protected] ~]# Getenforce
Enforcing
Vi/etc/selinux/config
#SELINUX =enforcing
Selinux=disabled

Reboot effective


Cobbler Check #报错, pay attention to check error correction
The following is potential configuration items and that's want to fix:

1:the ' server ' field in/etc/cobbler/settings must is set to something other than localhost, or

Kickstarting features won't work. This should is a resolvable hostname or IP for the boot

Server as reachable by any machines that would use it.
2:for PXE to be functional, the ' next_server ' field in/etc/cobbler/settings must is set to

Something other than 127.0.0.1, and should match the IP of the boot server on the PXE network.
3:change ' disable ' to ' no ' in/etc/xinetd.d/tftp
4:some network boot-loaders is missing from/var/lib/cobbler/loaders, you may run ' cobbler

Get-loaders ' To download them, or, if you are want to handle x86/x86_64 netbooting,

Ensure the installed a *recent* version of the Syslinux package installed and can ignore

This message entirely. Files in the 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 to resolve these requirements.
5:change ' disable ' to ' no ' in/etc/xinetd.d/rsync
6:comment out ' dists ' on/etc/debmirror.conf-proper Debian support
7:comment out ' arches ' on/etc/debmirror.conf-proper Debian support
8:the default password used by the sample templates for newly installed machines

(default_password_crypted in/etc/cobbler/settings) is still set to ' cobbler ' and should be

Changed, try: "OpenSSL passwd-1-salt ' random-phrase-here ' your-password-here '" to generate new

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

At this point, start a virtual machine, put in a network, select PXE boot can load the normal

Log in using the following Web address
Http://192.168.1.110/cobbler_web
Cobbler/cobbler

I use this time in the VirtualBox machine, the choice is bridged, in order to avoid the impact of no line,

Turn off the no-line DHCP feature, and the VirtualBox NIC selects fast III to support PXE boot.
