The specific steps to install Cobbler under Linux

Using cobbler under Linux can quickly establish a Linux network installation environment, which greatly reduces the technical threshold for Linux network installation. How to install Cobbler on Linux system? Let's learn together.

Introduction to cobbler

cobbler is an open source project supported by Redhat for deploying and installing systems. So support for the Redhat series os is better. However, support for ubuntu is very poor. There are quite a few settings in cobbler that are only valid for redhat, and also because of the differences in the installation of different distributions. Cobbler feels as nervous as Ubuntu.

Cobbler is more than just a pxe server. He can also manage dns(bind), dhcp. In general data center or production environment, dhcp is not allowed, but pxe must be dhcp, so we need to allocate IP according to mac address, so dhcp will not affect the network.

1. Install cobbler

Configure epel source in advance http://mirrors.ustc.edu.cn/fedora/epel/6/i386/

[root@ 60sec /]# yum -y install cobbler

[root@60sec /]# service httpd start

Starting httpd: [ OK ]

[root@60sec /]# service cobblerd start

Starting cobbler daemon: [OK]

2, cobbler check command execution problem to check stored, one by one and then follow the prompts solution

[root @60sec /]# vim /etc/cobbler/settings

next_server: 192.168.83.137

server: 192.168.83.137

manage_tftpd: 0

[ Root@60sec /]# yum -y install syslinux

[root@60sec /]# chkconfig rsync on

[root@60sec /]# yum -y install pykickstart

[root@60sec /]# openssl passwd -1 -salt ‘openssl rand -hex 4’

Password:

$1$openssl $.oduSwbhLj6jqAwVsLo/H1

[roo t@60sec /]# vim /etc/cobbler/settings

default_password_crypted: “penssl $.oduSwbhLj6jqAwVsLo/H1”

[root@60sec /]# cd /usr/share/syslinux /

[root@60sec syslinux]# cp -r . /* /var/lib/cobbler/loaders/

3, install dhcp service

[root@60sec /]# yum -y install dhcp

[root@60sec /]# cp /usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample /etc/dhcp/dhcpd.conf

[root@60sec /]# vim /etc/dhcp/dhcpd .conf

option domain-name <;60sec.com”;

option domain-name-servers 192.168.83.137;

default-lease-time 43300;

max-lease-time 86500;

subnet 192.168.83.0 netmask 255.255.255.0 {

range 192.168.83.50 192.168.83.100;

option routers 192.168. 83.137;

}

next-server 192.168.83.137;

filename=“pxelinux.0”;

[root@60sec /]# Service dhcpd start

Starting dhcpd: [ OK ]

4, turn on tftp service

[root@60sec /]# chkconfig tftp on

[root @60sec /]# service xinetd start

Starting xinetd: [ OK ]

5, define distro, mount the CD and import

[root@60sec /]# mount -r /dev/cdrom /media/

[root@60sec /]# cobbler import -- Name=centos-6.5-x86_64 --path=/media

6. If there is a kickstart file, use “--kickstart=/path/to/kickstart_file” to import, you can also use the following command to detect,

You can use system-config-kickstart to make a kickstart file. The cobbler ks file is placed under /var/lib/cobbler/kickstarts/by default. The ks file can be customized according to different needs.

[root@60sec mnt]# ksvalidator centos6.x86_64.cfg

7. Set profile, profile can be understood as classification according to installation requirements.

[root@60sec mnt]# cobbler profile add --name=CenTos-6.5-x86_64-basic --distro=centos-6.5-x86_64 --kickstart=/mnt/centos6.x86_64.cfg

[root@60sec mnt]# cobbler profile list

CenTos-6.5-x86_64-basic

Centos-6.5-x86_64

[root@60sec mnt] # cobbler sync

[root@60sec mnt]# service cobblerd restart

Modifyable information

[root@60sec mnt]# vim /var/lib/tftpboot/pxelinux.cfg /default

8, re-create the virtual machine test

the above is a concrete step to install cobbler under Linux, and follow the steps described above can be easily installed cobbler, Is it easy? Give it a try.
