cobbler批量安装linux(centos6.5)

浏览数：50 / 时间：2015年06月20日

1.安装 cobbler

(1).安装第三方软件库所需要的包

#cd /tmp

#wget http://mirrors.ustc.edu.cn/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm

#rpm -ivh epel-release-6-8.noarch.rpm

(2).安装 dhcp

#yum -y install dhcp

(3). 安装其他的相关软件

#yum -y install tftp rsync xinetd httpd

(4). 安装 cobbler

#yum -y install cobbler

2.关闭 selinux 和防火墙

#setenforce 0

#service iptables stop

3.启动 cobbler及相关服务

#service httpd start

#chkconfig httpd on

#service cobblerd start

#chkconfig cobblerd on

4.设置 cobbler

(1).cobbler check

执行完后会出现以下信息

The following are potential configuration items that you may want to fix:

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

2 : For PXE to be functional, the ‘next_server‘ field in /etc/cobbler/settings must be set to something other than 127.0.0.1, and should match the IP of the boot server on the PXE network.

3 : SELinux is enabled. Please review the following wiki page for details on ensuring cobbler works correctly in your SELinux environment:

https://github.com/cobbler/cobbler/wiki/Selinux

4 : 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.

5 : change ‘disable‘ to ‘no‘ in /etc/xinetd.d/rsync

6 : debmirror package is not installed, it will be required to manage debian deployments and repositories

7 : ksvalidator was not found, install pykickstart

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

9 : fencing tools were not found, and are 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.

(2).根据要求修改

说明下1怎么做

修改这个/etc/cobbler/settings配置文件中的server参数为本服务器的ip

说明下2怎么做

修改这个/etc/cobbler/settings配置文件中的next_server参数为本服务器的ip

说明下3怎么做

如果你开启了selinux这个安全东西，需要关闭它

#setenforce 0

或者修改配置文件/etc/selinux/config中的SELINUX=disabled，这一步需要重启操作系统

说明下4怎么做

#cobbler get-loaders

说明下5怎么做

修改配置文件/etc/xinetd.d/rsync中的disable = no

说明下6怎么做(其实6可以不做)

#yum -y install ed patch perl perl-Digest-SHA1 perl-libwww-perl perl-Compress-Zlib perl-LockFile-Simple

#rpm -ivh debmirror-20090807-1.el5.noarch.rpm

#vim /etc/debmirror.conf

注释以下两行

#@dists="sid";

#@arches="i386";

说明下7怎么做

#yum -y install pykickstart

说明下8怎么做

修改cobbler用户的默认密码,可以用如下命令生成密码,并使用生成后的密码替换/etc/cobbler/settings中的密码,找到这一行default_password_crypted

以下是生成密码的命令

#openssl passwd -1 -salt ‘daoke‘ ‘mirrtalk‘

会产生如下密码

$1$daoke$p2T8SDDadwH.qOeQIUeUR/

替换即可

修改过程中，多次使用cobbler check查看，知道所有的问题解决

(3)重启cobbler并应用应用所有的设置

#service cobblerd restart

#cobbler sync

5.修改DHCP模板，确保DHCP分配的地址和cobbler在同一个网段，记得修改/etc/cobbler/settings的参数manage_dhcp 设为 1，以便管理 DHCP

vim /etc/cobbler/dhcp.template

# ******************************************************************

# Cobbler managed dhcpd.conf file

# generated from cobbler dhcp.conf template ($date)

# Do NOT make changes to /etc/dhcpd.conf. Instead, make your changes

# in /etc/cobbler/dhcp.template, as /etc/dhcpd.conf will be

# overwritten.

# ******************************************************************

ddns-update-style interim;

allow booting;

allow bootp;

ignore client-updates;

set vendorclass = option vendor-class-identifier;

option pxe-system-type code 93 = unsigned integer 16;

subnet 192.168.5.0 netmask 255.255.255.0 {

option domain-name-servers 192.168.5.2;

option subnet-mask 255.255.255.0;

range dynamic-bootp 192.168.5.110 192.168.5.220;

default-lease-time 21600;

max-lease-time 43200;

next-server $next_server;

class "pxeclients" {

match if substring (option vendor-class-identifier, 0, 9) = "PXEClient";

if option pxe-system-type = 00:02 {

filename "ia64/elilo.efi";

} else if option pxe-system-type = 00:06 {

filename "grub/grub-x86.efi";

} else if option pxe-system-type = 00:07 {

filename "grub/grub-x86_64.efi";

} else {

filename "pxelinux.0";

}

#for dhcp_tag in $dhcp_tags.keys():

## group could be subnet if your dhcp tags line up with your subnets

## or really any valid dhcpd.conf construct ... if you only use the

## default dhcp tag in cobbler, the group block can be deleted for a

## flat configuration

# group for Cobbler DHCP tag: $dhcp_tag

group {

#for mac in $dhcp_tags[$dhcp_tag].keys():

#set iface = $dhcp_tags[$dhcp_tag][$mac]

host $iface.name {

hardware ethernet $mac;

#if $iface.ip_address:

fixed-address $iface.ip_address;

#end if

#if $iface.hostname:

option host-name "$iface.hostname";

#end if

#if $iface.netmask:

option subnet-mask $iface.netmask;

#end if

#if $iface.gateway:

option routers $iface.gateway;

#end if

#if $iface.enable_gpxe:

if exists user-class and option user-class = "gPXE" {

filename "http://$cobbler_server/cblr/svc/op/gpxe/system/$iface.owner";

} else if exists user-class and option user-class = "iPXE" {

filename "http://$cobbler_server/cblr/svc/op/gpxe/system/$iface.owner";

} else {

filename "undionly.kpxe";

}

#else

filename "$iface.filename";

#end if

## Cobbler defaults to $next_server, but some users

## may like to use $iface.system.server for proxied setups

next-server $next_server;

## next-server $iface.next_server;

}

#end for

}

#end for

注意！！！！

vim /etc/dhcp/dhcpd.conf

ddns-update-style interim;

allow booting;

allow bootp;

} else {

filename "pxelinux.0";

}

group {

}

启动dhcp及开机自动启动

#service dhcpd start

#chkconfig dhcpd on

6.挂在centos6.5安装盘，生成安装镜像

#mkdir /mnt/mirrtalk65miso/

#mount -o loop /data/mirrtalk-6.5-x86_64-minimal.iso /mnt/mirrtalk65miso/

#cobbler import --path=/mnt/mirrtalk65miso/ --name=mirrtalk-6.5-x86_64 --arch=x86_64

查看已导入的

#cobbler distro list

#cobbler list

#cobbler report

7.修改mirrtalk65miso.ks

#vim /var/lib/cobbler/kickstarts/mirrtalk65miso.ks

auth --useshadow --enablemd5

bootloader --location=mbr

clearpart --all --initlabel

text

firewall --disabled

firstboot --disabled

keyboard us

lang en_US.UTF-8

network --onboot yes --bootproto dhcp --noipv6

url --url=$tree

$yum_repo_stanza

reboot

rootpw mirrtalk

selinux --disabled

skipx

timezone --utc Asia/Shanghai

install

zerombr yes

part /boot --fstype ext4 --size=200 --asprimary

part / --fstype ext4 --size=102400

part swap --size=16384

part /data --fstype ext4 --size=100 --grow

reboot

%packages

@core

@server-policy

@workstation-policy

%end

8.修改显示界面

#vim /var/lib/tftpboot/pxelinux.cfg/default

DEFAULT menu

PROMPT 0

MENU TITLE Cobbler | http://www.cobblerd.org/

append initrd=/images/mirrtalk-6.5-x86_64/initrd.img ksdevice=bootif lang= kssendmac text ks=http://192.168.5.132/cblr/svc/op/ks/profile/mirrtalk-6.5-x86_64

ipappend 2

MENU end

重启相关服务

#/etc/init.d/xinetd restart

#/etc/init.d/cobblerd restart

指定某个profile的ks文件

#cobbler profile add --name=mirrtalk-6.5-x86_64 kickstart=/var/lib/cobbler/kickstarts/mirrtalk65miso.ks

#cobbler profile edit --name=mirrtalk-6.5-x86_64 kickstart=/var/lib/cobbler/kickstarts/mirrtalk65miso.ks

9.重启

#/etc/init.d/cobblerd restart
