15.自定义kickstart文件

[root@node2 ~]# cd /var/lib/cobbler/kickstarts/

[root@node2 kickstarts]# cp sample_end.ks CentOS6.ks

[root@node2 kickstarts]# vim centos6.ks

# kickstart template for Fedora 8 and later.

# (includes %end blocks)

# do not use with earlier distros

#platform=x86, AMD64, or Intel EM64T

# System authorization information

auth --useshadow --enablemd5

# System bootloader configuration

bootloader --location=mbr

# Partition clearing information

clearpart --all --initlabel

# Use text mode install

text

# Firewall configuration

firewall --service=ssh

# Run the Setup Agent on first boot

firstboot --disable

# System keyboard

keyboard us

# System language

lang en_US

# Use network installation

url --url=$tree

# If any cobbler repo definitions were referenced in the kickstart profile, include them here.

$yum_repo_stanza

# Network information

$SNIPPET('network_config')

# Reboot after installation

reboot

#Root password

rootpw --iscrypted $default_password_crypted

# SELinux configuration

selinux --disabled

# Do not configure the X Window System

skipx

# System timezone

timezone --utc Asia/Shanghai

# Install OS instead of upgrade

install

# Clear the Master Boot Record

zerombr

# Allow anaconda to partition the system as needed

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

part / --fstype=ext4 --size=10000

part /data --fstype=ext4 --size=5000

part swap --size=1000

%pre

$SNIPPET('log_ks_pre')

$SNIPPET('kickstart_start')

$SNIPPET('pre_install_network_config')

# Enable installation monitoring

$SNIPPET('pre_anamon')

%end

%packages

@chinese-support

@development

$SNIPPET('func_install_if_enabled')

%end

%post

$SNIPPET('log_ks_post')

# Start yum configuration

$yum_config_stanza

# End yum configuration

$SNIPPET('post_install_kernel_options')

$SNIPPET('post_install_network_config')

$SNIPPET('func_register_if_enabled')

$SNIPPET('download_config_files')

$SNIPPET('koan_environment')

$SNIPPET('RedHat_register')

$SNIPPET('cobbler_register')

# Enable post-install boot notification

$SNIPPET('post_anamon')

# Start final steps

$SNIPPET('kickstart_done')

# End final steps

%end

16.将自定义的kickstart文件与镜像相关联

[root@node2 ~]# cobbler profile edit --name=CentOS-6.4-x86_64 --distro=CentOS-6.4-x86_64 --kickstart=/var/lib/cobbler/kickstarts/centos6.ks

[root@node2 ~]# cobbler report

注，上面部分省略。

profiles:

==========

TFTP Boot Files : {}

Comment :

17.同步一下

*** TASK COMPLETE ***

18.新建客户端虚拟机

19.启动客户端并进行系统安装

(1).选择 “CentOS-6.4-x86_64”进行安装。

(2).选择后直接回车进行安装。

(3).开始安装初始化

(4).安装相关软件包

(5).软件包安装完成，大概过1分钟后进行重启

(6).重新启动虚拟机客户端

(8).进入登录界面

20.下面我们对客户端安装系统进行登录测试并查看

(1).输入用户名root与密码123456进行登录测试

(2).查看自定义的分区与时区

好了，到这里我们Linux运维自化工具之Cobbler工具就全部讲解完成了。
