12ewe

                      1 环境准备
  centos 6.4 x86_64 安装图形界面 以运行sysconfig-config-kickstart
  yum install vim ntp man
  yum groupinstall “development tools” “server platform development” “desktop platform development”
  关闭 iptables selinux
  
    2 挂载镜像文件
  mkdir /media/cdrom
  mount /dev/cdrom /media/cdrom
  
    3安装所需要的软件包
  yum install dhcp xinetd tftp-server nfs* httpd syslinux system-config-kickstart
  
    4 配置dhcp服务器
  cp /usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample /etc/dhcp/dhcpd.conf
  vim /etc/dhcp/dhcpd.conf
  # option definitions common to all supported networks...   
option domain-name "example.org";     
option domain-name-servers 192.168.200.2;
  default-lease-time 600;   
max-lease-time 7200;
  # Use this to enble / disable dynamic dns updates globally.   
ddns-update-style none;
  # If this DHCP server is the official DHCP server for the local   
# network, the authoritative directive should be uncommented.     
#authoritative;
  # Use this to send dhcp log messages to a different log file (you also   
# have to hack syslog.conf to complete the redirection).     
log-facility local7;
  next-server 192.168.200.131;   
filename="pxelinux.0";     
#No service will be given on this subnet, but declaring it helps the     
# DHCP server to understand the network topology.
  subnet 192.168.200.0 netmask 255.255.255.0 {   
range 192.168.200.10 192.168.200.20;     
option routers 192.168.200.2;     
}
  
    5 复制安装系统需要的核心文件及光盘镜像
  cd /media/cdrom/isolinux/
  cp vmlinuz initrd.img boot.msg splash.jpg /var/lib/tftpboot/
  cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/
  mkdir /var/lib/tftpboot/pxelinux.cfg/
  cp /media/cdrom/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default
  
    6 编辑default文件
  vim /var/lib/tftpboot/pxelinux.cfg/default
  label linux   
menu label ^Install or upgrade an existing system     
menu default     
kernel vmlinuz     
append initrd=initrd.img ramdisk_size=8192 ks=http://192.168.200.131/ks.cfg
  
    7 配置NFS 服务器
  Vim /etc/exports
  /media/cdrom 192.168.200.0/255.255.255.0 (ro,sync)
  
    8 启动httpd nfs xinetd tftp 服务
  service httpd start
  service dhcpd start
  service rpcbind start
  service nfs start
  service xinetd start
  chkconfig httpd on
  chkconfig dchpd on
  chkconfig rpcbind on
  chkconfig nfs on
  chkconfig tftp on
  
    9 在图形界面运行system-config-kickstart （过程略）
  创建ks.cfg文件 移动到 /var/www/html

# Installation logging level     
logging --level=info     
# Reboot after installation     
reboot     
# System timezone

# Network information     
network --bootproto=dhcp --device=eth0 --onboot=on     
# System bootloader configuration     
bootloader --location=mbr     
# Clear the Master Boot Record     
zerombr     
# Partition clearing information     
clearpart --all
  %packages   
@desktop-platform-devel     
@development     
@server-platform-devel
  # Disk partitioning information   
part /boot --fstype="ext4" --size=500     
part / --fstype="ext4" --size=10000     
part swap --fstype="swap" --size=2000     
part /data --fstype="ext4" --grow --maxsize=1 --size=1
  磁盘分区如要使用LVM 可手工修改配置文件
