#!/bin/bash

[ -d /data/yum/ ] || mkdir -p /data/yum/
mv   /etc/yum.repos.d/* /data/yum/
rm -rf /etc/yum.repos.d/*
echo [rhel-data] >/etc/yum.repos.d/rhel-source.repo
echo name=RHEL5 data >> /etc/yum.repos.d/rhel-source.repo
echo baseurl=file:///media/Server >>/etc/yum.repos.d/rhel-source.repo
echo enabled=1 >> /etc/yum.repos.d/rhel-source.repo
echo gpgcheck=0 >> /etc/yum.repos.d/rhel-source.repo

vim /root/yum.sh
#!/bin/bash
umount /dev/cdrom
mount /dev/cdrom  /media

bash /root/yumresoure.sh
bash /root/yum.sh

二、安装kickstart服务
yum install -y system-config-kickstart.noarch
system-config-kickstart

三、安装httpd服务
yum install -y httpd

mkdir /var/www/html/rhel5.9
cp -r /media/* /var/www/html/rhel5.9/
cp /root/ks.cfg /var/www/html/rhel5.9/

vim /var/www/html/rhel5.9/ks.cfg

四、安装xinetd和tftp服务
vim /etc/xinetd.d/tftp
yum install -y tftp xinetd
service tftp
{
        socket_type             = dgram
        protocol                = udp
        wait                    = yes
        user                    = root
        server                  = /usr/sbin/in.tftpd
        server_args             = -s /tftpboot
        disable                 = no           ####默认是yes，需修改为no
        per_source              = 11
        cps                     = 100 2
        flags                   = IPv4
}
cp /usr/share/syslinux/pxelinux.0 /tftpboot/
cp /media/p_w_picpaths/pxeboot/initrd.img /tftpboot/
cp /media/p_w_picpaths/pxeboot/vmlinuz  /tftpboot/
cp /media/isolinux/*.msg   /tftpboot/
mkdir  pxelinux.cfg
cp /media/isolinux/isolinux.cfg  /tftpboot/pxelinux.cfg/isolinux.cfg
mv  /tftpboot/pxelinux.cfg/isolinux.cfg  /tftpboot/pxelinux.cfg/default
vim /tftpboot/pxelinux.cfg/default
default linux
prompt 1
timeout 60
display boot.msg
F1 boot.msg
F2 options.msg
F3 general.msg
F4 param.msg
F5 rescue.msg
label linux
  kernel vmlinuz
  append initrd=initrd.img ks=http://10.10.10.30/rhel5.9/ks.cfg

五、安装dhcpd服务
yum install -y dhcpd
cp /usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample /etc/dhcpd.conf
vim /etc/dhcpd.conf
#
# DHCP Server Configuration file.
#   see /usr/share/doc/dhcp*/dhcpd.conf.sample  
#
dDNS-update-style interim;
ignore client-updates;
next-server 10.10.10.30;
filename "/pxelinux.0";
subnet 10.10.10.0 netmask 255.255.255.0 {

# --- default gateway
        option routers                  10.10.10.30;
        option subnet-mask              255.255.255.0;

#       option nis-domain               "domain.org";
#       option domain-name              "domain.org";
#       option domain-name-servers      192.168.1.1;

        option time-offset              -18000; # Eastern Standard Time
#       option ntp-servers              192.168.1.1;
#       option netbios-name-servers     192.168.1.1;
# --- Selects point-to-point node (default is hybrid). Don't change this unless
# -- you understand Netbios very well
#       option netbios-node-type 2;

        range dynamic-bootp 10.10.10.200 10.10.10.240;
        default-lease-time 21600;
        max-lease-time 43200;

        # we want the nameserver to appear at a fixed address
#       host ns {
#               next-server marvin.redhat.com;
#               hardware ethernet 12:34:56:78:AB:CD;
#               fixed-address 207.175.42.254;
#       }
