PREPARE SYSTEM INSTALL FILE FROM CD TO APACHE

# 安装web服务器，并把安装光盘内容复制到web服务器的网站目录
yum install -y httpd
mount /dev/cdrom /mnt
cp -rf /mnt/* /var/www/html

INSTALL “TFTP” & START SERVICE “XINETD”

yum -y install tftp tftp-server
vi /etc/xinetd.d/tftp
*****************************************************************
# default: off
# description: The tftp server serves files using the trivial file transfer \
#       protocol.  The tftp protocol is often used to boot diskless \
#       workstations, download configuration files to network-aware printers, \
#       and to start the installation process for some operating systems.
service tftp

PREPARE PXE BOOT DIRECTORY

# install syslinux first
yum -y install syslinux
 
# copy file to tftpboot directory
cp /usr/share/syslinux/pxelinux.0 /tftpboot/

# 某些教程是/usr/lib/syslinux/pxelinux.0具体情况可以利用find来查询
cp /data/www/images/pxeboot/{initrd.img,vmlinuz} /tftpboot/

# 每个版本的pxeboot里的内容可能会有些微的不同，请根据自己实际情况复制
cp /data/www/isolinux/boot.msg /tftpboot/
mkdir /tftpboot/pxelinux.cfg
cd /tftpboot/pxelinux.cfg/
cp /data/www/isolinux/isolinux.cfg /tftpboot/pxelinux.cfg/default

DHCP

yum -y install dhcp
cp /usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample /etc/dhcpd.conf
