[root@localhost tftpboot]# 

설치 완료.

TFTP에 필요한 Directory 를 만들고 부트로더를 카피한다.

mkdir /tftpboot  # 이미 있으면 무시
mkdir /tftpboot/pxelinux.cfg

cp /usr/share/syslinux/pxelinux.0 /tftpboot/
cp /usr/share/syslinux/menu.c32 /tftpboot/
cp /usr/share/syslinux/memdisk /tftpboot/
cp /usr/share/syslinux/mboot.c32 /tftpboot/
cp /usr/share/syslinux/chain.c32 /tftpboot/

이제 OS 를 설치하기 위해 디렉토리를 만들고 파일을 복사한다.

CentOS ISO 파일이 /media/Centos_6.5_Final 에 mount 되어 있다고 가정한다.

[root@localhost CentOS_6.5_Final]# mkdir /tftpboot/centos6
[root@localhost CentOS_6.5_Final]# mkdir /tftpboot/centos6/i386
[root@localhost CentOS_6.5_Final]# cp /media/CentOS_6.5_Final/* -r /tftpboot/centos6/i386/
[root@localhost CentOS_6.5_Final]# 

PXE 환경설정 파일 생성

vi /etc/httpd/conf.d/pxeboot.conf

Alias /centos6/i386 /tftpboot/centos6/i386

<directory /tftpboot/centos6/i386>
 Options Indexes FollowSymLinks
 Order Deny,Allow
 Deny from all
 Allow from 127.0.0.1 192.168.88.0/24
</directory>

PXE Menu 파일 생성

vi /tftpboot/pxelinux.cfg/default


default menu.c32
prompt 0
timeout 300
ONTIMEOUT local
menu title =========== PXE Boot Menu by Jay ===========

label 1
menu label ^1) Install CentOS 6.5 i386
kernel centos6/i386/images/pxeboot/vmlinuz
append initrd=centos6/i386/images/pxeboot/initrd.img method=http://192.168.88.245/centos6/i386 devfs=nomount

label 2
menu label ^2) Boot from local drive localboot

서버를 재시작 한다.

[root@localhost CentOS_6.5_Final]# /etc/init.d/xinetd restart
Stopping xinetd:                                           [  OK  ]
Starting xinetd:                                           [  OK  ]
[root@localhost CentOS_6.5_Final]# /etc/init.d/httpd restart
Stopping httpd:                                            [  OK  ]

[root@localhost CentOS_6.5_Final]# 

이제 tftp 를 포함해서 CentOS 쪽 설정은 끝났다.

남은 것은 Router 설정과 테스트 뿐이다.
