(f) /etc/xinetd.d/tftp 설정
# default: off

3. Client Node 설치
(a) BIOS에서 booting 순서 변경
– PXE Boot
– CD-ROM
– HDD
(b) reboot client node system
(c) 설치 완료 후 서버에서 tftp 서비스 종료
#chkconfig –level 3 tftp off
(d) /etc/dhcpd.conf 에서 다음 주석처리
# next-server 192.168.201.1;
# filename “pxelinux.0”;
(e) 클라이언트 재부팅
(f) 각 노드에서 다음의 명령 수행
# mount -t nfs 192.168.201.1:/tftpboot/linux-install /tftpboot/linux-install
# tar xvfP /tftpboot/linux-install/config/cluster-config.tar
# rm -f /etc/rc.d/rc3.d/*
# tar xvfP /tftpboot/linux-install/config/rc.tar (이때 주의사항 rsh, rlogin은 이걸로 안됨, xinetd.d/rsh, rlogin 복사)
(g) /etc/sysconfig/network-script/ifcfg-eth0, /etc/sysconfig/network-script/ifcfg-eth1 수정
(이때 mac address를 보존하고 수정해야함)
(h) reboot
