KickStart / PXE 기본 설치(NFS)

DHCP 서버

# yum -y install dhcp-server
혹은
# dnf install dhcp-server

DHCP 서버 설정 파일

• Legacy(BIOS) 모드 에서는 pxelinux.0 파일 사용
• UEFI 모드에서는 grubx64.efi 사용
• 아이피 대역대에 따라서 ip 수

# vi /etc/dhcp/dhcp.conf
----------------------------------------------------------------------------------------
#
# DHCP Server Configuration file.
#   see /usr/share/doc/dhcp-server/dhcpd.conf.example
#   see dhcpd.conf(5) man page
#
dhcp_interface="eth0";

subnet 192.168.203.0 netmask 255.255.255.0 {
     option routers 192.168.203.1;
     option subnet-mask 255.255.255.0;
     range dynamic-bootp 192.168.203.33 192.168.203.38;
     default-lease-time 3600;
     max-lease-time 7200;
     ### pxe setting ###
     allow booting;
     allow bootp;
     next-server 192.168.203.1;
     # filename "pxelinux.0";
     # filename "grubx64.efi";
}

TFTP-Server

# yum -y install[dnf install] tftp-server
# cp /usr/lib/systemd/system/tftp.service /etc/systemd/system/tftp-server.service
# cp /usr/lib/systemd/system/tftp.socket /etc/systemd/system/tftp-server.socket

파일 복사 후 변경된 경로에서 제대로 동작하기 위해 파일을 아래처럼 수정

# vi /etc/systemd/system/tftp-server.service
----------------------------------------------------------------------------------------

데몬 재시작

# systemctl restart tftp-server

syslinux 설치

# dnf install syslinux

부팅에 필요한 파일 복사

cp /usr/share/syslinux/menu.c32 /var/lib/tftpboot/
cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/
cp /usr/share/syslinux/ldlinux.c32 /var/lib/tftpboot/
cp /usr/share/syslinux/libutil.c32 /var/lib/tftpboot/

PXE 구성 파일 설정

• NFS , FTP 마지막으로 설정한 경로에 따라 레파지토리 경로 설정이 다르니 유의!!

# mkdir /var/lib/tftpboot/pxelinux.cfg
----------------------------------------------------------------------------------------

# vi /var/lib/tftpboot/pxelinux.cfg/default
----------------------------------------------------------------------------------------

로컬 레포지 토리 생성

NFS 설치

# dnf -y install nfs-utils

NFS 설정파일 (경로 설정)

vi /etc/exports

Kickstart 경로 생성 및 부팅 파일 복사

mkdir -p /var/lib/tftpboot/{kickstart,pxelinux.cfg,rocky8.6}

#kickstart , pxelinux.cfg , rocky8.6 디렉토리 생성

mount Rocky86.dvd /mnt
#OS 마운트

cp -R * /mnt/. /var/libtftpboot/rocky8.6
#/mnt -> /var/lib/tftpboot/rocky8.6 이미지 복사

cp /usr/share/syslinux/menu.c32 /var/lib/tftpboot/
