[가상머신] PXE 설치서버 실습

 

1) Server에서 dnf -y install dhcp-server tftp-server vsftpd

    ㄴ dhcp, tftp, ftp 설치

 

 

2) vi /etc/dhcp/dhcpd.conf

 

subnet 192.168.111.0 netmask 255.255.255.0

{

option routers 192.168.111.2;

option subnet-mask 255.255.255.0;

range dynamic-bootp 192.168.111.120 192.168.111.199;

option domain-name-servers 192.168.111.2;

allow booting;

allow bootp;

next-server 192.168.111.130;

filename “pxelinux.0”;

}

 

3) vi /etc/vsftpd/vsftpd.conf

12번째 행 no를 yes로

 

4) umount /dev/cdrom

5) mount /dev/cdrom /var/ftp/pub/

 

6)

cp /var/ftp/pub/images/pxeboot/vmlinuz /var/lib/tftpboot/

cp /var/ftp/pub/images/pxeboot/initrd.img /var/lib/tftpboot

cp /var/ftp/pub/isolinux/ldlinux.c3s /var/lib/tftpboot

 

 

7)

cd /usr/share >> mkdir syslinux

 

8) cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/

 

9) vi

 

DEFAULT CentOS8_Auto_Install

 

LABEL CentOS8_Auto_Install

    kernel vmlinuz

    APPEND initrd=initrd.img repo=ftp://192.168.111.130/pub

 

 

10) systemctl restart dhcpd, vsftpd, tftp

      systemctl enable dhcpd, vsftpd, tftp

 

 

11) Test 가상 머신 생성

RAM 2GB

하드디스크, cd롬 삭제

하드디스크 추가(SCSI, 20GB single file)

 

 

12) Server 방화벽 설정 필요!

 

 

일단 수업때는 편의상 그냥 방화벽 꺼버림.
