1. TFTP 구성
(페도라는 기본 /var/lib/tftpboot 디렉토리사용)
yum install tftp-server
2.1 vi /etc/xinet.d/tftpd (xinetd daemon) // RHEL 기준
disable = yes // ‘yes’ change ‘no’
# firewall-cmd --add-service=tftp // 방화벽을 사용한다면 이와 같이 설정
2.2 부팅 옵션 설정 파일을 생성
# mkdir /tftpboot/pxelinux.cfg
# touch /tftpboot/pxelinux.cfg/default
You now need the pxelinux.0 file from the SYSLINUX package in the ISO image file. To access it, run the following commands as root:
# mount -t iso9660 /path_to_image/name_of_image.iso /mount_point -o loop,ro
# cp -pr /mount_point/Packages/syslinux-version-architecture.rpm /publicly_available_directory
# umount /mount_point
Extract the package:
# rpm2cpio syslinux-version-architecture.rpm | cpio -dimv
Create a pxelinux/ directory within tftpboot/ and copy the pxelinux.0 file into it:
# mkdir /var/lib/tftpboot/pxelinux
# cp publicly_available_directory/usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/pxelinux
[root@theko tftpboot]# ls -al
