PXE Boot

Installation experiments Oracle Linux 8 and 9 using PXE (Boot, UEFI) and Kickstart. PXE-Server was deployed on Oracle Linux 8.10 In all configs:

• 10.1.1.1 is the PXE Server address
• /var/lib/tfpboot - folder with boot files
• /var/lib/tfpboot/images - folder with system installation files.

Setting:

1. Install packages. Configuring firewall.

dnf install -y dhcp-server filewalld rsync tftp-server xinetd syslinux nginx 
firewall-cmd --permanent --add-service=dhcp
firewall-cmd --permanent --add-service=tftp
firewall-cmd --permanent --add-service=http

2. Configuring dhcp

• Copy the file from the repository /src/etc/dhcp/dhcpd.conf to /etc/dhcp/dhcp.conf

3. Configuring tftp.

• Copy the file from the repository /src/etc/xinetd.d/tftp to /etc/xinetd.d/tftp

4. Setting up boot files::

• Copy the file from the repository /src/var/lib/tfpboot to /var/lib/tfpboot

5. Copy installation files from ISO.

# For Oracle Linux 8
mount -o loop /dev/cdrom /mnt
rsync -av /mnt/. /var/lib/tfpboot/images/ol8/
umount /mnt

# For Oracle Linux 9
mount -o loop /dev/cdrom /mnt
rsync -av /mnt/. /var/lib/tfpboot/images/ol9/
umount /mnt

6. Configuring kickstart for PXE:

• Copy the file from the repository /src/var/lib/tfpboot/ol8/ks.cfg to /var/lib/tfpboot/ol8/ks.cfg
• Copy the file from the repository /src/var/lib/tfpboot/ol9/ks.cfg to /var/lib/tfpboot/ol9/ks.cfg

7. Making a symbolic link for nginx:

ln -s /var/lib/tftpboot/images /usr/share/nginx/html/

8. Enable services and reboot:

systemctl enable nginx
systemctl enable dhcpd
systemctl enable xinetd
reboot
