10 Aggiungi CentOS 4.4 Netboot

Successivamente, scarichiamo i file netboot di CentOS 4.4 e li mettiamo in /var/lib/tftpboot/centos/4.4 in questo modo:

cd /var/lib/tftpboot
mkdir -p centos/4.4/i386
cd centos/4.4/i386
wget http://ftp-stud.fht-esslingen.de/pub/Mirrors/centos/4.4/os/i386/images/pxeboot/initrd.img
wget http://ftp-stud.fht-esslingen.de/pub/Mirrors/centos/4.4/os/i386/images/pxeboot/vmlinuz

(Puoi scaricare i file anche da qualsiasi altro mirror di CentOS. Usa uno che sia vicino a te.)

Poi aggiungi una sezione LABEL per CentOS 4.4 a /var/lib/tftpboot/pxelinux.cfg/default. Il file dovrebbe ora apparire così:

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

Quando installi CentOS 4.4 tramite rete, l’installer ti chiederà il metodo di installazione. Seleziona HTTP e inserisci ftp-stud.fht-esslingen.de come host, pub/Mirrors/centos/4.4/os/i386/ come directory. Naturalmente, puoi usare anche qualsiasi altro mirror di CentOS; usa uno che sia vicino a te.
