Vježbe

Vježba 1. Instalacija nove jezgre

1. 
   Instalirajte potrebne pakete za prevođenje nove jezgre:
   

yum -y groupinstall 'Development tools'

yum -y install ncurses-devel rpm-build qt-devel

2. 
   Preuzmite izvorni kôd Linuxove jezgre:
   

cd /usr/src/kernels

wget https://www.kernel.org/pub/linux/kernel/v3.x/linux-3.12.6.tar.bz2

3. 
   Otpakirajte izvorni kôd:
   

tar xjf linux-3.12.6.tar.bz2

4. 
   Otiđite u direktorij /usr/src/linux-version i kopirajte staru konfiguracijsku datoteku config iz direktorija /boot u trenutni direktorij i nazovite ju .config.
   

cd /usr/src/kernels/linux-3.12.6

cp /boot/config-`uname –r` .config

5. 
   Pokrenite alat za konfiguraciju jezgre:
   

make menuconfig

make xconfig

6. 
   Snimite promjene u datoteku .config.
   
7. 
   Sada možete prevesti jezgru i module koristeći naredbu:
   

make

8. 
   Sada možete instalirati novoprevedenu jezgru i pripadajuće module koristeći sljedeće naredbe:
   

make modules_install

make install

Moduli se sada nalaze u direktoriju /lib/modules/version.

Nova jezgra se nalazi u datoteci bzImage u direktoriju /usr/src/kernels/linux-version/arch/x86/boot/.

9. 
   Sada možete urediti konfiguracijsku datoteku bootloadera GRUB:
   

vi /boot/grub/menu.lst

vi /boot/grub/grub.conf

Zamijenite redak default=1 u default=0.

Dodajte znak # na početak retka hiddenmenu.

10. 
    Ponovno pokrenite računalo.
