Compiling a custom kernel on RedHat Enterprise

Compiling a custom kernel on RedHat Enterprise

Andrew P Myers : 25/05/2004

# The following commands can be used to compile a new

# linux kernel, e.g. to include IEEE1394 support.

# You will need to do this everytime there is a kernel update, so download and install these first. Then,

# Make a backup of /boot/grub.conf

cp /boot/grub.conf /boot/grub.conf.backup

cd /usr/src/linux-2.4.21-15.EL     # or whatever the latest kernel is

make mrproper

make config                 # yes to all (default = y = <enter>)

          # "make xconfig" needs to import initial config file - fiddly!

         # leda/dram=P4 ; castor/pollux=athlon

make dep

make clean

make bzImage

make modules

make modules_install        # populates /lib/modules – look for ieee1394

# Now install the new kernel in /boot

cp System.map /boot/System.map-2.4.21-15.ELcustom

cp arch/i386/boot/bzImage /boot/vmlinuz-2.4.21-15.ELcustom

cp .config /boot/config-2.4.21-15.ELcustom

cp vmlinux /boot/vmlinux-2.4.21-15.ELcustom

mkinitrd /boot/initrd-2.4.21-15.ELcustom.img 2.4.21-15.ELcustom

# Now edit /boot/grub/grub.conf to boot into new kernel.

vi /boot/grub/grub.conf

# Insert something like:

title Red Hat Enterprise Linux WS (2.4.21-15.EL with IEEE1394)

  root (hd0,0)

  kernel /vmlinuz-2.4.21-15.ELcustom ro root=LABEL=/ hda=ide-scsi

  initrd /initrd-2.4.21-15.ELcustom.img

# And change the default boot kernel ID in grub.conf

# Now reboot!!!
