Upgrading kernel
Situation
the existing kernel was 2.4 and the required one is 2.6
cd /usr/local/src
wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.20.1.tar.gztar -zxf linux-2.6.20.1.tar.gz
cd linux-2.6.20.1
Now we need to copy the existing kernel configuration file
cp /boot/config-2.4.22-1.2199.nptlsmp /usr/local/src/linux-2.6.20.1/.config
Now we need to configure the kernel using this configuration file .. for that use
make oldconfig
You can see a lot of new features for the 2.6 kernel and select the ones we need .
Then to compile and install:
make bzImage
make modules
make modules_install
make install
Once it is installed we need to edit the boot loader (/etc/grub.conf) to load the new kernel . Reboot the server
