How to Compile Linux Kernel
Configure Yum Repository in local machine, So we can install following packages :-
# yum install kernel-header* redhat-rpm-config-* unidef* rpm-build*
# yum install ncurse* (for menuconfig)
# yum install gcc* (for gconfig)
# yum install qt* glibc* gtk* (for xconfig)
# useradd brewbuilder
# groupadd brewbuilder
# tar -xvf kernel-2.x.tar.gz
# cd kernel-2.x
# make menuconfig OR make gconfig OR make xconfig
# make (Build the actual kernel & modules)
# make modules_install (Installthe modules under /lib/modules/<kernel-version>)
# make install (Install the Kernel in/boot & adds a GRUB entry in the file)
Check grub entry in /etc/grub.conf file and Rrboot the machine with new compile kernel.
