session原理总结

This quick guide will show you how to compile and install a kernel from kernel.org in Fedora 14.

Start

Open a terminal and work through the below list of commands
. Modify where appropriate.

Install the following packages

su -c 'yum install rpmdevtools yum-utils gcc make ncurses-devel'

Setup your build environment

rpmdev-setuptree

Download and extract your Kernel source

cd ~/rpmbuild/SOURCES

wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.37 .tar.gz

tar -xf linux-2.6.37
.tar.gz

Configure and Compile it

cd linux-2.6.37

make menuconfig

export CONCURRENCY_LEVEL=3

time make rpm

General rule for concurrency level = number of processor cores + 1

Install it

cd ~/rpmbuild/RPMS/x86_64

su -c 'rpm -ivh --force kernel-2.6.37
-1.x86_64
.rpm'

cd /boot

su -c 'mkinitrd initramfs-2.6.37
.img 2.6.37
'

su -c 'vi grub/grub.conf'

Fedora 32-bit users replace x86_64
with i386

Edit your grub.conf file and add an entry for your new kernel. Just copy your first kernel entry and modify it.

Note: Please do not copy this grub.conf, it is for illustrative purposes only.

# grub.conf generated by anaconda

#

# Note that you do not have to rerun grub after making changes to this file

# NOTICE:  You do not have a /boot partition.  This means that

#          all kernel and initrd paths are relative to /, eg.

#          root (hd0,0)

#          kernel /boot/vmlinuz-version ro root=/dev/sda1

#          initrd /boot/initrd-[generic-]version.img

#boot=/dev/sda1
