在SUSE linux上编译内核

How to compile the kernel manually, SUSE style!.
For this example, I’ll use the new kernel 3.11 (obviously) on a SLES11 SP3 server.
1. After all we need to install: ncurses-devel
# zypper install ncurses-devel
2. Get the source:
# wget "https://www.kernel.org/pub/linux/kernel/v3.x/linux-3.11.tar.xz"
3. Unpack the source:
# tar -Jxvf linux-3.11.tar.xz -C /usr/src/
4. Configure the kernel:
# cd /usr/src/linux-3.11/
Make sure you are in the path from the source
# make mrproper
If this is your first time, you really do not need this step, this only cleans .o files and other temporary
In the next step there are several ways to configure the kernel, I prefer to make menuconfig, but if you don’t have experience or want to play it safe, I recommend you use an existing configuration, to do this copy your old config file to the new source path:
# cp /boot/config-`uname -r` .config
If you still want to change or add something, at this point you can run: make menuconfig
HINT: After configuration you can further customize the kernel, adding a “extraversion” value. In the Makefile, edit the “EXTRAVERSION =” field, for (this) example:
注：如果你是从当前系统内核的源码编译，那么一定要修改这个，要不然在安装内核时会与原系统发生冲突。
VERSION = 3 PATCHLEVEL = 11 SUBLEVEL = 0 EXTRAVERSION = -w00t NAME = Linux for Workgroup
5. Build the Kernel:
# make rpm
Because we copy the old configuration in this step we ask about the new kernel features, read carefully before responding.
Now, take a break, this step will take a bit depending on the performance of your hardware.
6. Install the Kernel:
If all went well, you will see output similar to this:
[...] Wrote: /usr/src/packages/SRPMS/kernel-3.11.0_w00t_0.11_default-1.src.rpm Wrote: /usr/src/packages/RPMS/x86_64/kernel-3.11.0_w00t_0.11_default-1.x86_64.rpm Wrote: /usr/src/packages/RPMS/x86_64/kernel-headers-3.11.0_w00t_0.11_default-1.x86_64.rpm Executing(%clean): /bin/sh -e /var/tmp/rpm-tmp.13989 + umask 022 + cd /usr/src/packages/BUILD + cd kernel-3.11.0_w00t_0.11_default + rm -rf /var/tmp/kernel-3.11.0_w00t_0.11_default-root + exit 0 rm kernel-3.11.0_w00t_0.11_default.tar.gz kernel.spec
Install the new Kernel package under /usr/src/packages/RPMS/x86_64/:
# cd /usr/src/packages/RPMS/x86_64/
sp3-lab:/usr/src/packages/RPMS/x86_64 # ls kernel-3.11.0_w00t_0.11_default-1.x86_64.rpm kernel-headers-3.11.0_w00t_0.11_default-1.x86_64.rpm sp3-lab:/usr/src/packages/RPMS/x86_64 #
# rpm -ivh kernel-3.11.0_w00t_0.11_default-1.x86_64.rpm
And build the initrd
# mkinitrd
Now it only remains to edit the grub menu:
# vim /boot/grub/menu.lst
And add these lines, obviously putting the right disk to your existing system:
title SUSE Linux Enterprise Server 11 SP3 - 3.11 Linux for Workgroups root (hdX,X) kernel /boot/vmlinuz-3.11.0-w00t-0.11-default root=/dev/XXX resume=/dev/disk/XXX splash=silent crashkernel=256M-:128M showopts vga=0x314 initrd /boot/initrd-3.11.0-w00t-0.11-default
Basically, what we do here is copy the current grub entry in your system and just change the title and the image of the new Kernel.
Now, reboot!
We should see the new option in the grub.
