![[HOWTO] 2.4.21 Kernel upgrade from source on DELL Xeon](https://www.webhostingtalk.com/images/wht_smilies/cool.gif)
I did it yesterday and posted the same howto on rackshack forum
1) cd /usr/src
2) wget http://kernel.org/pub/linux/kernel/v...2.4.21.tar.bz2
3) wget http://kernel.org/pub/linux/kernel/v...2.4.22-rc2.bz2
4) bzcat linux-2.4.21.tar.bz2 | tar xv
5) ln -s linux-2.4.21 linux
6) cd /usr/src/linux
7) bzip2 -dc /usr/src/patch-2.4.22-rc2.bz2 | patch -p1 --dry-run
8)
wget http://64.246.63.172/conf.txt <---- config file
mv conf.txt .config
make dep
make clean
make bzImage
make modules
make modules_install
cp System.map /boot/System.map-2.4.21
cp arch/i386/boot/bzImage /boot/vmlinuz-2.4.21
cd /boot
ln -sf System.map-2.4.21 System.map
ln -sf vmlinuz-2.4.21 vmlinuz
9) My server use LILO!, if your boot loader - grub, feel free to ask.
edit /etc/lilo.conf
**** add following lines:
image=/boot/vmlinuz-2.4.21
label=newlinux
read-only
root=/dev/sda3
10) /sbin/lilo
11) To test your boot run
/sbin/lilo -R newlinux
**** it will be one-time boot, so if anything is wrong, request to reboot the server and old kernel will be loaded
My /etc/lilo.conf:
prompt
timeout=50
default=linux
boot=/dev/sda
map=/boot/map
install=/boot/boot.b
message=/boot/message
linear
image=/boot/vmlinuz-2.4.18-27.7.xsmp
label=linux
initrd=/boot/initrd-2.4.18-27.7.xsmp.img
read-only
root=/dev/sda3
image=/boot/vmlinuz-2.4.18-27.7.x
label=linux-up
initrd=/boot/initrd-2.4.18-27.7.x.img
read-only
root=/dev/sda3
image=/boot/vmlinuz-2.4.21
label=newlinux
read-only
root=/dev/sda3
12) /sbin/shutdown -r now
13) If everything is ok, update lilo.conf :
prompt
timeout=50
default=newlinux
boot=/dev/sda
map=/boot/map
install=/boot/boot.b
message=/boot/message
linear
image=/boot/vmlinuz-2.4.18-27.7.xsmp
label=linux
initrd=/boot/initrd-2.4.18-27.7.xsmp.img
read-only
root=/dev/sda3
image=/boot/vmlinuz-2.4.18-27.7.x
label=linux-up
initrd=/boot/initrd-2.4.18-27.7.x.img
read-only
root=/dev/sda3
image=/boot/vmlinuz-2.4.21
label=newlinux
read-only
root=/dev/sda3
14) /sbin/lilo
Output:
Added newlinux * <-------- default kernel
Added linux
Added linux-up
15) /sbin/shutdown -r now
16) uname -a
Linux tiger.--------.---- 2.4.21 #1 SMP Tue Aug 19 22:31:52 CDT 2003 i686 unknown
