How to move a compiled kernel to productive linux server ??

td0l2 · 07-21-2004, 04:07 AM

Hi all,

I have compiled a new 2.6.7 kernel and worked in a 2.4G linux server. Now, i want to transfer this new kernel to a slow debian linux server which is using 2.4.18 kernel. ( My 2.4G linux server is running RedHat 7.2 )
What kind of things do I need to concern ??
What package do i need to install ??

copy it over to the new box, alter the lilo.conf to accomodate the new kernel. that should be all you need to do.

From the machine you compiled the kernel from, use

Code:

make-kpkg kernel_image

to create a debianized package of your compiled kernel. make-kpkg is part of kernel-package. If you have already removed the sources, then do as Frustin suggested.

Take a look at this: http://www.cs.utexas.edu/users/suriy...migration.html

It provides information on some issues when upgrading from the 2.4.x kernel to the 2.6.x kernel.

In my case, the PS/2 mouse would not work and X failed to load (but maybe you don't need X?). You have to add the lines "psmouse" and "mousedev" to /etc/modules to make sure the PS/2 mouse works.

You also need to make sure you created an initrd for the kernel and add an initrd line to your bootloader. The initrd is created with the command: "make-kpkg --initrd kernel_image" The resulting .deb file can be copied to your other machine and installed with dpkg -i.

I wrote a summary of my experiences upgrading here: http://www.linuxquestions.org/questi...hreadid=206992

Thanks for your repy !

I just copy the kernel to /boot and change the lilo.conf in production server. The new kernel works but the modules can't load.

Then, i install "modules_init_tools" to upgrade "depmod, insmod..." but the situation is still the same. I just manually type "insmod 8139too", it replies some error message to me !! :-(

"ismod : error inserting modules "8139too" : -1 invalid module format

Please help to fix this problem.

Don't copy the kernel image to /boot. Copy the .deb file and install it with "dpkg -i <filename>.deb" The installation will create modules for the kernel.

Oh !! I do that for red hat which works for me. Why does debian need to install package rather than installing individual file or tar ball ??

I just ".configure" for modules_init_tools by using tar ball. It works !!
