Rootserver kernel upgrading

April 10, 2008 in linux, operating systems | No comments

Connect to your server via ssh and then download the latest kernel version. Best practice is to look first via ftp for the correct file.

Type within your terminal:

ftp update.onlinehome-server.com
User: anonymous
Password: guest
cd local-updates/kernel/deb/
ls
exit

The filename of the latest version is: linux-image-2.6.27.4-20081028a_rootserver.1_amd64.deb
Let’s download this version:

wget ftp://update.onlinehome-server.com/local-updates/kernel/deb/linux-image-2.6.27.4-20081028a_rootserver.1_amd64.deb

Now we have to install the kernel by the following command.

dpkg --install linux-image-2.6.27.4-20081028a_rootserver.1_amd64.deb

Either you check the pointer of vmlinuz to your new kernel in /boot/

ln -sf /boot/vmlinuz-2.6.27.4-20081028a /boot/vmlinuz

Please replace vmlinuz-2.x.y.z by the release you want to add!

or you change /boot/grub/menu.lst accordingly. For the above mentioned kernel it has to look somehow like this:

serial –unit=0 –speed=57600
terminal –timeout=10 serial console

default=0
timeout=5

title linux with serial console
root (hd0,0)
kernel /boot/vmlinuz-2.6.27.4-20081028a ro root=/dev/md1 console=tty0 console=ttyS0,57600

title linux.old
root (hd0,0)
kernel /boot/vmlinuz.old ro root=/dev/md1 console=tty0 console=ttyS0,57600
