HOWTO : Bootless with Ksplice Uptrack on Ubuntu Server 11.04

With Ksplice Uptrack, your Ubuntu Server is not required to reboot when the kernel is updated or upgraded. It makes your servers up to almost 99,99% uptime.

Step 1 :

Go to the following link and get your access key.
Get Ksplice Uptrack Access Key

Step 2 :

nano /etc/apt/sources.list.d/ksplice.list

Add the following lines to the file ksplice.list.

deb natty ksplice
deb-src natty ksplice

Step 3 :
Replace INSERT_ACCESS_KEY with your access key. Please use the same
access key for all of your systems:

sudo apt-get install ca-certificates
wget -N
sudo apt-key add ksplice-archive.asc
echo 'uptrack uptrack/accesskey string INSERT_ACCESS_KEY' | sudo debconf-set-selections
sudo apt-get update
sudo apt-get install uptrack

Step 4 :

nano /etc/uptrack/uptrack.conf

Change the following as is :
autoinstall = yes

Step 5 :

uptrack-upgrade -y

Remarks :

Ksplice Uptrack updates your running kernel in memory only. Enabling autoinstall does not mean the Uptrack client itself is automatically upgraded. You will be notified via e-mail when a new Uptrack client is available, and it can be upgraded through your package manager.

uptrack-upgrade -y

That's all! See you.
