Installing Kernel Headers for 2.6.31-302-rs

If you are wishing to compile kernel modules or other software you may be required to install the kernel headers on your Cloud Server. By default the kernel modules are not installed to save space and are not typically used by most software.

This tutorial will walk you through installing them on a Cloud Server. This tutorial assumes you logged in as the root user. Note that this tutorial has been tested on Ubuntu and CentOS-based distributions -- others have not been tested and may vary slightly.

Download Header Files

The first thing we will need to do is download the header files from Ubuntu, where our kernel originates from. To do that, run the following commands:

$ cd /
$ wget 
$ wget 

Note that the file names are a bit long so you will need to copy and paste them. Be sure that you are located in the root of the filesystem by running the cd / command!

Unpack Header Files

Now we need to use a program called ar to unpack the Debian .deb files in CentOS. Run the following commands to unpack the files and perform cleanup functions:

$ ar x linux-headers-2.6.31-302-ec2_2.6.31-302.7_amd64.deb data.tar.gz; tar -zxvf data.tar.gz; rm -f data.tar.gz
$ ar x linux-headers-2.6.31-302_2.6.31-302.7_all.deb data.tar.gz; tar -zxvf data.tar.gz; rm -f data.tar.gz  

Note once again that these commands are a bit long so you may need to copy and paste them.

Symbolic Link

Now we need to perform the final step of symbolically linking our newly unpacked headers to the correct directory. To do this simply run the following commands:

$ cd /usr/src
$ ln -s linux-headers-2.6.31-302-ec2 linux

You can verify that it worked by typing ls and you should see something similar to the following:

linux -> linux-headers-2.6.31-302-ec2

Now you are ready to compile your software!
