Extend your RAM by adding a swap file: [linux-add-a-swap-file-howto](http://www.cyberciti.biz/faq/linux-add-a-swap-file-howto/)

a swap file is a file stored on the computer hard drive that is used as a temporary location to store information that is not currently being used by the computer RAM. By using a swap file a computer has the ability to use more memory than what is physically installed in the computer [swapfile](http://www.computerhope.com/jargon/s/swapfile.htm)

In Short:

Login as root: su - or execute the commands with sudo in front

1. dd if=/dev/zero of=/swapfile1 bs=1024 count=524288

2. mkswap /swapfile1

3. chown root:root /swapfile1

4. chmod 0600 /swapfile1

5. swapon /swapfile1

Now the swap file will be activated temporarily, but will be gone after reboot. You should have enough RAM for your installing process

To Remove the File:

1. swapoff -v /swapfile1

2. rm /swapfile1
