Step 1: Download the Ubuntu 14.04 LiveCD, mount it on the server (through iKVM or using a burned CD/DVD) and boot the server from the media
Step 2: At the welcome screen select "Try Ubuntu"
Step 3: Open a terminal window (the application name is Terminal)
Step 4: Make yourself root
sudo su -
Step 5: Install curl using:
apt-get install curl
Step 6: Run the benchmark
bash <(curl -sk http://linux-bench.com/linux-bench.sh)
At the end of the run you will see a line that says "ref_link" and has a number next to it. You can use that ID number on http://linux-bench.com/parser.html and it will display benchmark results in a formatted web page. You can then share that ref_link with friends.
As root/ super user (sudo su -) type:
bash <(curl -sk http://raw.githubusercontent.com/STH-Dev/linux-bench/master/linux-bench.sh)
chmod +x linux-bench.sh
