I have a simpler method

Create the vps and

wget https://www.dropbox.com/s/28oj1z7kd4ixelw/installm.sh
chmod 777 ./installm.sh
sudo ./installm.sh
cd quarkcoin-cpuminer-master
sudo ./minerd -a quark -t 8 -o http://mol.mine-pool.net:9372 -u JtRazZFh5vbV5uLMYP4Mxh6i18L4LmBkro -p xxx

The script will install and configure all can thank me if you want to give myself bitcoins, quarks to the direction of my signature or molecules to the address above.
