This is essentially the same as connecting your VPS to MetaTrader.
The steps are:
Sign-up for a plan with a VPS hosting company, we recommend New York City Servers
Once you are signed-up you will receive instructions to connect to the VPS server from your PC using Remote Desktop.
Once connected to your VPS, Install cTrader onto the VPS, start it and login with your credentials, create a demo or connect to your live account.
You should now be connected and ready to trade.
