best way to manage about 5 laravel website on vps?

i have a vps with 2Gb Ram and 1 Core cpu(2GHz), i can choose the OS, i chose ubuntu 16.04 and i could configure the LAMP and run one of my sites, but it was a little bit pain for me, i can install free Hosting CP on vps, but i dont think its neccessary for only few website.can any one give me clue how to manage them, consider that i havent enough knowledge in server configuratin and security of it.
