build nginx fast server on Centos 7

Hello.
I need someone with experience in nginx, vps and wordpress.
I have a vps server with Centos 7.2 minimal and i need someone to put nginx and
everything else it needs.
Then i need to optimize it for speed and stability.
but first of all i have my site with nginx on a server that has problem with the cart.
And it needs to be fixed before we start setting up the new vps.

Thank you !
