this article is touches on some problems with cent os & nodejs in development mode, but really is going in detail about the two in hosting & deploying -- specifically --

""" Just like on your development machine you can run node app.js on your server and your code will be executed perfectly.

However, this is far from ideal and there are many problems with it. Let’s look at just a few of them.

Serving static files, like JavaScript, images & CSS, can be done with node but it is not very efficient. It will use too much memory and it might not cache frequently accessed files, which in result can make your Node app slow or even crash it. """

The Installing Node.js via package manager page has a nice page with specific sections about
CENT OS

[personal opinion]

I think from what i searched is, there isn't a plethora amount of nodejs & cent os experience going on
but i'm sure you will find enough to get by to fix your problems.
