I have a HP microserver proliant gen 8, and i want to know if there’s a way to make this hardware work as NAS with freeNAS … etc, and in the same time make it work as a web server with Centos Nginx ? please describe in steps.
Sure, but rather than attempting to virtualize on such limited hardware, I’d suggest just running CentOS to handle both functions. There’s probably no reason to use FreeNAS here, as CentOS can serve as a NAS and is entirely capable of ZFS.
This would be the best use of the resources available to your ProLiant Microserver.
