Hello I'm looking at changing my PHP handler from fast CGI to FPM to take full advantage of NGINX, not experienced in this side of things, but from my limited research it can offload strain on the server and improve speed. What would be the best way for me to do this? server is CentOS7 running plesk. I tried simply switching it over in plesk, and got met with a 404 anytime I clicked a forum. Suffice to say I reversed it.
