yes I installed varnish and followed Nginx Wordpress + WP-FFPC Plugin + ngx_pagespeed - CentminMod.com LEMP Nginx web stack for CentOS guide.
I will try reinstall Wordpress - WP Cacher Enabler Plugin by KeyCDN folks guide.
and varnish is not good? remove?

 

ahh i can`t config. so just googling and ctrl v

ok thanks a lot. I will try again
