I use Debian 7.5 with dotdeb repos.
I followed this guide: https://rtcamp.com/wordpress-nginx/tutorials/single-site/fastcgi-cache-with-purging/
And tested with this: https://rtcamp.com/tutorials/nginx/upstream-cache-status-in-response-header/
I always get BYPASS in my headers and cache details are not shown in the source of any pages and I have verified it is turned on in the wp-admin. The cache dir in /var/run/nginx-cache is always empty. I turned on logging but thelogs are empty. No errors in my nginx log either. Am really confused what could be the issue!
Seems like nginx-cache-purge is installed :
# nginx -V 2>&1 | grep nginx-cache-purge -o
nginx-cache-purge
My nginx virtual host file:
#move next 4 lines to /etc/nginx/nginx.conf if you want to use fastcgi_cache across many sites
fastcgi_cache_path /var/run/nginx-cache levels=1:2 keys_zone=WORDPRESS:100m inactive=60m;
fastcgi_cache_key "$scheme$request_method$host$request_uri";
