Varnish doesn't seems to be doing anything

1

I would highly appreciate an input on whats going wrong here:

Running Magento on Ubuntu 14.04 x64 + Nginx + Mysql + Php5-FPM

Please double check my steps so maybe you could help me point what's messy:

Varnish is running on 8081 and Nginx on 8080.

The way I have setup Varnish/Magento with Turpentine before is like this:

Have varnish listen on port 80, nginx on any port (something like 8080)

Configure varnish to listen on port 80 in /etc/default/varnish.conf

Configure /etc/varnish/default.vcl and set backend to 8080 (which is set right now)

so the requests from internet will hit on Varnish and if it finds the static content in it's cache it won't go back to the nginx to process. It will simply deliver that content from it's cache.

The cache is set to store in RAM as it's set to malloc 256m means 256MB in RAM you can also store it's cache in Hard Disk in a file and size it according to your disk space and needs.

nginx does not need to listen on port 80 because you will have Varnish there. So any request which is not served by Varnish will be sent back to nginx on port 8080. Nginx will send that back to php-fpm which will process it and send back the results to nginx which in turn will send the results to Varnish which again sends it to browser.

the headers are set in the varnish vcl file. You may see the varnish headers once it's listening on port 80 and delivering the content to browsers.

Try to disable full page cache in Magento go to System->Configuration->Advanced->System and External Full Page Cache Settings. After that flush External page cache in Cache Storage Management.

If still will not work try to disable in Cache Storage Management-> Blocks HTML output

Also Varnish cache needs warm up so try enable Settings->turpentine->Varnish Options->Enable Site Crawler check later in nginx logs if crawler is accessing website

Why install an additional cache when the server you have already has one integrated?

I am not using Magento but similar to Wordpress I am sure it uses many cookies. Varnish will strip all of those unless you tell it to. From my experience you should disable Varnish and enable the Nginx cache to avoid many headaches.

proxy_buffer on;

Make sure to configure the proxy cache size:

proxy_cache_path /var/cache/nginx levels=1:2 keys_zone=microcache:300m inactive=24h max_size=1G;

Also make sure to configure it

proxy_cache_valid 200 30m;

Lower to 15m if you have problems with pageviews/user or stale caching.

 expires 30m;

Those are the values I have tested for some time on a production server. Try them and see if the Nginx cache is performing better than your Varnish cache. In my case it performed way better and is easier to maintain. I will never touch Varnish again. Too hard to maintain.

I am also using Nginx from the past few months and experiencing great improvement in the performance of my various Wordpress blogs and a few PHP websites. I suggest to remove varnish from the stack and enable the Nginx page cache which also called FastCGI Caching. I am sure it will increase performance. this article "How to setup FastCGI Caching" on digitalocean is well described the procedure.
