NGINX and Varnish Connection failed (localhost:6082)

March 20, 2014 3.9k views
My wordpress site gives error 521 all the times. When I found this error from my server ``` $sudo service varnish reload * Reloading HTTP accelerator varnishd Connection failed (localhost:6082) Error: vcl.load 8d6fb6be-9a0a-4896-be47-e2678e3c2617 /etc/varnish/default.vcl failed ``` Moreover, `varnishlog` shows nothing. I am following this [tutorial]( to set the server up. And, I changed ``` DAEMON_OPTS="-a :80 \ -T localhost:6082 \ -f /etc/varnish/default.vcl \ -u www-data -g www-data \ -S /etc/varnish/secret \ -s malloc,256m" ``` The `/etc/varnish/default.vcl` file is copied from the tutorial. All &a mp; has been corrected to &. It is a fresh droplet. No firewall. Any clue to resolve it? Thanks!!!!

Can you try connecting to it manually to see if we can get some more useful error output:

varnishadm -T localhost:6082

Varnish is an HTTP accelerator and a useful tool for speeding up a server, especially during a times when there is high traffic to a site. It works by redirecting visitors to static pages whenever possible and only drawing on the server itself if there is a need for an active process. This tutorial covers installing wordpress on a LEMP stack (with nginx instead of apache), and then installing varnish.
