Nginx with wordpress refused varnish static content requests, gives 503 errors

Posted April 16, 2014 3.7k views
Hi! I just added another wordpress site to my ubuntu server. 2 wordpress sites, not multisite. They use 2 different fpm pool with same config. Their Nginx config files are basically identical except the fpm socket name and listen to different ip ports. Site A works perfectly as usual. Site B ( the newly install one ) gives 503 error for all the static files, e.g.: js, css, png, etc Php and Nginx error logs show no error for this issue. Conformed that varnish and nginx is connected to each others( at least for php ). In fact, Site B could show the wordpress hello world blog post. While stopping varnish and use nginx alone. Site B works perfectly with all static content loaded !! However, static files still give 503 errors after turnning varnish back on. More info: $curl ### return correct files from site A $curl ### return 503 $ sudo netstat -anp | grep varnish [sudo] password for tangrufus: tcp 0 0* LISTEN 1765/varnishd tcp 0 0* LISTEN 1766/varnishd tcp 0 0 ESTABLISHED 1766/varnishd tcp 0 0 ESTABLISHED 1766/varnishd tcp6 0 0 :::80 :::* LISTEN 1766/varnishd unix 2 [ ] DGRAM 11594 1765/varnishd $ sudo netstat -anp | grep nginx tcp 0 0* LISTEN 1960/nginx tcp 0 0* LISTEN 1960/nginx tcp 0 0 ESTABLISHED 1963/nginx: worker unix 3 [ ] STREAM CONNECTED 12812 1960/nginx unix 3 [ ] STREAM CONNECTED 12811 1960/nginx Please help

Confirmed that varnish did make a request to correct nginx backend.
What are the contents of your Varnish configuration: /etc/varnish/default.vcl
