Virtualmin

Hi guys,
i wanted to install varnish on vhost sites. I followed this guide: http://virtualmin.com/documentation/system/varnish
For some reason i can only go to my main site. All other sites get redirected to main site. How can i fix this?thanks

Are you sure varnish is listening on port 80?

Check in your headers if you see the ‘Age’ header, otherwise your sites may actually be served by apache which may serve the default as it may not have any vhosts anymore for port 80 (as that was changed to 8080).

The problem is that the etc/default/varnish file opens in notepad.
This is the change Alternative 2, Configuration with VCL

Listen on port 6081, administration on localhost:6082, and forward to

one content server selected by the vcl file, based on the request. Use a 1GB

fixed-size cache file.

DAEMON_OPTS="-a :80 \ <-- i was 6081
-T localhost:6082
-f /etc/varnish/default.vcl
-S /etc/varnish/secret
-s malloc,1024m"

I got some sites working now. I have changed the ports from 80 to 8080 in /etc/apache2/sites-available where the config files are situated. Only main site had port 8080. The others didn’t which was weird. I changed for the other 2 sites too, hope they will work soon.

As for listening to port:i use this command: lsof -i | grep LISTEN | grep http

Here is a sample of the output:
apache2 1317 www-data 4u IPv6 421947410 0t0 TCP *:http-alt (LISTEN)

Is varnish working correctly?I dont see much speed progress…

I used: https://isvarnishworking.uk/ Fail…ish! We detected Varnish on that domain, but the content doesn’t appear to be cached. Best check your configuration.

Make sure you do not serve cookies/sessions and have the expiration date set well by your web application. If this is a Wordpress site, google for a wordpress example vcl (you may be able to strip some cookies except for the admin part).
