Varnish: Guru Meditation
I'm installing Varnish following Varnish 3.0.2 documentation
/etc/varnish/default.vcl
backend default {
.host = "127.0.0.1";
.port = "80";
.connect_timeout = 600s;
.first_byte_timeout = 600s;
.between_bytes_timeout = 600s;
}
Lunch command
sudo varnishd -f /etc/varnish/default.vcl -s malloc,200M -T 127.0.0.1:2000 -a 0.0.0.0:8080
Documentation: https://www.varnish-cache.org/docs/3.0/tutorial/backend_servers.html
I just trying to listen on :8080, but i get this error:
Varnishlog

webtelevideo.com:80 works correctly
Answer
Your back-end server is not running. You've configured back-end host "127.0.0.1" but should have used "173.245.60.43" (the ip-address of webtelevideo.com).
