I'm running Amazon Linux.
I originally installed Varnish 3 on this box, but have now installed Varnish 4.
sudo varnishd -a 0.0.0.0:80 -f /etc/varnish/default.vcl
...works just fine to start Varnish 4, and
...works fine to kill it.
service varnish stop
appears to control Varnish 3, and not Varnish 4. I'm very confused!
Why is this? What can I do to help this box forget about Varnish 3?
