Hi. I'm using LVS in the guise of piranha-0.4.12-1 on RedHat Linux 6.2.
I've successfully gotten LVS working through NAT, hurrah, but I'm planning
on hosting about 75 different web sites in my new LVS farm and I'd rather
not have to maintain three seperate apache configuration files. I'm
inclined to go with direct routing instead of NAT, but I cannot make it
work. To make things easy, I'm working with two nodes.
susan's public interface is 206.66.49.218, her private interface is
192.168.1.1.
johnny's public interface is 206.66.49.219, his private interface is
92.168.1.2.
the virtual ip address i want to put in the cloud is 206.66.49.220,
nat-test.
susan, the router, is configured as follows:
[root@susan piranha-0.4.12]# ipvsadm
IP Virtual Server version 0.9.7 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP nat-test.webslingerZ.com:www wlc persistent 60
-> johnny-internal:www Route 1000 0

Unfortunately, of course, it's not working properly. When I tcpdump the
private interface on johnny, I see the incoming http requests just like
I'd expect, but johnny does not respond to them. he does respond to http
requests directly over his public interface (and his private interface,
for that matter). I'd suspect an apache misconfiguration, but I have not
specified a Listen or Bind directive for apache. ip forwarding is turned
on for both machines. johnny is perfectly able to ping the outside world
from the command line. can anyone suggest anything i might try at this
point? thanks.
oh, has anyone been able to subscribe to the piranha-specific list i saw
advertised here recently? redhat's mail daemon does not respond to my
requests. oddly enough, their web server has also been a bit flaky over
the past few days - should i be worried about using piranha in production?
;)
