Greetings,
Please excuse if there is answer to this in a FAQ somewhere I need to get
the LVS working for this project pretty quick and hope someone can point me
in the right direction I'd greatly appreciate it..
I am attempting to configure an LVS cluster and I have the FOS component
working just great BUT I can't get the LVS router to redirect requests to
http. When I have UDP selected of course I can resolve pull pages from the
HTTP server on 10.2.9.50 but when I enable TCP and the ipvsadm routing table
the redirection isn't working. Running Redhat 6.2 with all the patches and
latest RPM's.
Here's the lvs.cf:
primary = 10.2.9.21
service = lvs
rsh_command = rsh
backup_active = 1
backup = 10.2.9.17
heartbeat = 1
heartbeat_port = 1050
keepalive = 6
deadtime = 18
network = nat
nat_router = 10.11.1.254 eth1:1
virtual server1 {
active = 1
address = 10.2.9.50 eth0:1
port = 80
send = "GET / HTTP/1.0\r\n\r\n"
expect = "HTTP"
load_monitor = ruptime
scheduler = rr
protocol = tcp
timeout = 5
reentry = 10
server innovyx3 {
address = 10.11.1.3
active = 1
weight = 1
}
server innovyx5 {
address = 10.11.1.5
active = 1
weight = 1
}
}
Things I've tried:
You'll notice the netmasks for eth0:1 and eth1:1 are different from eth0 and
eth1 I tried duplicating these with no luck.
Ip forwarding and ip defag is enabled
I can ping the NAT router and the LVS IP
I have the following:

Ipvsadm route:

ipchains route on 10.2.9.21:
target prot opt source destination ports
MASQ all ------ 10.2.0.0/16 anywhere n/a
Ipchains on 10.2.9.17:
target prot opt source destination ports
MASQ all ------ 10.2.0.0/16 anywhere n/a
So from the looks of it everything works great the FOS will failover with no
problems to 10.2.9.17 and switch back just the same but I cannot get it to
route http between my 2 web servers. I am out of things to try at the moment
so any light you can shed on the subject please beam it my way.
