You might also try 'ip addr' to look for the cluster IP.
Certain packages (Like Red Hat Clustering), don't show their IP with
ifconfig, but it will show up with 'ip addr'

Subject: [lvs-users] ldirectord doesn't bind on VIP:port
I'm rather new to the LVS world(although I've been in linux for years), so
pardon my ignorance on some of the topics/technologies. The short story is
that I'm running ubnutu 8.04 LTS x64. I'm trying to set up ldirectord on a
standalone box for now(I'll juice it up with heartbeat in a few weeks).
Below is a quick list of configs and outputs. The problem I'm running into
is that, while ipvsadm shows my VIP and RIP's all up and functioning,
nothing is listening on the VIP:port shown by ipvsadm -L -n. I've followed
http://www.howtoforge.com/set-up-a-loadbalanced-ha-apache-cluster-ubuntu
8.04 as my setup guide, save that I didn't add heartbeat to the mix.
Installed ldirectord with:
apt-get install ldirectord
Here's the config, located in /etc/ha.d:
# Global Directives
checktimeout=3
checkinterval=10
quiescent=no
logfile="/var/log/ldirectord.log"
autoreload=yes
virtual=10.16.14.66:80
real=172.16.1.153:2500 masq
real=172.16.1.153:2501 masq
real=172.16.1.153:2502 masq
scheduler=wlc
service=none
persistent=30
checktype=connect
protocol=tcp
When I launch it in debug mode with "/etc/ha.d/resource.d/ldirectord -d
ldirectord.cf start", here's the initial startup output:
DEBUG2: Running exec(/etc/ha.d/resource.d/ldirectord -d ldirectord.cf

Obviously there's nothing listening on 10.16.14.66, except for SSH which I
can connect to. I've installed apache and had it bind on that address and
port just to make sure there wasn't something funny going on with the IP.
I'm afraid I'm missing something simple, but I've been reading old LVS
mailing lists and other blog posts for days and can't seem to find an
answer. I'll gladly add whatever other config/troubleshooting info is
necessary. Thanks for any help or ideas you can give.
