Hi,
I've been trying to setup a HA cluster with 2 nodes. I've tried a few
howtos, but none have worked for me. One of the best ones:
http://www.ultramonkey.org/2.0.1/topologies/sl-ha-lb-eg.html
Anyway, this is my setup:
- FC 5 in both systems.
- 1 VIP: 10.10.10.2
- 2 RIP: 10.10.10.3 and 10.10.10.4
- 2 Private IP: 192.168.1.1 and 192.168.1.2 for heartbeat and DRBD.
First, I'm trying to have the http service working. Once I get that, I'll
try the mail service too. My configuration files:
- /etc/sysconfig/network-scripts/ifcfg-lo:0
DEVICE=lo:0
BROADCAST=10.10.10.255
IPADDR=10.10.10.2
NETMASK=255.255.255.255
NETWORK=10.10.10.0
ONBOOT=yes
NAME=loopback
- /etc/ha.d/ha.cf:
use_logd yes
keepalive 1
deadtime 10
warntime 5
initdead 120
nice_failback on
udpport 694
ucast eth1 192.168.1.1
ucast eth1 192.168.1.2
node web1
node web2
crm no
- /etc/ha.d/haresources
web1 IPaddr::10.10.10.2/24/eth0 ldirectord::ldirectord.cf
- /etc/ha.d/ldirectord.cf:
checktimeout=10
checkinterval=2
autoreload=no
quiescent=yes
virtual=10.10.10.2:80
real=10.100.20.3:80 gate 8
real=10.100.20.4:80 gate 1
service=http
scheduler=wrr
protocol=tcp
checktype=connect
- /etc/sysctl.conf:
(...)
net.ipv4.conf.default.arp_ignore = 1
net.ipv4.conf.default.arp_announce = 2
net.ipv4.conf.default.rp_filter = 0
Before starting heartbeat I have apache running, ldirectord stoped and
both systems with lo:0 up. When I start heartbeat:
[root@web1 ~]# /etc/init.d/heartbeat start
logd is already running
Starting High-Availability services:

I don't know why it says that eth0 is active, when it's lo:0 which has the
VIP. Anyway, after that I have:
[root@web1 ~]# ifconfig
(...)
eth0:0 Link encap:Ethernet
inet addr:10.10.10.2 Bcast:10.10.10.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
(...)
But
[root@web1 ~]# ipvsadm -L -n
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
... empty :(
What am I doing wrong? Any ideas? Please help,
Pedro.
