hey,
It seems you are using High Capacity HA & LB configuration
In this configuration
On the LVS servers
Create one new file ifcfg-eth0:0 and add these lines to ifcfg-eth0:0
DEVICE=eth0:0
BOOTPROTO=static
BROADCAST=192.168.1.255 <http://192.168.1.255>
IPADDR=192.168.1.58 <http://192.168.1.58> ----> VIP
NETMASK=255.255.255.0 <http://255.255.255.0>
NETWORK=192.168.1.0 <http://192.168.1.0>
ONBOOT=yes
TYPE=Ethernet
On the both the real servers ifcfg-lo:0 and add these lines in it.
DEVICE=lo:0
IPADDR=192.168.1.58 <http://192.168.1.58> ----> VIP
NETMASK=255.255.255.255 <http://255.255.255.255>
NETWORK=192.168.1.0 <http://192.168.1.0>
BROADCAST=192.168.1.255 <http://192.168.1.255>
ONBOOT=yes
NAME=loopback
TYPE=Ethernet
Please change the eth0 to whatever interface you are using and also change
the ipaddresses as per your setup.
Add the arp_ignore and arp_announce in /etc/sysctl.conf file
net.ipv4.conf.eth0.arp_ignore = 1
net.ipv4.conf.all.arp_ignore = 1
net.ipv4.conf.all.arp_announce = 2
net.ipv4.conf.eth0.arp_announce = 2
On both the real servers the gateway should be the VIP for ex
192.168.1.58<http://192.168.1.58>
.
There are few more important things which I am not explaining like
masquerading ,ldirectord etc.. these things are very clear on the
ultramonkey site.
If anything is not clear do revert back.
