Hi,
I've been trying to setup keepalive (vrrp) with LVS in direct routing on Centos 5 and I am stuck...
Installed ipvsadm from the repo (had to touch /etc/sysconfig/ipvsadm because it complained it was missing)
Compiled keepalived-1.1.16.tar.gz
Test setup:
main switch (192.168.16.0/20)
|
eth0: 192.168.28.[226|227]
VIP=192.168.16.123
2 lvs/keepalived servers
eth1: 10.0.0.[1|2]
|
test switch (10.0.0.0/8)
|
10.0.0.[11|12]
VIP=192.168.16.123
test servers (real servers)
192.168.16.[228|229]
|
back to main switch
But let's focus on the 2 lvs servers...
keepalived.conf:
global_defs {
notification_email {
root at localhost
}
notification_email_from keepalived at lvs1.iper
smtp_server 127.0.0.1
smtp_connect_timeout 30
router_id LVS_MASTER ### BACKUP on the backup ###
}
vrrp_instance VI_1 {
state MASTER ### BACKUP on the backup ###
interface eth0
lvs_sync_daemon_interface eth1
virtual_router_id 51
priority 100 ### 99 on the backup ###
advert_int 1
smtp_alert
virtual_ipaddress {
192.168.16.123
}
}
virtual_server 192.168.16.123 80 {
delay_loop 6
lb_algo rr
lb_kind DR
persistence_timeout 50
protocol TCP
real_server 10.0.0.11 80 {
weight 1
}
real_server 10.0.0.12 80 {
weight 1
}
sorry_server 127.0.0.1 80
}

Feb 20 15:01:09 lvs1 Keepalived_vrrp: VRRP sockpool: [ifindex(2), proto(112), fd(9,10)]
And that's it... no VIP showing up... no error message...
Looking at the (outdated) log example from the keepalived doc, I seem to miss all the "parsing" of the configuration.
A bit like if it was stuck in the vrrp child...
On the backup, I get these extra:

Any idea why keepalived would not bring the VIP up and setup vrrp?
Thx,
