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@localhost } notification_email_from keepalived@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 }

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 Looking at the (outdated) log example from the keepalived doc, I seem to miss all the "parsing" of the configuration.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: Feb 20 15:01:18 lvs2 Keepalived_vrrp: VRRP_Instance(VI_1) Entering BACKUP STATE Feb 20 15:01:18 lvs2 Keepalived_vrrp: VRRP sockpool: [ifindex(2), proto(112), fd(9,10)] Feb 20 15:01:18 lvs2 Keepalived_vrrp: Remote SMTP server [127.0.0.1:25] connected.

ipvsadm -l -n shows nothing tcpdump -i eth1 -p vrrp shows nothing
Any idea why keepalived would not bring the VIP up and setup vrrp?
Thx, JD
