[CentOS] keepalived+LVS

[bedo]

thanks for relay!
if i only use ha+lvs configuration of keepalived.the  load balance not work.
then,i install ipvsadm and setup lvs with tun by ipvsadm ,it's work.

command line below:
ipvsadm -A -t 172.16.39.100:80 -s rr
ipvsadm -a -t 172.16.39.100:80 -r 172.16.39.30:80 -i
ipvsadm -a -t 172.16.39.100:80 -r 172.16.39.40:80 -i
