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

ipvsadm-1.24-10.x86_64 : Utility to administer the Linux Virtual Server
Repo : base
Matched from:
Filename : /etc/rc.d/init.d/ipvsadm
Filename : /sbin/ipvsadm
I use keepalived/lvs. Yes, you need to install it. Otherwise, there's no way for you to manage the lvs function?
At least, that's what I've been led to believe...
Cheers
Steve
