hello, all! if i want to use lvs function of keepalived , i must install ipvsadm ? tks!
I haven't used keepalived with lvs in ages, but I believe it works directly with the kernel, and therefore does not strictly require ipvsadm. Please note that ipvsadm is a userspace tool for manipulating/querying ipvs entries and is very useful. I've never used lvs on any machine where I didn't also install ipvsadm.
Hope this helps, Barry

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...

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

Assuming I understand you correctly, and assuming you have an init.d script in place, run this command:
grep daemon /etc/init.d/keepalived
Odds are, you're editing /usr/local/etc/keepalived.conf, but the init.d script starts keepalived and tells it to use /etc/keepalived.conf
?

no,my mean is the keepalived lvs need ipvsadm

Do yourself a favour and use HAproxy or something more higher level. I had nothing but bad expirience with lvs for the past few years.
thanks Jure Pečar, *but ,i just know how to complete lvs/tun only use keepalived.* *my experiment need a result . * 2011/3/10 Jure Pečar pegasus@nerv.eu.org
