[CentOS] keepalived+LVS
hello, all! if i want to use lvs function of keepalived , i must install ipvsadm ? tks! ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] keepalived+LVS
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 ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] keepalived+LVS
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.

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
?
