Hi all,
I finally managed to make everything work :) I have following setup:
-2 lvs nodes, both of them with daemons for connection sync, 2
instances (master and slave)
-ldirectord started as separate process
-heartbeat for high availability, having 2 floating ip addresses,
public and gw for real servers
-3 servers in farm
So far, everything works OK, except one thing. It seems that LVS is
forwarding all incomming connections to same server:
root@ucplb:~# ipvsadm -L
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 192.168.21.150:www wlc persistent 900 mask 255.255.255.0
-> 192.168.20.3:www Masq 3 40 600
-> 192.168.20.2:www Masq 3 0 27
-> 192.168.20.1:www Masq 3 0 0
I am using curl-loader for simple testing. In my case it is set up to
use 22 threads. So it starts 22 different IP addresses and sends
requests from them. I am saying this since persistence is on in my
case. Here is snip of live connections:
root@ucplb:~# ipvsadm -Lc | grep ESTABLISHED

...
So they all do come from various sources, but ends up in same end
server. Why it is so, why my connections are not balanced at all ?
TIA
Best regards,
