Is it possible to load balance queries to localhost?
Say, I have two servers - I'd like them to be both directors and realservers.
Application connecting to localhost:1111 should be connected to either one or
the other server. Despite many tries, I'm not able to achieve this.
I had partial success with LVS-NAT rules:
-A -t 127.0.0.1:1111 -s lc
-a -t 127.0.0.1:1111 -r 10.0.0.10:1111 -m -w 1 # same server as localhost, works
-a -t 127.0.0.1:1111 -r 10.0.0.20:1111 -m -w 1 # remote server
Where the remote realserver receives the packet:
16:54:18.078365 IP (tos 0x10, ttl 64, id 52411, offset 0, flags [DF], proto TCP
(6), length 60) 127.0.0.1.50427 > 10.0.0.20.1111: S, cksum 0xc03d (correct),
1282046761:1282046761(0) win 32792 <mss 16396,sackOK,timestamp 178066
0,nop,wscale 7>
But I guess it's confused about what to do with it, since it appears to come
from 127.0.0.1.
