Problem with Linux Virtual Server
-
Hello!
I need to do a work of university and I'm interested to use LVS, but I have a problem that I can't solve. I would appreciate it could only help.
I have some virtual machines (virtualbox) of Ubuntu running in my Windows Vista. These machines have connectivity between them. [b]The problem: [/b]for the load balancing and high availability I use ipsadm + keepalived, and it works only if the load-balancer is the same machine that the client. If the machines are different it is'nt work.
I tried many things (for example use ip private in the load-balancer instead a public ip) and I searched information on the web.
The script that I use in the balancer is:
[code]#!/bin/sh
modprobe iptable_nat
echo 1 > /proc/sys/net/ipv4/ip_forward
IPTABLES=/sbin/iptables
REDLOCAL=192.168.1.0/25
$IPTABLES -F
$IPTABLES -t nat -A POSTROUTING -s $REDLOCAL -j MASQUERADE
$IPTABLES -A FORWARD -s $REDLOCAL -j ACCEPT
IPVSADM=/sbin/ipvsadm
$IPVSADM -C
ipvsadm -A -t 10.0.2.15:80 -s rr -p
ipvsadm -a -t 10.0.2.15:80 -r 192.168.1.35:80 -m
ipvsadm -a -t 10.0.2.15:80 -r 192.168.1.36:80 -m
keepalived start [/code]
And in the real servers I only change the default route to point to the balancer's addres:
[code]route add default gw 192.168.1.34[/code]
Thank you very much and sorry for my bad English.
