Vserver and LVS: possibe?

slurpyx23 · 12-01-2006, 01:24 AM

i've been trying and playing around with Vserver..

Now my next step is to.. do a VSERVER with Load Balancing (ipvsadm)... and run APACHE on the nodes... more

VARIABLES:

* Kernel: vserver-sources

* Kernel to support Load Balancing
i already enabled the following on the kernel:
IP: Virtual Server Configuration --->
<M> IP virtual server support (EXPERIMENTAL)
[ ] IP virtual server debugging
(12) IPVS connection table size (the Nth power of 2)
--- IPVS transport protocol load balancing support[*] TCP load balancing support[*] UDP load balancing support

* Enabled IP forwarding. net.ipv4.ip_forward = 1

* MAIN VSERVER NAME: gentoo
IP (PUBLIC) eth0: xxx.xxx.xxx.xxx
IP (PRIVATE) eth1: 192.168.2.1
- LVS NAT
ipvsadm -A -t xxx.xxx.xxx.xxx:80
ipvsadm -a -t xxx.xxx.xxx.xxx:80 -r 192.168.2.2:80 -m
ipvsadm -a -t xxx.xxx.xxx.xxx:80 -r 192.168.2.3:80 -m

VSERVER NODE1 NAME: node1
IP (PUBLIC) eth0: NONE
IP (PRIVATE) eth1: 192.168.2.2
SERVICE INSTALLED: apache2

VSERVER NODE2 NAME: node2
IP (PUBLIC) eth0: NONE
IP (PRIVATE) eth1: 192.168.2.3
SERVICE INSTALLED: apache2

* I tried laod balancing windows using gentoo as a load balancer and windows running IIS as node. and it works...
(the only thing that i did was.. to point the gateway of the nodes private ip to the ip of the load balancers private ip..)

* i tried reading vserver docs.. on howto specifically point the vservers gateway to the private ip of the load balancer.. but with no luck.

anyone tried this setup.. ? is it even possibe?

basically i am trying to load balance NODE1 and NODE2.

Vserver and LVS? possibe?

Put things on a drawing:

This is what i have done:

1 BIG BOX
+-----------------------------------------------------+

vhost: node1
ip-e0: null
ip-e1: 192.168.2.4 HOST: MASTER
ip-e0: xxx.xxx.xxx.xxx ---------------------- WWW
ip-e1: 192.168.1.1

vhost: node2
ip-e0: null
ip-e1: 192.168.2.3

+-----------------------------------------------------+

* ip forwarding is enabled on the nodes:
echo 1 >/proc/sys/net/ipv4/ip_forward

* i can ping the 192.168.1.* network

* ipvsadm

Code:

IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
  -> RemoteAddress:Port           Forward Weight ActiveConn InActConn
TCP  xxx.xxx.xxx.xxx:http wlc
  -> 192.168.2.3:http             Local   1      0          0
  -> 192.168.2.2:http             Local   1      0          0

* telnet
telnet xxx.xxx.xxx.xxx 80
Trying xxx.xxx.xxx.xxx...
telnet: connect to address xxx.xxx.xxx.xxx: Connection refused

* Is there a way to make this work? via ip tables, routing.. etc.. ?? this thing is starting to confuse me..
