Suse 10, Apache2 load balance
Hi all,
I have two standalone webservers. I would like to confgiure for load balance without the use of additional hardware.
Is this possible? After searching i have found that is possible with HAproxy. Is it stable?
Any tutorial how can be done on Suse? Is any rpm available for Suse ?
Thanks

Unfortunatelly RoundRobin will loose the half users when one server goes down.
What other solutions are out there?

No! Applications servers are behind the web server

Microsoft Windows can achieve this by using a proprietary protocol between the two servers. A virtual IP addres is assigned to them and an algorithm decides how to load balance the requests

Anyone implemented using heartbeat?? VFS?
We architected a full-scale webserver and database infrastructure that uses a heartbeat network. We aren't using SUSE, but RHEL 5 with Global File System (GFS), twin NICs (one for network, other in seperate VLAN for heartbeat/fencing needs).
We have found that Xen (as well as other virtual environments) have problems with 'virtual' network cards in different VLANs, thus a limitation in itself -- especially when web serving and heartbeat networks are concerned.
