Hi,
I am thinking of setting up two servers in load balance mode. I would really appreciate your suggestions and hints...
thnx,
Do you want the servers on the same subnet or different subnets? Do you want them geographically separated? What services will the servers run? Httpd, database, etc.?
There is a project called Linux Virtual Server: http://www.linuxvirtualserver.org/ that might be interesting for you to take a look at.
Also, we needed something that would allow us to have an e-commerce site that used servers in two separate geographic data rooms. We wanted both databases to be live allow the system to run even if one datacenter was unavailable. The solutions from Oracle, etc. were too expensive so we wrote our own. We could adapt that to your project if you need.

Hi,
the servers will be on the same subnet. httpd services...You stated that you wrote your own solution. I am curious if it is possible to be implemented using CentOS clustering tools...
thnx,

There might be a way to do it, but I have not explored that yet. You may call me to discuss it. My number is in my signature below.

CentOS has the redhat piranha packages available for install. Piranha is a repackaging of the linux virtual server software, along with a web-based front-end. You can find information about that in the CentOS docs and also by googling for "redhat piranha".

taling abt piranha... i understand that its LVS + webfrontend and is suitable fro webpages and so on. What do we need to make it as a LAMP cluster, i.e with a mysql HA backend as well.
So-> HA of [ LoadBalancer + Apache + MySQL}
Any ideas guys?

We tried Sequioa: http://www.continuent.com/community/lab-projects/sequoia
We wanted automatic failover and geographical distribution of the database nodes. Sequoia only supports master-master operation if the database nodes are on the same subnet.
We did not find anything else out there, so we wrote our own geographically distributed database system. We can adapt that to your project if you are interested.

You will still be limited to a single primary server with DRBD. Here is a line from their site: DRBD's primary-primary mode with a shared disk file system (GFS, OCFS2). These systems are very sensitive to failures of the replication network. Currently we cannot generally recommend this for production use.
