I have tested
tomcat specific clustering with apache
mod_proxy on ubuntu local VMs for our website high availability and load balancing. The real servers are hosted by
Rackspace cloud server provider and I should implement this on cloud servers once completely done. I tested tomcat clustering with 1 load balancer and 2 web servers. As single load balancer is again a
single point of failure, I'm trying to add one more LB as slave.
In Rackspace there is an option
Load Balancers and here is the link which guides how setting up load balancer which I am not sure to setup because of some doubts as I never did this before anytime.
I heard Rackspace offers to
share an ip between computers, is that so?, then I can use this option.
I am trying
heartbeat configuration on the load balancers and the way I followed from the link seems to work for a site. I have the following doubts here:
- I think I should use
public ipaddress in the place of
virtual/floatingip which is shared and also to which the site domain is pointed, is that so?.
- How could I configure heartbeat for multiple web sites as we have more than one site hosting?.
- I will specify public/shared ip as virtual ip by
eth0:0in the network interface file on both the load balancers. Do you really think it works flawless even if specified the public ip as virtual ip with eth0:0 interface without any interruption?
Finally my goal is to have
ip-failover(master slave) for load balancers and need help on configuring heartbeat for multiple websites(
may be pointing site domains to shared ip does the work?).
If we successed, we can share the success just by telling you 'thank you very much'. Thanks in advance!
