RE: Failover IP router



Barry,

I was told that it is free for RED HAT 5 Advance Platform

You have to pay for it otherwise, around $499, I think

Néstor :-).

Red Hat Cluster Suite is included in RHEL 5 but is an add-on for RHEL 3 and RHEL
4. For completeness, it was included in RHEL 2.1 AS and was not available as an
add-on for RHEL 2.1 ES.

Before RHCS, I used to use keepalived with LVS.

Quoting "Florez, Nestor" <NFlorez@xxxxxxxxx>:

Steven,

I am trying to do the exact same thing and I even open
a ticket with red hat and all the can tell me is that I
need to purchase the cluster suite http://www.redhat.com/cluster_suite/

what did people do before the cluster suite was around.

I trying to duplicate the systems with clonezilla or
systemimager.

SO far for failover I have heard of hearbeat (this is one of the packages
that the cluster suite uses) and DRDB here is an article:
http://www.linuxjournal.com/article/9074
http://linux-ha.org/LearningAboutHeartbeat

If you find out more please let me know because I am in the same search path.

Thanks,

Néstor :-)

I have been googleing for this, but can't seem to find the right answer.
What I am trying to do is to create a failover router on a redhat box.
1. website.com will be on 2 servers
2. website.com has one IP address
3. redhat box router will have the 1 IP address for website.com on it.
4. website.com server1 will be on 192.168.1.10
5. website.com server2 will be on 192.168.1.11
6. If website.com server1 fails, website.com server2 will take over.

We are not worried about cookies that have been set on server1 to be moved
to server2. We are just worried about the second machine taking over. What
would be better is if it could be a load balancing setup so that it will use
both servers, but if one fails, people will not notice it because the other
server will then be taking all of the requests.

I have googled for "Linux failover iptables router" and a few other
combinations of words, but what I keep finding is failover for the outbound
connections. Having 3 Nic cards 1 going to one ISP, 1 going to another ISP
and one going to the internal network. Maybe I am just using the wrong
wording. Any url links for instructions would be appreciated.

Thank You
Steve
