RE: Failover IP router


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/

Or you can use the source rpms for free.

what did people do before the cluster suite was around.

Heartbeat from Linux HA. Same basic thing. Or, as mentioned, a hardware
solution from a vendor. This costs quite a bit though usually.


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 :-)

Subject: Failover IP router


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
