[users@httpd] how to failover apache (running with mod_jk and tomcat)...UPDATE
Sorry I should've mentioned that I'm running this on
Solaris 2.8 (v100's)
All,
I'm a newbie to the apache world and also to this
list. Sorry if this question has been asked already.
I'm running apache 1.3.27 with (mod_jk + tomcat
4.1.18).I was able to get loadbalancing/failover
working with mod_jk + tomcat + apache. But I don't
know how to failover apache itself. Is there a free
pkg which will enable the failover or is the only
option to purchase some expensive proprietary
software.
TIA

not really a problem unless you are totally against having one computer (the
load balancer) running linux.

You need to do some other sort of load-balancing. One possibility is DNS
failover wherein you use multiple IPs for one name.
We use a Cisco Load-Balancer in front of Apache to do the load-balancing for
us. Much better scalability, performance, and, well, load-balancing.
You could also use a proxy Apache in front of the other Apache's which pass
on the requests to the Apache(s) which is running. Of course, you have a
single-point-of-failure there.

Hi,
What I meant was I've got the mod_jk
loadbalancing/failover working between two servers.
But for that to work apache has to be running on both
servers. If apache is not running on server A then
the mod_jk piece will never come into the picture and
all requests to server A will not be forwarded to
server B. What I am interested in doing is to
redirect incoming requests to server A to server B
incase apache is down on server A.

I am not sure what you mean by this? You mentioned
you got it working; are you referring to the config
files?
Please advise.
