Hi,

I have an apache server used as load balancer for multiple tomcat servers c=
lusters with mod_jk.

The configuration is to have different workers on different servers and som=
etimes port as well :

#####
# START

# Nodes

JkWorkerProperty worker.server_1_1.host=3Dserver40
JkWorkerProperty worker.server_1_1.port=3D8009
JkWorkerProperty worker.server_1_1.reference=3Dworker.tmplt_worker

JkWorkerProperty worker.server_2_1.host=3Dserver41
JkWorkerProperty worker.server_2_1.port=3D8009
JkWorkerProperty worker.server_2_1.reference=3Dworker.tmplt_worker

# Loadbalancer

JkWorkerProperty worker.lb_cluster1.reference=3Dworker.tmplt_balancer
JkWorkerProperty worker.lb_cluster1.balance_workers=3Dserver_1_1,server_2_1

# END
#####

We use ServerAlias and our DNS registration (in direction of the apache ser=
ver of course) to have an URL by application. For this one, it=B4s cluster1=
..mydomain.com

Everything worked fine till today as we have a new need. We used to install=
only one war on each Tomcat server with the context path "" so the URL was=
http://cluster1.mydomain.com but now we have to host more than 1 war by to=
mcat server. So the Context path will change to the name of the war (no pro=
blem for that) but we don=B4t want to use

cluster1.mydomain.com/war1
cluster1.mydomain.com/war2

but

war1.mydomain.com
war2.mydomain.com

what should I do or add ? Is it on the Apache or mod_jk configuration, or o=
n the Tomcat side ?
Of course I need to add some ServerAlias lines but I don=B4t know what to d=
o with the rest ...

Thanks,

Cyril Vi=E9ville

Hello Cyril,

Take a look at virtual host on tomcat:
http://tomcat.apache.org/tomcat-6.0-doc/virtual-hosting-howt o.html

I think that it is what you where searching for.

Also remember to have the right virtual host on apache to the right
worker.


Cheers,


Martin

Hello Martin,

Thank you for your answer. I can solve the multiple "/" context but my prob=
lem is how to connect an apache virtual host to a tomcat virtual host with =
mod_jk so ?
I can=B4t define the domain on Tomcat because our architecture is a Load Ba=
lancer providing queries to 2 apache servers that load balance after to a j=
boss (so tomcat webserver) cluster so the domain is defined on both of Apac=
he servers. It=B4s my real problem because maybe there is a way finally to =
connect an apache virtual host to a specific war on the tomcat server, no ?

So to make it simple, I want the visitor to go on http://war1.mydomain.com =
(the ip of mydomain.com is on the load balancer that will redirect to the a=
pache cluster that will redirect to the tomcat/jboss cluster thanks to mod_=
jk. The war application can be in a tomcat virtual host or not but I want t=
hat the visitor write http://war1.mydomain.com and not http://war1.mydomain=
..com/war1 ). i know it=B4s a complicated architecture but we want high avai=
lability of our applications.
