apache virtual hosts using different tomcat on different servers
Hi,
Is it possible to have the following scenario configured?
Virtual host
test1.foo.com using apache on server1
configured in workers.properties file as workerA that points to
localhost jboss
And
test2.foo.com also using apache on server1
configured in the workers.properties file as workerB that points to
server2 for jboss
test1.foo.com works. Test2.foo.com goes to the same application because
they are both reading from the localhost mod-jk.conf.
Is there an additional parameter I need in the with in the VirtualHost
tag in httpd-vhosts.conf to get test2.foo.com to go to the remote jboss?
Thank you,
Nic

Try to use apache 2.x with mod_proxy_ajp - there's no mod-jk.conf file,
you configure connections to ajp connectors inside VirtualHost elements
instead.

If mod_jk.conf isn't being loaded, then the module isn't being loaded.
I'm not sure if your Apache httpd installation auto-includes files, but
if the 'LoadModule' directive isn't being read, then mod_jk isn't being
loaded.
Can you change your JkLogLevel to debug and make sure that it's actually
being started? You can also see what the mod_jk log contains after you
request a page you think should go to Tomcat.
Also, please give an example URL that you are trying when you get the 404.

To further explain my testing with virtual hosts test1.foo.com using localhost jboss and test2.foo.com uses server2 jboss.
If I test placing my jkmount statements for either jboss into the virtual hosts tag, I get the server not found error
I also removed the include statement from http.conf that points to my mod_jk.conf
Thanks,
Nicola

Can you post your mod_jk configuration? Please post both mod_jk.conf
/and/ the JkMount directives you are using (and indicate which virtual
hosts they are in).

It's possible, but not likely. Provide a complete path if you are
concerned about it. Also, you could look at your log file to see if
there are any mod_jk startup errors.

My mod_jk.conf setting are below, no error reported in the mod_jk.log file when I have the following in either virtual hosts tag or in mod_jk.conf. I am only testing with test1.foo.com, apache is running on the localhost and my jboss app is on a remote server, worker82

RE: apache virtual hosts using different tomcat on different servers
Posted by Nicola Burns <ni...@firecrestclinical.com>.
Thanks Christopher & Mikolaj for your very helpful information.
I move my 'JkMount *.jsp workerA' information from mod_jk.conf into my virtual hosts tag and restart apache.
When I attempt to access my url test1.foo.com, apache tell me it cannot find my home.do page to login (not found in this server, but when I simply move this back to the mod_jk.conf file again, I can login?
The only thing I leave in the mod_jk.conf file is the location of the log/worker.properties files. Is this a windows relative path issue?
Thanks,
Nicola

The answer is "of course you can"!
It sounds like you want this:
VirtualHost test1.foo.com
workerA -> localhost:jboss
VirtualHost test2.foo.com
workerB -> server2:jboss

mod-jk.conf isn't something standard, so whatever you have has been
home-built. I suspect that you have all your mod_jk configuration in
there, including JkMount statements, and that you are including it at
the top-level.
You have to separate your JkMount statements into your VirtualHosts.
For example, I have a global mod_jk.conf file and it looks like this:
LoadModule jk_module /usr/lib/apache2/modules/mod_jk-1.2.26.so
JkLogFile /var/log/apache2/mod_jk.log
JkWorkersFile /usr/lib/apache2/modules/jk_workers.properties
JkShmFile /var/log/apache2/jk-runtime-status
That's it! Everything else goes into the appropriate VirtualHost along
with the rest of the config for that VH.
Note that the workers configuration is shared. That means that
workers.properties must contain the configuration for all workers across
all virtual hosts. Maybe something like this:
workers.list=workerA,workerB
workerA.host=localhost
workerA.port=[your jboss port]
workerB.host=server2
workerB.port=[your jboss port]
Then, you need something in each VirtualHost that looks like this (your
configuration may vary wildly, but this should get you started):
<VirtualHost test1.foo.com>
... other VH configuration ...
JkMount *.jsp workerA
</VirtualHost>
<VirtualHost test2.foo.com>
... other VH configuration ...
JkMount *.jsp workerB
</VirtualHost>
With regard to Mikolaj's comments, mod_jk just has a different style of
defining endpoints than mod_proxy_ajp. Technically, mod_jk does not
require workers.properties, nor does it require mod-jk.conf.
Hope that helps,
