Re: Tomcat and Apache on diffenet machines

[Kumar Vijayaratnam]

David,

Can you state what needs to be implemented on machine1 and machine2, I have posted another query the contents of which I have pasted below:-

I am trying to configure two separate machines one with  Tomcat 3.2.1 and another with apache with mod_jk

The config is as follows:-

Machine1:
----------

Tomcat 3.2.1 + mod_jk

workers.properties

worker.ajp13.port=8009
worker.ajp13.host=localhost
worker.ajp13.type=ajp13

JkMount

server.xml contains the standard configuration

with Context of
                         <Context path="/myapp"
                         docBase="/packages/apps/myapp" />

Machine2
----------

Apache is setup to load mod_jk

This machine also has tomcat loaded

The workers.properties file on Machine2 has the following entry

worker.ajp13.port=8009
worker.ajp13.host=machine1
worker.ajp13.type=ajp13

Then I add the following mount points

JkMount /myapp/servlet/* ajp13
JkMount /myapp/*.jsp ajp13
 

I then startup Tomcat on Machine1 followed by apache on Machine2

When I then type on http://www.myhost.com/myapp/myjsp.jsp

I don't get my application just a message saying 404 not found.
 

I have tried telnet machine1  8009  but nothing is returned...

Regards
Kumar

Yup this is possible ....

and if you are using the loadbalancing module ( so you can have more
than 1
tomcat for your apache(s) to talk to) essential

in workers.properties you should find something like ...

worker.ajp12.port=8007
worker.ajp12.host=localhost
worker.ajp12.type=ajp12
worker.ajp12.lbfactor=1

To define another service try ...

worker.external_1.port=8007
worker.external_1.host=192.168.34.43
worker.external_1.type=ajp12
worker.external_1.lbfactor=1

You can define as many of these as you want.

You can then define a loadbalancer ( if you want to)

worker.loadbalancer.type=lb
worker.loadbalancer.balanced_workers=ajp12, external_1, external_2 etc

then
worker.list=loadbalancer
and you have got load balancing

If you just want to use a single tomcat host then
worker.list=external_1

in your mod_jk.conf

JkMount /test/* loadbalancer

or

JkMount /test/* external_1

Hope this helps

David

PS If you are going to do loadbalancing I suggest you use ajp12
   it takes less time to recover if than ajp13
