Subject example mod_jk2 configuration for Apache 2.0.39
Date Mon, 24 Jun 2002 17:39:39 GMT
Just sending this again to see if I can get #@!!***$ Outlook NOT to send
HTML mail!

I haven't set-up anything really complex but the following setup should
work. I haven't got around to trying load-balancing, if anyone does that and
gets it working, please share!

------------------------------- 
in HTTPD.CONF (in Apache2\conf) 
------------------------------- 
  LoadModule jk2_module modules/mod_jk2.dll 

------------------------------------- 
in JK2.PROPERTIES (in Tomcat4.1\conf) 
------------------------------------- 
I just commented out everything. Note that if you are using an AJP connector
with port other than the default of 8009 you should specify here (where it
says channelSocket.port). If you comment everything out JK seems to default
to 8009 (and then 8010, 8011 and so on if you have more than one connector).
If you want need specific ports for multiple connectors then specify
channelSocket.port multiple times e.g

  channelSocket.port=8014 
  channelSocket.port=8018 

if you have two AJP connectors specified in server.xml with port numbers
8014 and 8018. 

---------------------- 
in WORKERS2.PROPERTIES 
---------------------- 

I just copied this file from tomcat4.1\jtc-src\jk\conf into Apache2\conf and
edited it a bit. The really important bits seem to be:

  [channel.socket:localhost:8009] 
  info=Ajp13 forwarding over socket 
  debug=20 
  tomcatId=Tomcat-Standalone 

that actually sets up a worker. I understand that you can specify 

  group=someGroupName 

and create groups of workers for load-balancing. I also believe that every
worker created without specfiying a group is in the default group (I think
it is "lb").

To map contexts use [uri:] blocks like so: 

  [uri:/test] 
  info=Test context mapping 
  debug=20 
  context=/test 

Again, here you can specify which workers serve that context by specifying
group=groupName 

It's a good idea to keep these parts around too: 

  [status:] 
  info=Status worker, displays runtime informations 

  [uri:/jkstatus/*] 
  info=Display status information and checks the config file for changes. 
  group=status: 

you can then hit http://yourapacheserver/jkstatus and get a loads of jk info
that might help you catch config errors 

There are some docs in tomcat4.1\jtc-src\jk\doc\jk2 that might help (but
they're not great). 

Hope this is useful to someone 
cheers
