Subject: Re: converting mod_jserv to mod_jk
Got it working!!! My correct
tomcat-apache.conf:
LoadModule jk_module libexec/mod_jk.so
JkWorkersFile /app/conf/workers.properties
JkLogFile /app/logs/mod_jk.log
JkLogLevel error
JkMount /servlet1/* servlet1
JkMount /servlet2/* servlet2
JkMount /servlet3/* servlet3
JkMount /servlet4/* servlet4
The asterisk was missing and important.
I think the difference between one worker and many is a matter of function
not style.
In our case we want to have only 1 http server because we want to purchase
only one SSL certificate (and other reasons). Behind that https server we
want to run several independent servlet engines. I think the
workers.properties is 1:1 with the httpd.conf file and thus needs to cover
all the servlet engines behind the server.
Thanks again for the hints and the discussion points.

Your code appears to be missing a lot of the context information that is
automatically generated in mod_jk.conf-auto.
I would recommend that you forget about tomcat-apache.conf, and focus on
modifying mod_jk.conf-auto.
Also, did you make the startup.sh, shutdown.sh and server.xml changes to
support the different Tomcat instances
under mod_jk?
Beyond that, I can't really say anything. I created individual
workers.properties files whre you used one, but that should be more of
a style issue than anything else.

Thanks for the advice based on this and rereading the howto I came up with
the following that still doesn't work. Any ideas?:
tomcat-apache.conf:
LoadModule jk_module libexec/mod_jk.so
JkWorkersFile /app/conf/workers.properties
JkLogFile /app/logs/mod_jk.log
JkLogLevel error
JkMount /servlet1 servlet1
JkMount /servlet2 servlet2
JkMount /servlet3 servlet3
JkMount /servlet4 servlet4
/app/conf/workers.properties
worker.list=servlet1, servlet2, servlet3, servlet4
worker.servlet1.port=8009
worker.servlet1.host=localhost
worker.servlet1.type=ajp12
worker.servlet2.port=8017
worker.servlet2.host=localhost
worker.servlet2.type=ajp12
worker.servlet3.port=8012
worker.servlet3.host=localhost
worker.servlet3.type=ajp12
worker.servlet4.port=8013
worker.servlet4.host=localhost
worker.servlet4.type=ajp12

Subject: RE: converting mod_jserv to mod_jk
I have tried setting up multiple Tomcat instances standalone, but I have not
tried to connect them to Apache,
so I may not be able to help you all the way, but here goes:
First, change the port references in the server.xml and workers.properties
files, and rename these files to something else.
Next, complete the standalone setup changes. (You will want to run
standalone at least once, in order to configure mod_jk.conf-auto.)
In order to run standalone, you need to change startup.sh and shutdown.sh to
point to the new server.xml file version, as follows:
$BASEDIR/tomcat.sh start -security -config ../conf/server_tst.xml "$@"
and:
$BASEDIR/tomcat.sh stop -config ../conf/server_tst.xml "$@"
Now, run Tomcat standalone to create the mod_jk.conf-auto file.
You can then edit the mod_jk.conf-auto file to point to your new
workers.properties file.
If you are using AJP13, you will also have to perform additional manual
edits in this file, as it is built for AJP12, regardless
of what is in the workers.properties file.
Finally, rename mod_jk.conf-auto and include it in httpd.conf.
=========
Now, repeat for your other Tomcat instances.
Let me know if this works for you.
Ed

Subject: converting mod_jserv to mod_jk
I am trying to run multiple tomcat 3.2 servet engines behind 1 single Apache
1.3.14 http server.
Using mod_jserv I had the following tomcat-apache.conf file:
LoadModule jserv_module libexec/mod_jserv_tomcat.so
ApJServManual on
ApJServDefaultProtocol ajpv12
ApJServSecretKey DISABLED
ApJServMountCopy on
ApJServLogLevel notice
ApJServDefaultHost localhost
ApJServDefaultPort 8009
ApJServMount /servlet1 ajpv12://localhost:8009/servlet1
ApJServMount /servlet2 ajpv12://localhost:8017/servlet2
ApJServMount /servlet3 ajpv12://localhost:8012/servlet3
ApJServMount /servlet4 ajpv12://localhost:8013/servlet4
In looking at the mod_jk.conf-auto auto file I do not see any directive that
specifies a port number.
Does anyone have an example that I can try to immitate?
